Invested In Climate

The vast majority of my interviews have focused on innovations, investing and advocacy related to climate mitigation – that is, what we can do to cut greenhouse gases and minimize the rise in global temperatures. What we do or don’t do now, will have lasting consequences and it is climate mitigation that is driving the transformation of the global economy. So it’s not surprising that mitigation dominates climate investing.  

Adaptation and resilience, meanwhile, focus not on limiting or reversing climate change but rather on improving quality of life in a warmer world. Adaptation ventures receive only a small...

In case you missed it, last week was NY Climate Week. There were well over 1,000 events — from summits with CEO and heads of state, to film screenings, concerts, parties, boat cruises, pitch sessions, hackathons and much more. I tried to sum up my experience at New York climate week in a special episode two years ago. This year, of course, the context was different with a US administration no longer interested in climate, and a lot of green hushing, hand wringing and new language that aims to be less politicizing.

To me, one of the most interesting th...

Climate tech companies face a range of structural challenges to securing the mid stage investment needed to scale their solutions. The lack of capital at this stage prevents many viable, potentially transformative technologies from going mainstream and eliminating gigatons of emissions. That’s why we’ve been running a series of episodes on the Missing Middle in Climate Tech in partnership with Spring Lane Capital.

If you haven’t heard our previous three episodes in this series, check them out at investedinclimate.com, and if you have ideas of other topics that warrant a Deep Dive series please...

I’ll admit it’s not often these days that I’m talking to climate leaders, particularly those working on policy, who say it’s an exciting time. This conversation was like a breath of fresh air. It’s not getting the headlines it deserves, but innovation is literally electrifying our country. Sector by sector, state by state, our economy is being transformed by electric technology replacing outdated fossil fuel applications.

To elevate and accelerate this wave of innovation, Hawaii State Senator Chris Lee and California Energy Commission Chair David Hochschild have teamed up to launch the Electric I...

We’re back with the third installment in our Missing Middle in Climate Tech series, created in partnership with Spring Lane Capital. If you haven’t yet heard the earlier episodes, head to our website for conversations exploring research from CREO and S2G on the financing gap facing climate tech companies caught between early-stage venture and large-scale project finance. And if you have ideas for future series or want to explore a partnership, we’d love to hear from you—reach out via our site (investedinclimate.com/contact).

In this episode, we’re joined by Jason Scott, Par...

As you know, with government funding cuts slowing climate progress across the board, philanthropy is more important than ever. Private foundations offer just a drop in the bucket compared to government funding, but they can still play an important role and catalyze other forms of capital. 

That’s why I’m doing a series of episodes on climate philanthropy. If you have ideas of other foundations that should be part of this series, please reach out through InvestedinClimate.com

We spoke recently with Pisces Foundation President David Beckman on the importance of funding movement infrastructure. 

T...

In this Deep Dive series on Climate Philanthropy, I’m exploring the wide range of ways that foundations are stepping up to support climate progress, especially amid federal rollbacks and inconsistent commitments from large companies. Philanthropic capital is tiny in comparison to government and corporate budgets, but it can still be a helpful tool – especially if wielded strategically. 

Let's set some context: In the United States, there are over 30,000 environmental nonprofits. It's a wildly diverse field with organizations of all sizes and countless focus areas. Since the 1970s, they’ve saved millions of lives through environmental protections that ha...

In the second installment of our Deep Dive: Missing Middle in Climate Tech series, created in partnership with Spring Lane Capital, we dive deeper into why the “missing middle” is not just a gap; it's a structural issue. We're joined by two of the sharpest minds in climate investing: Francis O’Sullivan, Managing Director at S2G Investments, and Rob Day, Co-Founder of Spring Lane Capital. Together, they explore how early-stage innovation and late-stage deployment are well funded, while the crucial middle phase of scaling is dangerously underserved.

We discuss why this gap exists, what solutions are emergi...

The climate transition requires not just allocating trillions of dollars to scale new technologies, build new infrastructure, and transform incumbent industries – it requires getting the right mix of capital to develop, grow, and eventually scale innovations. 

In the world of climate, promising technologies too often don’t find the growth-stage capital that’s needed before large institutional investors can finance reaching scale. Addressing this missing middle is a structural challenge that requires more attention, and today’s episode is the first in a series of discussions on the missing middle in climate, developed in partnership with Spring Lane Capi...

The voluntary carbon markets have been a source of curiosity for me. There’s been a lot of hope that the market would mature and offer a reliable way to offset emissions that otherwise could not be eliminated. Reliability has been the problem, however. Not knowing which carbon reduction projects are additive and truly remove or reduce carbon has held this market back, and I’ve been excited to learn about how new technologies will enable the reliability that’s needed. 

There are many people working on this problem. Dr. Allister Furey, Founder and CEO of Sylvera is one...

Non-dilutive funding isn’t just about landing the grant; it’s about delivering on it with excellence. In the third episode of our Deep Dive Series with Climate Finance Solutions, we go beyond the application and explore what happens after the award. Our guest host Joel Armin-Hoiland, Founder & CEO of Climate Finance Solutions, is joined by two experts who live and breathe this work: Susan Perri, Director of Grants at Climate Finance Solutions, and Jeff Haydock, CEO of ecoCFO.

Together, they unpack the essential strategies behind post-award grant management from navigating audits to implementing smart financial systems, craf...

It’s not yet clear exactly how devasting the loss of federal funding for climate nonprofits and climate tech companies will be, but we know the toll will be high. Beyond the funding freeze, there have also been rumors of other federal action targeting nonprofits in this space. 

No one knows exactly what will happen, but it’s clear that philanthropy is more important than ever. Philanthropy alone can’t fill the gap left by the government, but it can make a real difference.

This episode is the first in a series of conversations we’ll have t...

Non-dilutive funding is a critical part of the capital stack for climate startups. Changes in Washington have made this landscape all the more challenging to navigate. To improve understanding of the opportunities in this space, Invested in Climate is partnering with Climate Finance Solutions on a series of podcast episodes. 

As our first deep dive in this series, Climate Finance Solutions Founder & CEO Joel Armin-Hoiland joined as a guest host and interviewed Tinia Pina, CEO of Re-Nuble and Dimitry Gershenson, CEO of Enduring Planet. They’ve both unlocked millions in non-dilutive capital to accelerate climate progress and sha...

I’ll admit that until recently I knew and thought very little about the potential of Earth observation. It turns out, there’s a huge opportunity here. A report by the World Economic Forum recently estimated there’s almost $4 trillion of potential economic benefit from making better use of the increasingly affordable opportunity to collect and analyze data about our planet. And, the benefit is not just unlocking enormous economic value. Earth observation can help reduce greenhouse gas emissions by more than two gigatons annually through tracking forests, managing wetlands, improving agriculture, and much, much more.

I’m fascinated by the question of how we can improve climate and environmental storytelling. There’s research that shows that 45% of young people in the United States experience climate anxiety so bad that it negatively affects their daily functioning. As we learned during a conversation with Nathaniel Stinnett of the Environmental Voter Project last fall, over 5 million Americans list climate and the environment as their #1 top issue, but don’t actually vote. To me, these are indicators that we need new kinds of storytelling and new ways to experience the climate transition.

To learn about the state...

Alex Wright-Gladstein was one of the first people I interviewed when I launched Invested in Climate nearly 3 years ago. Our conversation has stuck in my mind over the years as her company, Sphere, offers one of the most impactful actions individuals can take to address climate change. 

The action is really simple: Moving our savings out of fossil fuel companies. In the United States, fossil fuels are included by default in retirement savings accounts. If you have a 401(k), IRA, or pension, you are almost certainly supporting the fossil fuel industry. And we’re not talking about chu...

In just its first few weeks in power, the Trump administration has wreaked havoc on the climate tech landscape. An executive order aimed at accelerating fossil fuel extraction and slamming the brakes on renewables and the freeze on all federal grants has already had a devastating effect. Even though the freeze was quickly rescinded, climate companies and organizations across the country are struggling to operate amidst the uncertainty of whether the government will rescind its contractual obligations and cut funding. At stake are hundreds of billions of dollars that have been crucial to developing America’s green economy. 

C...

Many experts today say we’re in the midst of the 6th mass extinction, a relatively short period of time when a high percentage of biodiversity dies out. To be clear, we’re talking about hundreds of thousands of species and an extinction event bigger than anything our planet has seen for over 65 million years when dinosaurs walked the earth. A recent study in the journal, Science, looked at 30 years of research across hundreds of species and showed the close link between climate change and biodiversity loss. It projects that if we can achieve the goals of the Paris Agre...

What 2025 will bring for climate tech is pretty hard to predict. We’ve seen a slowdown in investments at the same time as we see a continued flood of talent into the space, maturing technologies, and a boom in AI that could be transformative for climate solutions. The new administration? Nobody really knows how they’ll orient around climate tech, or how private investors will respond.

There’s a lot of uncertainty, but of course, pros who have been in this game for decades and who study early-stage climate technology closely have some ideas of where we’re heade...

Happy New Year everyone. It's 2025, and we know this year will be tricky in more ways than we can even imagine. I hope our podcast helps you stay inspired and think big throughout the year. 

Having gotten to talk to hundreds of climate tech founders, funders, advocates, and corporate sustainability leaders in recent years, I’ve been inspired by the amazing energy, innovation, and tenacity of climate champions worldwide. I’ve said it before and will say it again, I believe climate is now the biggest movement in human history. Millions of people wake up every day and w...

Let’s talk about nature – the forests, land, oceans, biodiversity, and ecosystem that make this planet liveable and, if you ask me, quite worth saving. Nature regulates our climate – and stewarding nature well could contribute 20-30% of our emissions reduction needs. It’d also support livelihoods around the world and help prevent the mass extinction of many of our planet’s species. 

Nature-based solutions often sound simple – planting and protecting forests, farming in ways that improve soil health, restoring wetlands – but require sophisticated techniques to measure and track their impact. The lack of good nature monitoring systems has contributed...

Today, we’re talking about wildfires and some innovative technology to prevent them. 

Climate change-related heat, drought, and what’s called thirsty atmospheric conditions increase the risks that come with wildfires. These fires have a real impact – they take human lives, create lasting respiratory health problems, destroy billions of dollars of property, and contribute significantly to global carbon emissions. The 2023 fire in Canada that burned an area the size of North Dakota emitted more carbon in five months than Russia or Japan emitted from fossil fuels in all of 2022. It should be noted, of course, that forests reabsor...

When Tom Steyer and Katie Hall came together in 2021 to bring Galvanize Climate Solutions to the world, it promised to be something rather unique. They both bring decades of experience managing many billions of dollars, incredible networks, and insights to find the best, most impactful investment opportunities for climate. Recently, Secretary John Kerry joined Galvanize as a Co-Chair, adding perhaps unparalleled international expertise to their team. 

The firm prioritizes not just financial returns for their investors, but also real climate impact. I was thrilled to sit down with Galvanize Chief Impact Officer Nicole Systrom to learn about h...

There are many reasons to believe the re-election of Donald Trump will be a major setback to climate progress. His previous record, recent campaign, ties to the fossil fuel industry, and perpetuation of misinformation, like the strange idea that wind turbines kill whales, all suggest we’re in for a radical reversal of America’s climate commitment. 

I’ve had many conversations with climate leaders since the election and a different narrative beyond this obvious fear became clear: Climate change doesn’t care who is President. Its impacts will be impossible to ignore. Business leadership and global competiti...

Every once in a while I come across an investment firm with a really different edge and perspective. Overture VC is one such firm. Their specialty is policy – not just understanding the unique opportunities climate tech companies have with government incentives and helping them navigate that tricky terrain, but also actually lobbying for policies that’ll benefit their portfolio companies. 

In the words of Overture Founder and Managing Partner Shomik Dutta, there’s a $1.2 trillion dollar wall of government money coming downhill for climate companies. So Overture’s edge is meaningful and can make a big difference for a wid...

The apparel industry has a massive impact on the environment. The industry is the second-highest consumer of water and it drives almost 10% of global carbon emissions. Despite thousands of smart people working to make this industry cleaner and all sorts of investments by brands, emissions are still increasing. 

To learn about this problem and get an inside look at the efforts to address it, I caught up with two old friends, Jason Kibbey and Evan Wiener. 

Jason was the founder of the Sustainable Apparel Coalition and more recently a technology company called Worldly that helps bu...

If you’re an avid listener, you might know I’m always interested in learning about ways we might improve financial markets for climate ventures. Improving the flow of capital can, of course, be incredibly impactful in helping more climate solutions scale successfully. So I was really excited when I learned about Open Road and the important role they’re playing by offering bridge loans to promising companies. 

Ok, maybe bridge loans don't sound that sexy to you? Think of it this way: if you’re an entrepreneur, what could be worse than running out of money? How about...

After a summer of record heat waves, I’m sure we’re all grateful for air conditioning. And we know, it’s not just about comfort or productivity, but with extreme heat, being able to cool buildings keeps people safe. Yet, it comes at a cost: air conditioning today is responsible for about 3% of global greenhouse gas emissions and demand is set to triple by 2050.

Maybe you’re thinking that heat pumps are the answer and will come to the rescue? They’re certainly an important part of the solution, but until electric heat pumps are plugged into a gri...

We’re weeks away from a historic election. It’s one that will decide the course of climate action in the United States at a pivotal moment, a moment when we can’t afford to slow down or send mixed signals abroad. And, it’s an election that all expect to be decided by just tens of thousands of voters. 

These are all facts that I’m sure you know already. 

Here’s what you probably don’t know: millions of environmentalists don’t vote. These are people who list the environment and climate change as their number on...

If you believe the climate transition is creating trillions of dollars of opportunity, then backing public companies whose business models are centered on that transition and whose growth will be driven by it seems an almost obvious approach. 

That’s exactly what Heather Beatty and ScopeFour Capital are doing, and I was excited to hear what they’re learning and the opportunities they see.

In this conversation, we talk about Heather’s background and how she came to found ScopeFour after decades in institutional investing. 

We talk about their approach, their portfolio, and the oppo...

I’m always excited to talk to climate investors who have been around for a bit, those who were investing during the Cleantech 1.0 phase, saw the ups and the downs, and have stuck through to our current climate tech boom. Some of the challenges that the earlier era of cleantech investing saw – like high capex and long payback periods – are still relevant today, and experienced investors offer nuanced insights into current opportunities and what the future might hold.

I was thrilled to talk to Greg Wasserman. Greg started investing in clean energy almost 20 years ago at Goldman Sachs...

It’s a sad truth that many companies are struggling or failing to meet their sustainability targets. Sensitive to anti-ESG pressure, interest rates, and other macro factors, many are also holding back from making new commitments. Currently, less than 10% of the Fortune Global 500 has a net zero commitment in place. 

Amidst this context, it's all the more important to shine a light on the companies that have made ambitious targets and that are working hard to achieve them. 

IBM is one such company. They began disclosing their CO2 emissions 30 years ago, and since 2010, they’ve cut em...

Hedge funds aren’t exactly known for contributing to climate progress or other ESG goals for that matter. So I was surprised to learn about Corbin Capital, a firm that aims to leverage the activist strategies of hedge funds not just to generate market-exceeding returns for their clients, but to advance environmental and social objectives.

There are trillions of dollars invested in hedge funds that can make a difference in this all-hands-on-deck moment. So why not think about how hedge fund tools can help accelerate decarbonization and other environmental priorities? 

To learn more about this opp...

We know we need to be investing trillions of dollars annually into the climate transition. Venture capital is just a small slice of the pie, but there’s simply no time to slow down its contribution to advancing climate solutions. 

In 2023, however, climate tech venture funding dropped 30% to $32 billion. Whether this was a temporary slowdown caused by high interest rates and the macro environment, or the new normal, will make a big difference.

Recently, I’ve been thrilled to start hearing about funds that are closing new and significantly bigger rounds. 

One such firm i...

After two years of waiting, the SEC finally came out with its new climate disclosure rules. As expected, it was met with a mix of celebration, disappointment, criticism, and lawsuits. The suits came from those who felt the rules went too far and from those who felt they don’t go far enough. 

Disclosure rules are critical to ensuring companies are taking climate change seriously. They ensure investors can consider a company’s climate risks as well as their progress in cutting emissions. 

Beyond the SEC, Europe and California’s rules are also influencing corporate action i...

If you think of Mastercard as simply a piece of plastic that enables you to buy stuff, you’re not seeing their vast network of businesses, their billions of customers, or the potential influence they have on consumer behavior.

There have been countless efforts over the years to encourage consumers to shop more sustainably, but when it comes to the reach and data savvy that Mastercard brings, it’s a whole different ballgame. 

I’ve known Mastercard’s Chief Sustainability Officer Ellen Jackowski for many years, and I was delighted to sit down with her to unders...

Earthshot Ventures isn't just any climate tech venture firm. Having grown out of the Elemental Excelerator, one of the biggest and best-reputed accelerators in the industry, Earthshot is deeply rooted in the early-stage ecosystem. And it turns out there's something else that sets them apart.

Managing Partner Mike Jackson has a knack for coaching founders on what he thinks of as the art and science of fundraising. We're joined today by Mike and Earthshot Partner Ramsay Siegal to hear about their firm, approach, portfolio, and outlook on the market. We dive deep into Mike's insights to helping...

We know that motivating homeowners to invest in energy efficiency retrofits and home upgrades is hard. Energy efficiency might not sound glamorous, but across the US, retrofits can actually cut our residential energy usage in half. 

That’s why when I met Scope Zero CEO Lizzy Kolar, I was excited to learn about her company’s novel way of motivating home upgrades. What Lizzy and her co-founder realized is that our homes are now workplaces.  

And, with employers having to account for emissions for remote workers, they now have an incentive to help homeowners invest in upgr...

We know that addressing climate change will take trillions of dollars of investment. According to the Climate Policy Institute, we’ll need to spend over $10 trillion annually for decades. and we only just exceeded $1 trillion for the first time in 2022. 

I’ll confess, I find these big numbers hard to conceptualize and I’m always glad for more nuanced ways to break them down. That’s why when I saw Oxford’s Climate Tech Initiative’s recent report, I reached out to one of its authors Jamil Wyne. The Oxford report builds on recent climate finance data by asking alm...

At the center of climate progress are scientists. They’re developing new technologies with which we can build a new, more sustainable global economy. Moving inventions from a lab to startup companies to scaled products, however, takes more than science. 

Research scientists had long lacked a support structure to help them build successful businesses. That’s where Activate came in. Founded in 2015 at the Lawrence Berkeley National Laboratory, Activate is a fellowship program that has helped almost 200 science fellows create companies that have now collectively created about 2,000 jobs and have raised about $1.5 billion. 

To learn more a...

If you’re listening to this podcast you’ve probably heard of the Sierra Club. It’s one of the largest environmental organizations in the United States, with about 4 million members and a history of advocacy going back to 1892.

But what do you know about the Sierra Club Foundation? It’s a $200m organization that, as you’d guess, supports the Sierra Club. It also takes on ambitious initiatives to leverage its resources to protect the environment, transform the energy system, and more. One of those initiatives focuses on shifting trillions of dollars out of the fossil fuel econo...

I know it’s wintertime for many of you, but that doesn’t mean we can ignore how cities around the world are heating up and how air conditioning is a growing contributor to climate change. 

Air conditioning is responsible for about 4% of global greenhouse gas emissions. Today, about 20% of electricity used in buildings and about 10% of global electricity use comes from operating air conditioners. With cities heating up and more people able to afford this technology, air conditioning emissions are expected to double by 2030 and triple by 2050.

To understand this problem and some promising solut...

We all know that companies around the world are working to reduce their emissions and, hopefully, achieve net zero. But what does it take to set up a sustainability program? What are the steps in the process? What are the considerations along the way? And who are the partners one might work with? 

Most of this work happens behind closed doors, but sharing insights from corporate sustainability journeys can accelerate progress.  

That’s why Atlassian, a technology company with a real commitment to addressing climate change, decided to open up their own process and share what...

What do you think of when you think about advertising and its role in climate change? I’ll confess the first thing that comes to mind is the fossil fuel industry’s multi-billion dollar campaign to discredit climate science, deliberately confuse the public, and delay climate action. 

But, of course, like every industry, advertising has a role to play in accelerating climate progress. Advertising creatives have storytelling skills that can help distill complex information, shift attitudes, and accelerate the adoption of climate solutions. At a more basic level, the narratives that capture our attention and gain currency in ou...

It feels fitting to start 2024 talking about the big numbers, the big climate financing gaps we face and ways to fill them. 

We know that addressing the climate crisis requires trillions of dollars of investment. It’ll need to come from government, corporations, and big finance, but there’s another stakeholder with an important contribution. Private philanthropic foundations have important roles to play too, particularly in helping communities that might otherwise be left behind and in using philanthropic capital as a catalyst. By de-risking investments and taking concessionary returns, philanthropy can unlock hundreds of billions of dollars of ne...

Happy New Year. It is the beginning of 2024 and I am excited to work along side you to achieve a greater future for our planet.

On this preview episode I give you a glimpse into the upcoming topics of 2024.

There’s a lot we can learn from nature. Processes that happen in nature keep resources in flow, by-products are used and contribute to the health of the ecosystem and there is no waste. Fallen leaves enrich the soil, photosynthesis produces oxygen for animals to breathe, and microorganisms decompose methane and carbon dioxide and produce PHP. 

Oh, not so familiar with that last example? Well, it’s an important one to know about if you care about removing greenhouse gasses from the atmosphere or producing a sustainable replacement for plastics. Today we’re joined by an entrepreneur who for...

As we all feel the impacts of climate change more and more each year, the need to invest in climate resilience becomes more and more clear. The World Bank estimates that by 2050, there’ll be more than 1 billion climate refugees.

It’s not about choosing between solutions to dramatically cut emissions and investments that help communities prepare for and bounce back from climate events – we need them both to limit human suffering as well as geopolitical risks of destabilization caused by climate change. 

Today, we’re joined by two leaders working to advance climate resilience. Nate Matt...

This episode focuses on impact investing and the particular approach of an impact investing firm based in Chicago named Impact Engine. Now that I’ve said the word impact four times, I should probably unpack the jargon. This class of investing aims to create direct, measurable social and environmental impact alongside a financial return. It’s related to, but distinct from ESG investing, which doesn’t necessarily have specific impact goals so much as it aims to avoid harm or risk by considering environmental, social and governance factors. Global impact investing has surpassed $1 trillion annually, and a top focus area i...

When it comes to big companies’ sustainability commitments, I’ve long been impressed by Salesforce. They made sustainability a core company value and pledged to put the full power of their business behind protecting the planet. Hold your skepticism for a minute – this is more than just big promises. They achieved net zero residual emissions and transitioned to 100% renewable energy for their operations back in 2021. They’re part of an effort to plant one trillion trees, and they’ve integrated helping other companies accelerate their own sustainability efforts into their core business through their Net Zero Cloud product. There’s much more...

Today we’re joined by three team members of Braemar Energy Ventures, ESG Head Lori Collins, Partner Don Tappan, a Co-Founder and Managing Partner Bill Lese. I was excited to talk to the Braemar team because their firm has been investing in energy companies for over 20 years and have backed some early category-defining pioneers like ChargePoint and EnerNOC. Since they’re investing in a wide range of companies driving the energy transition, they bring broad insights to today’s climate tech opportunities as well historical lessons from the clean tech 1.0 years. We dive deep into three of their investments, offeri...

The climate transition we’re living through brings so many opportunities to rethink our infrastructure that it could easily be the entire focus of this podcast week after week. Today’s episode focuses on a handful of those opportunities: converting waste into valuable upcycled materials, renewable energy infrastructure, biomass, biofuels and more. 

We’re joined by Ben Hubbard, CEO of Nexus PMG, a company that advises and develops a wide range of infrastructure projects. They’re a fascinating company, and as you’ll hear, they’re engineering sustainable solutions for everything from wood pellets to solar farms to dog food...

Heat pumps have gotten a lot of attention lately. They’re one of the technologies most critical to electrifying buildings and removing our dependency on fossil fuels for heating and cooling.

And, they’re a technology that’s taking off. Sales of heat pumps have grown by double digits for two years running. According to the Sustainability Trends Report published recently by Al Gore’s investment firm Generation, heat pump sales In Europe grew by 50% and they’re now outselling gas furnaces in the United States.  

But did you know there’s more than one kind of heat p...

This week, we’re doing something a bit different outside of our typical interview format. This is a recap of New York Climate Week. I’ll share some of my impressions and you’ll hear from folks like Vice President Al Gore, California Senator Henry Stern, several friends, and fellow climate travelers. You’ll hear some segments from sessions I attended and sometimes it might sound like you’re actually there in a room full of people. If you hear an occasional cough or something, try to just think of it as getting closer to the experience of being there with...

When it comes to plastics, we’re in a real bind. We have yet to develop and scale attractive alternatives to the petroleum-based plastic products we all use every day, and the plastics industry drives well over a billion tons of greenhouse gasses, that’s roughly 4% of total global emissions and plastic-related emissions are on track to double by 2060. Meanwhile, a small fraction – we’re talking less than 10% – of plastics are recycled. 

Creating a circular economy for plastics is vital to eliminating the flow of plastic waste into our environment and to reducing the emissions generated from creating ne...

No matter who I talk to – whether startup founders, investors, or corporate sustainability leaders – when I ask what is needed to really move the needle on climate change, everyone always comes back to the to importance of policy change, of making climate an electoral issue and holding political leaders accountable to take bold action. 

There’s no denying that in recent years one of the most important forces making bold climate action more of a priority, has been the voice of young people. Their cry for change and their committed activism has been impossible to ignore, and the pol...

When it comes to climate tech, there are a lot of new kids on the block, investors that have brought billions of dollars of new capital and have helped fund climate innovation we badly need. 

It’s rare that you find folks who have been investing in climate tech for over a decade, let alone two decades. So I was thrilled to sit down with Neotribe’s Swaroop Kolluri who goes by Kittu, a long-time climate investor who sees enormous opportunity in the intersection of different technologies. We talk about several of his investments – from solar to wave en...

From the growing demand for climate-positive investing, new funds, new approaches for financial advisors, and entirely new platforms for managing one's investments are taking off. This is just the beginning. It's hard to imagine how different investing might be as tens of trillions of dollars transfer to younger sustainability-motivated generations.

Today’s conversation is with two people working to change how people invest today to participate in and support the unique opportunity that is the climate transition. Pete Krull is a Partner & the Director of Sustainable Investments at Earth Equity Advisors, a firm he founded almost 20 years ag...

The podcast is on a few week break for the end of August and will return in early September, 2023!

Fossil carbon is not just burnt for energy. It’s also used as an ingredient for millions of everyday products. But what if, rather than extracting new fossil carbon from the ground, the carbon could be sourced from waste and kept in circulation. 

That’s exactly what a company called LanzaTech is doing. For almost two decades LanzaTech has been using a synthetic biology process to recycle carbon waste and create new products. They went public earlier this year and provide a fascinating example of a climate tech company with a bold vision for transforming how our mater...

We all know that addressing climate change means eliminating greenhouse gas emissions, but have you ever stopped to wonder how we know how much we’re actually emitting? The truth is we haven’t really known, but instead rely on estimates. These estimates fail to provide very specific data about where exactly emissions are coming from, when, and what investment and policy choices might be most effective in turning them off.

Today’s episode focused on an incredibly ambitious initiative called Climate TRACE, a collaboration of over 100 organizations that use a dizzying number of satellites and remote sensor...

The EV revolution is well underway, and we’re clearly in the midst of a massive transition away from gas-powered cars. Consumers are opting for EVs not only to end their costly dependency on fossil fuels, but also because EVs are often just better cars.

For fleet managers, the calculus is different and more challenging. Switching to EVs requires not just an upfront investment, but also operational changes to deal with charging. This is an important problem to solve given the vast number of intensively-used, fleet-owned vehicles on the road. 

We’re joined today by Tenni...

I love talking about food waste. It’s one of the biggest contributors to emissions and something that we all contribute to every day. Reducing how much food goes uneaten is, of course, a big part of the solution, but there’ll always be organic waste. If it sits in a landfill, it’ll emit methane and miss the chance to be used as a resource.

Today’s episode focuses on an Israeli startup that sees organic waste as a precious resource. HomeBiogas turns waste into fuel onsite to be used for heating and cooking. They’re off to the...

Most of our episodes go deep into specific opportunities to address climate change through new technologies, investment opportunities, advocacy, and policy. This episode takes a step back to look at climate and impact investing, how they’ve evolved in recent years, and where they’re heading. Not only have climate and impact investing exploded in recent years, but they’ve also become more mature spaces with more opportunities, tools, nuances, and complexity. 

So I was thrilled to zoom out for this conversation and speak with a true pioneer and leader in this field, Jenn Kenning. Jenn is the Fou...

Decarbonization requires not only eliminating fossil fuels as a main source of energy, but also replacing them as key ingredients in objects we use every day. If you want a crash course on just how much our material world depends on fossil fuels, check out the book How the World Really Works by Vaclav Smil. It’s a fascinating, though sobering read, and one of Bill Gates’ favorite books. 

Today’s episode focuses on pigments, a great example of fossil fuels hiding in plain sight. Take a look around you right now. See any objects that are black i...

If you’re listening to this podcast you clearly care about climate change and it might bother you that your 401k is likely investing in fossil fuels. Many employers have yet to offer sustainable 401k plans, and it sends billions of dollars of capital into fossil fuels every year. Even ESG funds often invest in fossil fuels.

Today’s conversation is about making it easier for everyday investors to invest more sustainably. I’m joined by Zach Stein, Founder of Carbon Collective, a startup offering green 401ks and other sustainable financial products, and by Shaandiin Cedar, an invest...

We often hear about public commitments to reach net zero, but not the nuance, choices, costs, and complexity big companies face when working to decarbonize their global operations. Behind the scenes, any company that is making climate commitments has teams of people focused on decarbonization strategy, carbon accounting, and reporting to figure out how to ween their companies off of fossil fuels and emission-heavy practices in the most effective and cost-effective ways. It’s a laborious task that requires a ton of data and analysis.

This is where SINAI Technologies comes in, a start-up focused on helping co...

Perhaps you’ve heard of the Valley of Death? It’s the phase of development that often kills off startups before they can reach scale. One key challenge is needing to test and refine their technology and gain true validation.  

For a few lucky startups, this is where the Wells Fargo Innovation Incubator comes in to help them develop pilots that provide the insights and credible third-party endorsement needed to grow their technology. The incubator is part of the Department of Energy-backed National Renewable Energy Lab, an institution that’s central to the United State’s investment in renewab...

Today’s episode focuses on sustainable consumption. I know what you’re probably thinking – that the climate crisis requires systemic change and that shifting consumer behavior is slow, it's difficult and it simply won’t add up to enough in terms of the emissions reductions we need. And, I agree – sustainable shopping isn’t enough, but it’s still essential. Demand for climate-positive products helps accelerate new markets. And when consumers see that their choices matter, it influences what they work on, invest in and vote for.

Over the years, there have been many attempts to get consumers to g...

Today, we’re going to talk about mushrooms. More than a delicious pizza topping, fungi can be useful in many different ways and it might even play a heroic role in addressing climate change. How might mushrooms help? Let's count some of the ways. They can be eaten and help reduce our dependence on animal protein. They can replace animal-based leather, sequester carbon, serve as a biofuel, improve soil health, and thereby reduce our need for fertilizers. They can accelerate reforestation, create an alternative to petroleum-based plastics and packaging, and finally, they can help break down and absorb pollutants. 

When it comes to climate policy we hear a whole lot about what’s happening or not at the federal level, and it's easy to miss the critical role of states and cities in responding to climate change. Whether you know it or not, your local government is shaping how your community is preparing for and responding to climate impacts. It’s also making choices driven by the climate transition that affect your daily life. Building codes, electric vehicle infrastructure, public transportation, waste management, green spaces – maybe these things don’t sound sexy, but they’re central to cutting emissions...

Today, we're taking a deep dive into the ocean. Oceans are central to our planet’s climate system. They regulate temperatures, host a vast array of biodiversity, and here's a crucial point - they absorb about a quarter of all CO2 emissions, acting as a massive carbon sink.

But this isn't without consequence. Ocean acidification is a direct result of climate change. It's a silent crisis happening beneath the waves, triggering a mass extinction of coral reefs and the diverse ecosystems that depend on them. 

And, then there’s the crisis of plastics – 10 million tons of plas...

Addressing climate change is not just about eliminating emissions and removing as much carbon from the atmosphere as possible. It's also about people – how their lives, livelihoods, and communities are disrupted by climate impacts as well as by investments in climate solutions. It’s an issue of equity. Pollution and climate-induced extreme weather are disproportionately felt by people of color and low-income communities. And, historically, large-scale investments in new industries have often disproportionately benefited wealthy people with privileged access. 

This is where the environmental and climate justice movement comes in. It's a movement that's grown in numbers, stren...

You probably know that buildings and the built environment account for 40% of our emissions and about 40% of our energy use. Many bright minds are working on this problem, but it remains a tricky one. In the residential market, homeowners are often reluctant to undertake renovations, and when they do, they usually lack the information and contractors they need to consider energy-efficient and climate-positive options.

Now, imagine a world where all homes were rated based on their energy efficiency and environmental impact, and that rating influenced their financial value. Furthermore, imagine if the rating included a recommended retrofitting...

The US Department of Energy (DOE) plays a key role in the rollout of climate funding and policies, so I was thrilled to chat with Chris Castro. Chris is the Chief of Staff of the Office of State and Community Energy Programs at the DOE. Chris brings entrepreneurial instincts and experience, along with clear passion to his role. We talk about Chris’ journey, the implementation of policies you’ve heard of like the IRA, as well as dozens of lesser-known initiatives managed by the DOE that are helping communities across the country decarbonize. There’s lots to learn in this o...

Late in 2022, I noticed a BBC News article stating that HSBC – one of the world’s largest banks – had committed to end funding for all new oil and gas drilling. The commitment alone was noteworthy, but what really caught my eye, as I was looking to understand what drove such a powerful commitment, was the mention of a small nonprofit group based in the UK called ShareAction. I learned that their investigative work, pressure, and collaboration with financial service firms and other companies are accelerating the climate transition. The secret to their sauce is what’s known as shareholder activism...

Today’s episode is a deep dive into climate finance. I’m joined by Marilyn Waite, Managing Director of Climate Finance Fund. Marilyn is one of the world’s leading thinkers, writers and leaders working in several different ways to stimulate the kind and scale of investment needed to address climate change. She brings a deep commitment to climate justice and using finance to ensure the climate transition happens more equitably. As she works to make investments in the US, Europe and China, Marilyn brings a truly global lens. This is a really thoughtful conversation, reflecting on the role of phi...

Imagine if solar panels could be invisible and so thin that you could install them inside windows. Exciting, right? 

This isn’t a science fiction thought experiment, but it’s a real technology being developed by a company called Ubiquitous Energy. And it gets even better: they’re developing this technology in partnership with Andersen Windows, one of the largest and perhaps best-known residential window manufacturers in the US. 

We’re joined today by Ubiquitous Energy’s CEO Susan Stone and Andersen Corporation’s Director of Ventures Prabhakar Karri (who goes by KP), who led Andersen’s inv...

If you’re listening to this podcast you probably agree that climate solutions need to be deployed at scale, across industries, and ultimately influence the lives of everyone. And yet, it’s still hard for most people to invest in and access the solutions our future relies on. 

The episode features two companies that are working towards increasing access to climate tech for investors and consumers.

RaiseGreen is an investment platform that enables non-accredited investors to invest in climate solutions such as climate tech startups, energy efficiency retrofitting programs, green bonds, and renewable energy projects. I’m a...

Agriculture is a sector that needs to be transformed. We need to cut emissions, improve soil health, and sequester more carbon, all while feeding more people. This episode focuses on how California’s Department of Food and Agriculture is investing in this change. 

Why California? Well, agriculture in the Golden State is a big deal. It’s a $51 billion-a-year industry, that grows over a third of the vegetables and three-quarters of the fruits and nuts in the United States. California is a recognized leader when it comes to climate action, and there’s much to learn from its agr...

While new innovations from climate tech startups are exciting, effectively addressing the climate crisis simply isn’t going to happen without big companies making big changes. To be honest, that’s part of why I recently started a new role at NationSwell where I get to help a growing community of chief sustainability officers and ESG leaders take bold action. But don’t worry this episode isn’t about me. 

It’s about Danone, a global dairy company that is taking significant steps to reduce emissions, and the Environmental Defense Fund (EDF), a nonprofit partnering with Danone and other c...

There’s a lot of talk about electric cars, but what about other vehicles like buses and trucks? Buses and trucks create 30% of emissions from the transportation sector, so they need to be a priority. 

This episode focuses on school buses. It turns out that diesel school buses not only pollute the environment, but they cause real health problems for the kids who ride them. Fortunately, the shift to electric school buses has begun, and we’re featuring two people working hard to make it happen. Today, you’ll hear from Duncan McIntyre and Tim Shannon. Duncan is CEO...

The race to address climate change is creating a whole lot of opportunity and a whole lot of work. Just to offer a sense of the scale, the US Inflation Reduction Act is expected to create nine million jobs alone. This is on top of an already booming climate job market. And, climate isn’t just tackled through newly created jobs, but also through new climate responsibilities within existing jobs. 

To learn more about the world of climate work, I sat down with two experts: Peggy Brannigan and Ellen Weinreb. Peggy is the Director of Global Environmental Sus...

When you think of residential solar, you probably think of solar installations that are tied to the grid. These installations have many benefits. You can rely on the grid when you need to, you don’t need to store all the energy you generate in batteries, and you can sell energy back to utilities. But on-grid solar isn’t for everyone, and our future surely requires some mix of on- and off-grid technology.  

To learn about the use case and business opportunity of distributed off-grid solar, I sat down with the founders of two growing, off-grid solar compan...

Given the enormity of climate change and the unprecedented opportunity for innovation that comes with decarbonization, I love learning about ambitious efforts that really take seriously the speed and scale at which we need to invest in change. I’ve long been a fan of New Energy Nexus – an organization that aims to make clean energy accessible to everyone by supporting 100,000 climate entrepreneurs. They take an ecosystem approach, recognizing that entrepreneurs need not just cash, but supportive networks to succeed, and they’ve been building up ecosystems all over the world to support diverse entrepreneurs.

I was thrill...

Get ready. This episode is a really detailed conversation about what could be one of the most important new technologies for addressing climate change. 

Here’s some context: The world has started working to decarbonize virtually every sector of the economy. Yet, even if we had all the political and corporate will, investments and incentives one could imagine, this would still be an incredibly complex process that takes decades. And so, we’ll continue to emit carbon dioxide and other greenhouse gasses for longer than we want.

Essentially, the faucet will stay on, and we need...

Today’s episode focuses on environmental, social, and governance (ESG) investing. What began as a fringe interest in socially responsible investing grew at an astonishing rate and is now completely mainstream, considering the ESG performance of companies. According to a PWC report from last November, ESG investing will grow over the next three years to reach over $30 trillion dollars. That’d be over 20% of all assets under management and a real force influencing how well companies act on climate change, amongst many other issues. 

But ESG can be messy and confusing. To learn more about what it actua...

So far in 2023, we've been looking to the future. Our first episode featured new opportunities with Google, CSAA and IDEO. Then, we did an episode focusing on regenerative agriculture, and another on transforming the global food system.

This week, we'll look to the past and replay one of our first and most popular episodes ever. The episode features Jamie Beck Alexander of Drawdown Labs, a program of Project Drawdown. I thought it's worth replaying as it helps explain the idea that any job can be a climate job, and highlights some really useful tips for creating climate...

Are you ready to uncover the truth about our food systems and its impact on our planet? Last week, we delved into the topic of soil and regenerative agriculture, and this week, we're taking a closer look at the larger picture of food and its role in climate change. As it turns out, food is not only something we interact with every day, but it's also a complex web of industries, processes, and relationships that account for a staggering one-third of greenhouse gas emissions. 

Our special guest, Danielle Nierenberg, is a leading expert and advocate in the f...

Welcome to an episode on agtech, soil health and regenerative agriculture. Here’s some context: one of the big mysteries we’re facing today is how we’re possibly going to feed 10 billion people while transforming agricultural practices that are truly unsustainable. Modern farming is a technological marvel that has dramatically reduced hunger over the last century, but it relies heavily on synthetic fertilizer, which is a significant source of greenhouse gas emissions, and intensive farming practices that have degraded soil’s ability to grow food. 

To understand this issue better and learn about some potential solutions, I sat dow...

Happy New Year - and welcome to the first episode of 2023!

We have two special guests with us today to discuss exciting opportunities for climate progress.

We’re joined by Matt Ridenour, the Head of Startup Ecosystems for Google. Matt is a dear friend who I had the pleasure of working with for several years at IDEO. He’s now leading accelerator programs at Google, and he’s here to talk about an open call for climate founders. 

The second opportunity is focused on helping frontline communities become better equipped to deal with climate...

This is going to be our last episode for 2022. We’ll be back in January with more great conversations. If you have ideas for episodes or topics you’d like us to explore, please reach out through our contact form or on LinkedIn. I’ve had a blast getting this podcast started and I’m excited for it to only get better as we continue. A big thank you to all our guests, to our listeners providing feedback and reviews, and also to Julie Mai, and Aaron & Carey Green for their help behind the scenes.

For our last epi...

The future is electric - especially when it comes to cars. Demand for electric vehicles is far outpacing supply, and automakers are rolling out more or more EV models as governments around the world set clear timelines for when new gas-powered cars will no longer be allowed. 

The transition to EV is good news for our climate. Transportation creates over a quarter of global greenhouse gas emissions, and about 40% of that comes from cars. 

This episode focuses on where we’re at in the EV transition and I’m joined by two true experts. Kyle Stock...

If you look at climate change as a systems problem (which it is), it doesn’t take long to see the important role of finance. Yes, there’s phenomenal growth in ESG investing, alongside funding in clean energy and climate tech. However, overall, our financial system has failed to factor in climate risks and climate impacts. According to the climate disclosure nonprofit CDP, just 1% of companies provide the information that investors need for assessing if they have credible plans for mitigating risks and transitioning to a low-carbon future. Large greenhouse gas emitters have easy access to capital, yet companies are...

If you’re interested in venture investing in climate tech, you probably already know about Climate Tech VC (CTVC). It began as a side hustle and small newsletter and now reaches 40,000 people. In my opinion, there’s really no better source of data and insights around climate tech investing. 

In this episode, I sat down with CTVC's Co-Founder Kim Zou. Kim was an investor at Energy Impact Partners and has been following climate tech investment closely as its taken off over the past several years. In fact, Kim might have actually been the person who coined the term...

You're probably aware that venture capital investing in climate has grown very quickly in recent years, from around five billion in 2016 to over 40 billion dollars deployed in 2021. Large funds drive most of that growth, but small vehicles still play an important role - especially in recruiting new investors to start investing in climate. 

Sundeep Ahuja has helped many investors dip their toes into climate. He's invested in over 100 companies through syndicates that he's led. Full disclosure: I've backed a couple of his syndicated deals. Now, he's focusing on developing funds to deploy more capital into climate startups. S...

Have you come across the idea yet that we need to electrify everything? It's the concept that we need to replace gas appliances with electric ones and power those with renewable energy. It's a simply idea really, and yet it's crucial to eliminating pollution, protecting the environment, saving a whole lot of money and eliminating the illnesses caused by burning fossil fuels. The benefits are massive – but so is the complexity of decarbonizing billions upon billions of buildings.

At the forefront of the movement to electrify everything is Rewiring America, an ambitious organization focused on the systemic ch...

Tackling climate change can’t be left to companies and governments. The nonprofit sector plays a crucial role in everything from research, education, conservation, helping communities cope with climate impacts and much more. There’s literally tens of thousands of environmental nonprofits, and almost all depend on philanthropy to do the vital work they do. 

And yet, only a tiny fraction of global giving goes to climate. That’s part of why Patagonia founder Yvon Chouinard set up an ambitious program called 1% for the Planet. The idea is simple really - companies donate 1% of their revenue to environ...

Ever get carry out food and then feel guilty about all the plastic packaging? Single use plastics are a real problem. Every year over 14 millions tons of plastic end up in our oceans, and plastic that ends up in landfills release toxins that pollute our soil, waterways and food chain. This is not to mention the carbon emissions of producing plastic packaging to begin with. 

The convenience of carry out food isn’t going anywhere, and so we need to find alternatives to plastic packaging. That’s where Dispatch Goods come in. They’re an innovative startup that’s...

I’ve been really curious about seaweed. I hear a lot about seaweed-based businesses, and there’s a lot of hope and hype around the potential for seaweed as a climate solution. The seaweed market has grown to become a $15 billion industry and it's projected to grow to $25 billion by 2028.  

To learn more, I caught up with two aspiring seaweed startup founders: Alexia Akbay and Julia Marsh. Their companies couldn’t be more different – one is using seaweed to eliminate plastic packaging and the other is feeding seaweed to cows so they burp less. This conversation helps highlight...
