Is Wall Street in climate retreat?

Episode Summary

Executive Summary: The episode examines whether banks and investors are truly retreating from climate finance or merely changing language under political pressure. The hosts argue that clean energy investment remains strong, while banks and insurers shift from ESG branding toward climate-risk and resilience frameworks. They also debate private equity write-downs as a valuation correction, not proof clean tech is failing, and defend the IRA as a long-term industrial and supply-chain strategy despite criticism from Jason Furman.

Main Topics: Wall Street’s climate retreat and ‘anticipatory obedience’ (Priority: 5/5): The hosts discuss major U.S. banks leaving climate alliances and whether this reflects a substantive pullback or a rhetorical adjustment driven by political/legal pressure under the Trump era. ESG vs. decarbonization vs. climate risk (Priority: 5/5): The conversation separates broad ESG investing from actual capital allocation to clean energy and from climate-risk management, arguing that many institutions are changing terminology more than strategy. Private equity revaluation of clean energy assets (Priority: 5/5): The hosts analyze write-downs and cost-cutting in clean tech private equity, concluding that the sector was overvalued during the 2021-2022 funding boom rather than fundamentally broken. The role of banks and insurers in climate finance (Priority: 4/5): The episode highlights that banks still lend based on cash flow and risk, while insurers like Chubb are tightening underwriting rules for coal and other carbon-intensive assets. Debate over Bidenomics and the Inflation Reduction Act (Priority: 5/5): The hosts respond to Jason Furman’s critique that Biden overstimulated the economy and that the IRA was inefficient compared with a carbon tax, defending industrial policy and supply-chain reshoring. Permitting, political communication, and implementation (Priority: 4/5): The discussion notes that slow permitting remains a real obstacle and that the Biden administration failed to communicate its achievements effectively, even as policy outcomes continue to build over time. Long-term clean energy scale-up and industrial strategy (Priority: 4/5): The episode closes with a strong argument that batteries, solar, EVs, nuclear, geothermal, and advanced conductors are poised for major scale-up and that the IRA will normalize clean energy as standard business practice.

Key Arguments: Banks exiting formal climate alliances does not necessarily mean they are stopping climate-risk analysis or clean-energy lending; much of the shift is about politically safer language. Climate-risk work and decarbonization capital are different: banks may reduce ESG branding while still underwriting loans, modeling stranded-asset risk, and financing energy infrastructure. ESG did not start as a climate-only concept; it evolved from ethical investing and now is being folded into routine operating and governance practices rather than standalone programs. The clean energy investment ratio cited by BloombergNEF suggests more capital is still needed, but the metric only captures a narrow set of bankable technologies and misses much broader commercialization activity. Private equity losses largely reflect overpaying in 2021-2022 and underestimating time-to-scale, not a failed clean-tech asset class. Many clean-tech businesses behave like infrastructure assets and should be funded on long-duration cash-flow assumptions, not venture-style hype multiples. Banks and insurers are adapting to real physical-climate and affordability risks, including wildfire damage, uninsurable property, and grid-related stress. The IRA should be judged as a supply-chain and industrial competitiveness strategy as much as a climate policy, especially given U.S. dependence on imported clean-tech components. Furman’s critique is seen by the hosts as intellectually selective because it ignores supply-chain fragility, national security, manufacturing buildout, and the political impossibility of a carbon tax. Permitting reform remains a legitimate missing piece, but its absence does not negate the IRA’s longer-term value or the private-sector investment it has already catalyzed.

Data Points: Largest U.S. banks exiting climate alliance: 6 banks - JPMorgan Chase, Bank of America, Citigroup, Wells Fargo, Goldman Sachs, and Morgan Stanley left the Net Zero Banking Alliance in early 2025. NZBA membership remaining: 141 members in 44 countries - Catherine notes the alliance still includes about half of global banking assets. BlackRock alliance departure: 1 asset manager - BlackRock also left its corresponding net-zero alliance. Federal Reserve departure: 1 regulator body - The Fed withdrew from a climate-risk body assessing climate exposure. Low-carbon to fossil-fuel investment ratio target: 4:1 by 2030 - BloombergNEF analysis cited by Jigar says decarbonization spending must reach four times fossil-fuel spending to stay on a net-zero path. Low-carbon to fossil-fuel investment ratio in 2023: 0.89:1 - The ratio at the end of 2023, slightly higher than in 2021 and 2022. Survey share of institutional investors engaged in climate transition: 77% - Schroders survey cited by Catherine found most U.S. institutional investors are already investing or planning to invest in climate transition. U.S. bank climate capital since Paris Agreement: ~$7 trillion - The episode notes around $7 trillion invested among the world’s top banks since 2015. BlackRock renewable fund performance: Negative returns and write-down - Used as an example of private equity reevaluation in clean energy. Battery manufacturing scale in the U.S.: 50 GW - Jigar says the IRA has already helped bring 50 gigawatts of module manufacturing to the U.S. Projected EV battery manufacturing timing: By 2027 - He predicts most EV batteries used in the U.S. will be manufactured domestically by then. Projected utility-scale battery manufacturing timing: By 2029 - He says most utility-scale batteries will be made in the U.S. by then. Factory construction growth: More than doubled in 5 years - Catherine cites this as evidence of IRA-driven industrial momentum. Global solar deployment last year: ~600 GW - Jigar says solar additions were about 600 gigawatts last year. Global solar deployment next year forecast: 700–800 GW - He projects another large increase in solar installations. Share of clean energy added to the grid: 90% - Jigar says roughly 90% of new grid additions are clean energy technologies.

Pivotal Quotes: "There was an exuberant couple of years where tourists entered the space and they're now leaving." — Scott Jacobs (quoted by Catherine): Used to describe the private equity cleanup in clean energy investing. "If we want fossil fuels to not have as much market share, then we need to flood the zone with clean energy." — Jigar Shah: Argument that capital exclusion is less effective than scaling alternatives. "What's wrong is changing the actions you do. And I think the actions are changing far less than the words are changing." — Catherine Hamilton: On banks shifting from ESG language to resilience and climate-risk framing.

Implications: Climate finance is not disappearing; it is being reframed. Expect less ESG branding, more risk management, and more disciplined capital deployment. Clean energy’s long-term growth story remains intact, but valuations, permitting, and policy communication will shape how quickly it scales.
