Episode Summary
Executive Summary: Jason Jacobs interviews Nat Cohan of EDF about his path into climate advocacy, EDF’s pragmatic market-based approach, and why solving climate change requires both urgency and patience. Cohan argues for durable, bipartisan, economy-wide policy, especially enforceable limits on pollution, while also supporting innovation, deployment, and public mobilization across the U.S., China, and other major emitters.
Main Topics: Nat Cohan’s climate origin story and career path (Priority: 5/5): Cohan traces his environmental concern to his grandmother, the Mountain School, and early EDF work in the 1990s, then describes moving between academia, EDF, and the Obama White House before returning to EDF leadership. EDF’s pragmatic, market-oriented advocacy model (Priority: 5/5): He explains EDF’s role as a solutions-oriented advocacy group that combines research expertise with practical political strategy, emphasizing getting policy done in the real world rather than just identifying the theoretical best answer. Urgency vs. hope in climate communication (Priority: 5/5): Cohan wrestles with how to balance the reality of severe climate risk with maintaining hope and momentum, warning against people moving directly from complacency to despair. Policy design: enforceable limits plus flexibility (Priority: 5/5): He argues that solving climate requires hard caps or declining limits on emissions, paired with flexible mechanisms like cap-and-trade, taxes, or hybrids to achieve reductions efficiently. Global strategy and the importance of China and the U.S. (Priority: 4/5): Cohan stresses that any serious climate strategy must center the biggest emitters, especially China and the U.S., and describes the drivers behind China’s climate policy: air quality, industrial opportunity, and international status. Bipartisanship and policy durability (Priority: 4/5): He makes the case that major climate policy must be durable enough to survive political swings, which in his view requires bipartisan support rather than narrow partisan victories. Where $100 billion should go (Priority: 4/5): Cohan proposes allocating large resources across political mobilization, breakthrough innovation, tropical forests, and clean-energy deployment, while insisting that policy is what shapes markets.
Key Arguments: Climate is a long game: immediate action is urgent, but the needed transitions in policy, markets, and behavior will take decades. Advocacy should start from the decision-maker’s problem; advocates are effective when they help policymakers solve constituent and political problems while advancing climate goals. EDF’s comparative advantage is combining rigorous analysis with advocacy and practical implementation. Market mechanisms matter, but only if they are embedded in enforceable policy limits that reduce pollution over time. The climate fight requires both deployment of current technologies and continued investment in breakthrough innovation. Bipartisan support is needed because durable climate policy must outlast election cycles and avoid becoming perpetually contested. China is central to global climate progress, and its incentives include local air quality, economic opportunity in clean-tech industries, and international leadership. Personal climate actions can matter indirectly by increasing awareness, political engagement, and social pressure, but they can also backfire if they create a false sense of completion. The most powerful lever may be mobilizing political will in major emitters so that policy changes shift market incentives at scale. When policy windows open, advocates should aim high; settling for half-measures can squander rare opportunities.
Data Points: EDF membership: more than 2 million members - Described in the show intro as part of EDF’s scale and reach. EDF staff: 700 scientists, economists, policy experts, and other professionals - Shown in the intro to emphasize EDF’s analytical capacity. Year Nat Cohan joined EDF initially: 1994 - He landed a junior research assistant role at EDF in Washington after college. Year Cohan returned to EDF after academia: 2007 - He came back from Yale to work on federal climate legislation. White House tenure: 2011 and 2012 - He served as special assistant to President Obama for energy and environment. Obama-era policy team size: about 3-4 people - Cohan describes a small White House core group handling most energy and environment issues. China’s subnational ETS pilots: 7 cities and provinces - He notes these are precursors to a national emissions trading system. China national ETS launch: next year - In the transcript’s timeframe, he says China’s national power-sector carbon market was set to launch the following year. Colorado climate target: 80% below 2005 levels by 2050 - He cites Colorado as an example of an ambitious state climate law. U.S. climate action window: 2011-2012 as a low point - He describes this period as a nadir for U.S. federal climate policy under political opposition. Warming thresholds referenced: 1°C currently; 1.5°C within decades; 2°C before century’s end if unchecked - Cohan uses these to explain the urgency derived from IPCC findings. Potential allocation amount: $100 billion - He is asked how he would allocate a large pot of money to maximize climate impact.
Pivotal Quotes: "the balance between urgency and hopefulness" — Nat Cohan: He describes the central communication challenge in climate advocacy. "Climate is a long game" — Nat Cohan: He argues that meaningful climate solutions require patience and durable policy over decades. "We need it all, right? We need them all." — Nat Cohan: He explains that the climate solution portfolio must include deployment, innovation, standards, pricing, and other tools.
Implications: Listeners should take away that climate action is not a single-tech or single-policy problem. Real progress requires durable political coalitions, broad public engagement, and a portfolio of policies and innovations deployed over decades.
