    The carbon removal industry often focuses on two big questions: which tech works, and who pays for it? But it’s not just about tech or financing. We need clarity on methodology, net-negativity, land use, permits, and funding before selling carbon credits at scale. As the ecosystem grows, organizations like Isometric, CarbonPlan, Enduring Planet and AirMiners are paving the way forward. Read Jamie Wong’s op-ed, "For Sale: A Promise to Remove Invisible Gas," in this earlier edition of the MCJ newsletter for the full story.

These larger turbines could transform the economics of onshore wind, making energy cheaper and more accessible. In this episode, Radia, Inc. CEO Mark Lundstrom and Cody dive into his company's verticalized approach to addressing a major challenge in wind energy: the physical limitations of transporting turbine blades via the U.S. interstate highway system. 🎙️ Listen at the links below!

    “There’s a predilection in this world to believe that the foundational status quo will stay the same... particularly in business, that’s not true.” – Tom Steyer, Galvanize Climate Solutions Cody Simms and Tom discussed how the energy landscape is fundamentally shifting.

Where do you think this transformation will lead and what’s your prediction for the “new” status quo in energy and industry? 🤔 🎧 Listen to the full conversation: https://mcj.news/steyer

    We're days away from what's considered the most important election for climate and clean energy. It's only fitting that this week's MCJ newsletter features a piece from Michelle Deatrick, Founder and Chair of DNC Environment and Climate Crisis Council. With Vice President Harris’s tie-breaking vote in the Inflation Reduction Act, our clean energy economy has flourished, creating hundreds of thousands of new jobs and supporting the growth of innovators—including some of MCJ’s own portfolio companies like Moment Energy, Arcadia and Sublime Systems. But all this progress is at risk. Read the article to find out how you can make an impact with the time we have left.

    Since 2019, we’ve had 500+ conversations with the leaders and innovators driving the energy transition. Through these discussions, our perspective has evolved. ⛈️ Between intensifying extreme weather, from wildfires to hurricanes, and the ripple effects across global markets, climate change is inevitable—it’s already here. It’s reshaping our lives, economies, insurance, and response systems. ⚡️At the same time, the energy transition—the rewriting of industries to be cleaner, more profitable, and more resilient—is also inevitable. We’ve realized our show is less about any individual journey and more about understanding these inevitable forces shaping our future. It’s about navigating climate impacts, industry adaptation, and driving innovation. And with that in mind, our new name was right in front of us.
