Tackling the plastics crisis via blended finance with Circulate Capital & the Circulate Initiative, Ep #69
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 new plastic products. Today’s conversation focuses on an ambitious effort to catalyze and fund the systems change needed to get us there. Circulate Capital is working to unlock a billion dollars to invest in circular solutions, and its partner Circulate Initiative offers research and insights to track this space and help recruit more private and public investment in this space. We’re joined by Ellen Martin, Circulate Capital’s Chief Impact Officer, and Umesh Madhavan, Research Director for Circulate Initiative. We talk about the history and state of the plastics crisis, their current efforts, and the investment opportunities they see. Circulate has impressive momentum in building coalitions of different kinds of investors – from governments to Fortune 100 companies. This blended finance approach is surely a key to mobilizing the commitment we need, and I was grateful to learn so much about it through this conversation. Here we go. In today’s episode, we cover:[3:18] Circulate Capital, Ellen’s role & where they’re based geographically[4:24] Circulate Initiatives & Umesh’s role[5:24] How Circulate Capital & Circulate Initiatives are connected[6:56] The plastics problem & what’s causing it[8:57] The plastics problem timeline[11:01] Overlaps between plastic pollution, climate, ocean health & circular solutions[13:04] Why Circulate Capital was established & what they’re aiming to do [16:41] De-risking the investments using concessionary capital [19:08] Using a highly collaborative investment ecosystem to solve the plastic waste challenge[19:47] Circulate Capital’s role & how it’s focused[20:59] Working with LPs to scale circular solutions[23:24] What should we all know about the plastics economy & how it works[25:06] Asia & Latin America plastic markets[27:50] Breaking down $4B in investments in the circular economy for plastics[31:27] The greatest opportunities from an investment lens[34:15] What more needs to be done around the plastic waste problem[36:32] The Plastics Treaty, its state of play & what impact will it have[39:15] How plastic economies differ between Asia & Latin America[41:25] Investment opportunities in the US & Europe[43:25] Visions for the future of plasticResources MentionedCirculate CapitalCirculate InitiativeOECD: Plastic PollutionPew Charitable Trusts: Preventing Ocean PlasticsCirculate Capital Ocean FundPrevented Ocean Plastic Southeast AsiaDelterra & Circulate Initiative: Honing the Habit: Four Insights on Spreading Recycling Behavior ReportCirculate Initiative: Plastics Circularity Investment TrackerInternational Legally Binding Instrument on Plastic PollutionCircAcelon Chemicals and Fiber CorporationAceGreenConnect with Ellen Martin & Umesh MadhavanConnect with EllenConnected with UmeshConnect with Jason RissmanOn LinkedInOn TwitterKeep up with Invested In ClimateSign up for our NewsletterLinkedInInstagramTwitterHave feedback or ideas for future episodes, events, or partnerships?Get in touch!

Sunrise Movement & young people's fight for bold climate action, Ep #68
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 policies they’ve fought for have gained real headway. In the United States, at the center of youth climate organizing is an organization named the Sunrise Movement. They’ve been around for less than a decade but have mobilized effectively and are credited for inspiring and advancing historic climate policies like the Inflation Reduction Act. Today we’re joined by two leaders of the Sunrise Movement, Matthew Miles Goodrich and Aru Shiney-Ajay. Miles was one of the founders of the movement and leads fundraising. Aru has been involved since she was 19 and now leads Sunrise’s strategy. They’re both inspiring representatives of the bold vision and commitment that’s made Sunrise so successful and that we all need to bring to climate work.In today’s episode, we cover:[3:35] Miles’ background, role with Sunrise & how he got involved[5:34] Aru’s background, role with Sunrise & how she got involved[8:31] The origin & history of the Sunrise Movement[11:45] The reach that Sunrise has achieved & how it's been successful at getting young people involved in climate action[13:54] Why has Sunrise gathered so much momentum[17:00] How many people have been involved in Sunrise & how are they able to manage their volunteer army[19:31] Sunrise’s wins & progress[21:55] Sunrise’s role surrounding the Inflation Reduction Act and the impact of the IRA & other recent climate policies[27:57] Sunrise’s current strategy & priorities[32:34] Why is declaring a climate emergency needed & what would it lead to[34:45] Sunrise’s theory of change[37:44] The lawsuit against the state of Montana & implications of the case[39:45] Pivotal moments for climate & the progress being sought[41:20] Hopes for Climate Week[42:01] What else needs to happen to adequately address climate changeResources MentionedSunrise MovementSunrise Movement: Green New DealSunrise Movement: Declare a Climate EmergencyConnect with Matthew Miles Goodrich & Aru Shiney-AjayConnect with MilesConnected with AruConnect with Jason RissmanOn LinkedInOn TwitterKeep up with Invested In ClimateSign up for our NewsletterLinkedInInstagramTwitterHave feedback or ideas for future episodes, events, or partnerships?Get in touch!

Creating a circular economy of carbon with LanzaTech, Ep #65
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 material world is built. Perhaps that’s why they were recently recognized by the prestigious Earthshot Prize. In this episode, I’m joined by LanzaTech’s Chief Sustainability Officer Freya Burton and Chief Science Officer Zara Summers. We talk about the growth and evolution of LanzaTech, their effort to create a circular economy of carbon, their technology, partners, and much more. This episode will push your thinking in some interesting ways.

Climate TRACE's bold plan to map emissions with satellites, sensors & AI, Ep #64
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 sensors to actually detect and track emissions at a global level. Vice President Al Gore is a Co-Founder of the initiative, along with Gavin McCormick who runs a nonprofit called WattTime. We’re joined today by Gavin who explains how Climate TRACE works, the Vice President’s role in the effort, their theories of change, surprises, progress, and hopes for the initiative, and much more. Climate TRACE is positioned to play a central role in improving transparency and planning at a global level, and I was thrilled to get to learn more about it through this interview.

Electrifying fleets with Spring Free EV & Spring Lane Capital, Ep #63
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 Theuer, Co-Founder and Chief Product Officer of Spring Free EV, a startup that provides EVs as a service to fleet managers across the US, as well as one of her investors, Rob Day, Partner and Co-Founder at Spring Lane Capital. Don’t be confused by the names of Spring Free EV and Spring Lane – they’re two separate companies, but they are united by their shared excitement for the enormous opportunity to electrify vehicle fleets. We talk about the size of that opportunity, Spring Free’s product and traction, how EVs can transform fleets from depreciating assets into revenue opportunities, and much more. So buckle up – sorry had to go there – and enjoy. In today’s episode, we cover:[3:36] The market & need that Spring Free EV is filling[5:50] The size of the fleet market & why is it Spring Free EV’s focus[7:47] How many companies have fleets & how many cars are owned by fleets[8:06] How Rob sees the market as an investor[11:19] The holdback on CNI fleets[12:11] Cutting the cost of EV ownership in half for commercial fleet owners[15:38] EVs & the title as the better car[18:38] How Spring Free EV stands out[21:56] The most important milestones that Spring Free EV should be pursuing[23:31] Cars, customers & capital[25:44] What will it take to get to the gigaton goal[26:21] How Spring Free EV’s work will change[29:28] How & when Rob got involved in climate investing & how he sees the market evolving[32:50] Spring Free’s unique approach & why it's needed for climate companies today.[35:52] What else is Rob excited about right now[38:04] What else needs to happen to accelerate EV adoptionResources MentionedSpring Free EV Spring Lane CapitalConnect with Tenni Theuer & Rob DayConnect with Tenni on LinkedInConnect with Rob on LinkedInConnect with Jason RissmanOn LinkedInOn TwitterKeep up with Invested In ClimateSign up for our NewsletterLinkedInInstagramTwitterHave feedback or ideas for future episodes, events, or partnerships?Get in touch!

Turning waste into energy onsite with Closed Loop Partners & HomeBiogas, Ep #62
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 races selling their products for a range of applications – from backyards to hotels – and they’re just getting started. We’re joined today by HomeBiogas’ founder Oshik Efrati, and one of their key investors Ron Gonen from Closed Loop Partners. We talk about both guests' backgrounds, the challenges and opportunities to create a circular economy, anaerobic digestion, how HomeBiogas turns waste into energy, the opportunity they see, and much more. Here we go. In today’s episode, we cover:[3:03] Oshik’s background & what led him to launch HomeBiogas[4:51] Ron’s experience in recycling and waste & what led him to founding Closed Loop Partners[7:08] Closed Loop Partner & the ways it’s working to eliminate waste[9:06] The impact of waste on climate & why solutions are needed[10:32] How Oshik sees the problem & what his company is working to solve[11:43] How HomeBiogas is approaching the problem[13:44] Anaerobic digestion & what else makes HomeBiogas’ systems possible[16:09] The potential that Closed Loop Partners sees in HomeBiogas as an investor[17:43] Oshik’s view of the market opportunity[18:19] Measuring climate & environmental impacts[19:51] HomeBiogas’ traction, different applications & go-to-market[21:06] The process of converting waste to energy in buildings[22:25] The toilet market & what HomeBiogas is able to do with human waste[24:33] What’s most critical to HomeBiogas’ success[25:39] Partnerships that HomeBiogas has developed & is looking for now[28:06] The residential market in the US[31:19] The next few years from a business & impact perspective[33:03] How does this space compare to other circular economy verticals[34:22] What else is needed for realizing the circular economyResources MentionedHomeBiogas Closed Loop PartnersConnect with Oshik Efrati & Ron GonenConnect with Oshik on LinkedInConnect with Ron on LinkedInConnect with Jason RissmanOn LinkedInOn TwitterKeep up with Invested In ClimateSign up for our NewsletterLinkedInInstagramTwitterHave feedback or ideas for future episodes, events, or partnerships?Get in touch!
