Podcast: LSE: Public lectures and events
Host: London School of Economics and Political Science
Episode Date: September 22, 2025

Overview

This episode, recorded during LSE's Environment Week 2025, brings leading global voices together to examine the high-stakes agenda ahead of COP30 in Brazil. With climate progress imperiled by geopolitical tension, skepticism on net zero, and mounting adaptation needs, panelists explore the intersection of climate finance, mitigation strategies, and realpolitik. The conversation centers on bridging trust and delivering action—moving from rhetoric to results for a climate-safe, equitable global future.

Key Discussion Points & Insights

1. The State of Climate Action and the COP Process

• Opening sentiment: Robin Burgess, organizer of LSE Environment Week, notes both the vibrancy of student-led engagement and the elevated LSE focus under its new Global School of Sustainability. The centrality of COP30 this year marks a crucial inflection point.
  "Now people realize that climate change and environmental degradation is sort of the number one challenge out there." [01:20, Robin Burgess]

• Susanna Morato (LSE Vice President):

  • Warns of climate action backsliding: net zero commitments diluted, environmental concerns losing priority, and biodiversity threatened.
  • Offers hope: the High Seas Treaty, growth in marine protected areas, slowing Amazon deforestation, and renewables reaching 30% of global electricity.
  • Frames LSE’s mission: leveraging social science for climate solutions, with COP30 research feeding into global negotiations.
    "Progress is possible when evidence, ambition, and collaboration come together." [02:46, Susanna Morato]

2. The Challenge: “COP30 Has to Be Different”

Sherry Rahman (Former Pakistan Climate Change Minister)

• Draws on frontline experience—Pakistan’s rolling 53℃ summers—to set the existential stakes and urgent expectations of the Global South.

• COP’s credibility crisis:

  • Multilateral process still matters, but lacks enforcement—pledges aren't binding or auditable.
  • Trust deficit: financing falls far short, adaptation remains a “stepchild” to mitigation.
  • Climate finance currently double-counted and slow—“projectized” and mismatched to changing realities.

• Clear demands for COP30:

  • Deliver meaningful, not performative commitments.
  • Define climate finance transparently and auditable (not “ODA relabeled”).
  • Balance adaptation and mitigation—most climate finance goes northward.
  • Stocktake process must update carbon, finance, and even military emissions.
  • “Don’t load developing countries with more debt as part of climate financing. The Bretton Woods system is not working, not for developing countries anymore.” [20:40]
  • End the cycle of “band-aid on bullets”: slogans like “leave no one behind” ring hollow.

Memorable quote:
"So from that context, I’m just going to say it very plainly. COP30 has to deliver much more than any other COP to rebuild trust and confidence in the Global South. It has to be less performative and more meaningful." [09:42, Sherry Rahman]

3. Economic Solutions: From Hot Air to Hard Numbers

Prof. Jose Schenkman (Columbia/Princeton; Chair, COP30 Finance Committee)

• Current trajectories: NDCs, even if fulfilled, “are a recipe for disaster”—the world heads toward 2.6–2.8℃ warming.

• Proposals from the COP30 advisory group:

  • Anchor new NDCs to a 2050 net zero trajectory.
  • Mobilize $1.3 trillion/year in public and private flows to developing countries by 2035—a huge gap from today’s $190 billion, mostly domestic and loans.
  • Emphasize low-cost emissions reductions first (global carbon price or ‘coalition of the willing’ if a true global market is infeasible); include negative emissions and nature-based solutions.
  • Propose a self-governing central authority for carbon/nature credits, with rigorous measurement and verification.

• Role of innovation & financial realism:

  • "There's no empirical evidence that investors are willing to pay relevant premium for green bonds."
  • Financial engineering isn’t a miracle; risky projects still need public support.

• Climate justice mechanisms:

  • Debt-for-adaptation swaps—rich countries accept haircuts in exchange for adaptation spending, lessening debt burdens and climate risk, and reducing crisis-driven migration.
  • Grand bargain: rich countries pay for the harms caused by their emissions; emerging economies commit to emission cuts.

Memorable quote:
"Both the unconditional and conditional NDCs lead to a 50% chance of reaching 2.6 or 2.8 degrees. That's really disastrous—a risk we don't want to take." [23:10, Jose Schenkman]

4. The Grand Bargain: Trading Money for Tons

Prof. Michael Greenstone (University of Chicago)

• The “cruel arithmetic” of climate math:

  • Even if OECD countries reach zero emissions, non-OECD would need to cut by 88% to hit 2℃.

• Most damages accrue in the Global South: 98% of mortality impacts from every ton of CO2 land outside the OECD.

• Proposes the “Global Climate Grand Bargain”:

  • Voluntary, incentive-aligned: OECD compensates Global South (annually, based on actual damages caused), in exchange for carbon pricing (tiered by income).
  • 70% of compensation goes directly to individuals—reduces risk of government capture; designed for immediate disbursement (e.g., mobile money).
  • Grand bargain would cut 120 billion tons CO2 (2025–2050), averting $28 trillion in climate damages, while delivering meaningful revenue to poorer countries.

Memorable quote:
"It's not a radical idea. If I dump garbage in your backyard, you probably want some compensation for that. Here the garbage is shorter lives and climate ills. But it's entirely voluntary—moral responsibility combined with self-interest." [43:48, Michael Greenstone]

5. Closing the Cost-Benefit Gap: Power Sector Decarbonization

Prof. Patrick Bolton (Imperial, Columbia)

• Focuses on practical, “catalytic” climate finance: high-income countries provide grants (not loans) to phase out fossil-based power in emerging markets.
• Target: $500 billion/year total for 10 years (25% from donors, 75% leveraged locally), about 0.3% GDP for a core coalition—a feasible, transformational public investment.
• Cites South Africa’s Just Energy Transition Plan: of $8.5b pledged, only 4% delivered as grants; scale and reliability are missing.

Memorable quote:
"If this leads to the decarbonization of the power sector in all emerging markets, then the benefit coalition gets in terms of lower climate damages is greater than the financial cost. It is a bargain." [54:00, Patrick Bolton]

Q&A Highlights and Panel Reflections

Importance of Political Buy-in and Trust

• Building consensus in divided societies: Without agreement on the severity of the threat (notably in the US), buy-in for finance or aggressive policy is weak. Proposals suggest “coalitions of the willing,” recognizing a Paris-style, universal deal is unlikely.
  [57:00 — Question from audience]

• Reliability and speed of finance: Skepticism persists in the Global South that money never arrives (or arrives as slow, conditional loans). Greenstone emphasizes direct, immediate, verifiable payments; Rahman remains cautious based on lived experience.
  "Because in exchange for money a lot of countries will distrust the process. The money never shows up." [77:15, Sherry Rahman]

US, China, and the Future of 'Coalitions of the Willing'

• High-level deals may need to proceed without China/US, but both could play roles—especially China, which stands to benefit from technology exports and leadership in the developing world.
  [66:00, Patrick Bolton & Robin Burgess]

Evolving Role of the COP

• Expect less consensus, more “action track” with coalitions driving breakthroughs rather than waiting for universal votes.
• Panelists stress the need for a concrete, measurable, and sustained agenda—COP should be a platform, not a one-off moment each year. [89:30, Robin Burgess]

Carbon Pricing, Mandates, and Tipping Points

• Debate over mandates or subsidies to trigger technological tipping points vs. pricing. Panel recognizes mandates have played a role in EV/solar adoption and acknowledges “all tools on deck” (not just pricing).
• Caution over political backlash (e.g., French yellow vests).

Notable Quotes

• Sherry Rahman:
  "The big flaw at the heart of this agenda is... no one can coerce anyone into staying there, meeting their targets, or providing a pledge that actually is auditable." [13:18]

• Jose Schenkman:
  "There's no evidence that green bonds earn a relevant premium. Financial engineering is not a miracle machine." [30:20]

• Michael Greenstone:
  "The only path to reducing risk from climate change runs through very large reductions in emissions from non-OECD countries." [40:12]

• Patrick Bolton:
  "Maybe that's where the promise of Belem is now—the idea that COP will deliver a unanimous agreement? Forget about it. We know the US is going to oppose every step. You have to think in terms of a coalition of the willing." [65:55]

• Robin Burgess (Chair):
  "We're moving from a multilateral, government-to-government universal solution process to a plurilateral, multi-stakeholder process where it's coalitions of the willing. And that's what we're really trying to get going here." [90:30]

Concluding Tone

While the panel exhibits clear-eyed realism—even pessimism—about the slow pace, political backsliding, and “three decades of failure,” each speaker brings forward ambitious but practical proposals, rooted in a call for transparency, mutual benefit, and coalition-building. Money and tons—finance and emission cuts—are the pivots. But the chorus of voices ensures adaptation, justice, and trust remain central to the COP’s evolving purpose.
