Podcast Summary: "Valuing Nature in a Changing Climate: Rethinking Natural Capital"

LSE Public Lectures and Events — September 24, 2025
Panel: Robin Burgess (Chair), Giuliano (Climate Policy Initiative), Jim Leap (Ocean Solutions, Stanford), Rohini Pandey (Yale)
Timestamps provided as needed.

Overview

This episode, part of LSE’s Climate Week, explores how the concept of natural capital—valuing natural resources as economic assets—is being transformed by climate change, technological advances in environmental measurement, and evolving policy landscapes. The panel features leading experts discussing innovations in measuring and monetizing natural capital, from forests and oceans to carbon and biodiversity. Each speaker approaches the question from their area—terrestrial forests, oceanic ecosystems, and carbon markets—while also addressing the crucial questions of scale, political economy, and global governance.

Key Discussion Points & Insights

1. The Global Climate Challenge and Natural Capital (Larry Kramer, President of LSE)

Timestamp: 00:17–05:01

• Climate change is the "über problem"—it worsens every other global issue (political economy, immigration, democracy, etc.).
• The technical tools to address climate change now exist; the main barrier is the implementation within economic, political, and social systems.
• LSE’s new Global School of Sustainability aims to integrate resources across disciplines to tackle these interconnected challenges.
• Kramer highlights the school's commitment to interdisciplinary solutions for sustainability.

“Everything else that we’re trying to deal with in the world has the overhang of climate creating pressures on it…”
— Larry Kramer (03:00)

2. Emergence of Natural Capital Markets and Measurement (Robin Burgess, Chair)

Timestamp: 05:01–13:03

• Burgess shares a personal anecdote from Scotland: In 1996, the value of a Highland estate focused on forest restoration was static. Decades later, due to government incentives for peatland and renewable energy, its valuation skyrocketed—demonstrating how new markets for natural capital (carbon, renewables) can rapidly shift economic incentives.
• Technological advances (satellites, data analytics) have made natural capital measurable at an unprecedented global scale, especially for carbon. Biodiversity lags behind but is improving.
• Students have been the driving force behind LSE’s sustainability initiatives, highlighting the bottom-up demand for environmental economics.

“Nothing much has changed… The only real thing he gained was trees. But then you roll forward to last year. Suddenly… he gets an offer from Oxford University for £30 million.”
— Robin Burgess (06:40)

3. Measuring the Impact of Forests on Water and Energy: Flying Rivers (Giuliano, Climate Policy Initiative)

Timestamp: 13:03–24:22

• Giuliano introduces the concept of "flying rivers"—airborne moisture streams generated by Amazonian forests through evapotranspiration, affecting rainfall and water supply thousands of kilometers away.
• New econometric models use satellite wind data to trace and quantify the impact of deforestation on rainfall and hydropower far from the forest.
• Their research found major hydropower plants are heavily dependent on these flying rivers. Historic deforestation in the Amazon has already reduced Brazilian hydropower by 3,700 GWh/year (lighting almost 2 million households).
• The approach links forest degradation to concrete losses for sectors like energy, agriculture, and urban water supply, providing a powerful policy tool.

“Literally, 17 out of 20 of Brazil’s largest hydrodams are on the path of these flying rivers… 3,700 GWh lost per year due to historical deforestation.”
— Giuliano (20:11)

• Policy relevance: Quantifying these links can shift political support for forest conservation by connecting distant constituencies (energy, agriculture, urbanites) to the fate of standing forests.

4. Oceans as Vital but Overlooked Natural Capital (Jim Leap, Stanford/Ocean Solutions)

Timestamp: 24:27–36:21

• Oceans comprise 99% of Earth’s living space (by volume) and are essential for food (3 billion people), livelihoods (hundreds of millions), and climate regulation (absorbing 90% of excess heat and 25–30% of CO₂).
• Despite playing the “mother of all ecosystem services,” oceans suffer from chronic neglect in policymaking—partly due to their physical remoteness and measurement challenges.
• Oceanic “blue carbon” ecosystems (mangroves, seagrass, salt marshes) sequester 4–15x more carbon per hectare than rainforests but are much smaller in total area (50 million ha).
• Policy challenge: Elevating oceans in national priorities (beyond marginalized fisheries/oceans ministries) to ministries of finance, development, and health.
• Indonesia’s example: Integrating blue foods (fish, aquaculture) into national nutrition and development plans as a way to value and protect ocean ecosystems.

“It is literally true that if it were not for the ocean, we would already be toast.”
— Jim Leap (25:19)

“Our challenge is… how do you elevate these issues beyond the scope of the oceans minister and into the issues that are relevant to health ministers, finance ministers and prime ministers.”
— Jim Leap (30:15)

5. Towards Credible, Global Carbon Markets for Nature-Based Solutions (Rohini Pandey, Yale)

Timestamp: 36:21–51:03

• Current carbon markets operate on two models: voluntary markets (cheap, fragmented, low trust in credits’ real impact) vs. compliance markets (industrial emissions, higher prices, regulatory oversight).
• Integrating nature-based solutions (like forest conservation) into compliance markets can harness “huge gains from trade”—tropical forests can abate emissions far more cheaply than most industrial reductions.
• Critical issues:
  • “Non-additionality”—paying for forests that wouldn’t have been cut anyway undermines market effectiveness.
  • Lack of standardization and transparency in measurement.
  • Managing long-term risks (forest fires, permanence, reversals).
• Proposal: A centralized oversight institution to set universal protocols for measurement, verification, and risk mitigation (including “insurance” against natural disasters/fires). This would allow credible, tradable nature-based credits and move beyond fragmented voluntary markets.

“In the voluntary carbon market, it’s saying the average project... probably has one tenth of that much carbon being prevented. The rest of that may well be just a lot of people coming in who are not going to cut down their trees with or without the money.”
— Rohini Pandey (68:04)

6. Political Economy, Scale, and the Role of States

Panel Q&A, Timestamp: 51:03–56:46

• Transformational action on natural capital (forests, oceans, carbon markets) requires government leadership—NGOs and private actors can show the way, but only states can deliver scale.
• Effective pricing and protection of nature must involve communities, ensure just compensation, and have national governments negotiate on behalf of citizens.
• Political and technical coalitions are essential to create “market demand” for government action.

Notable Quotes on Political Economy

“It’s very hard for a single community to ever negotiate what should be the price... In the end, those negotiations are going to end up being global in nature.”
— Rohini Pandey (52:25)

“Private sector, civil society, creative coalitions… can be part of both showing the way and creating the momentum and maybe creating the political space for governments to do what we need them to do.”
— Jim Leap (53:47)

Additional Q&A: Real-World Applications & Open Challenges

- Measuring & Mitigating Rainfall Risks ("Flying Rivers")

Giuliano confirms the concept could apply to insurance markets (like Indian crop insurance) but mechanisms are context-specific and require understanding local forests and wind dynamics.
(61:13)

- Biodiversity Targets vs. “Natural Capital” Metrics

• Biodiversity, unlike carbon, is harder to capture with a single target due to its qualitative/localized nature. Combining qualitative macro-goals (e.g., CBD’s 30x30 target) with economic measurement is powerful, but markets for biodiversity as such remain contentious.
• Pricing biodiversity within existing carbon markets risks undermining the single-price clarity for carbon; separate mechanisms are preferable.

- Voluntary Carbon Market Shortcomings and Solutions

Problems:

• Huge price gap: Voluntary credits ~$7/ton vs. EU ETS ~$77/ton; reflects doubts about the real additionality and verification of voluntary credits.
• Fragmented protocols, lack of transparency. Solutions:
• Centralized protocols, transparent measurement, risk pooling, and unified compliance markets.

- Global South Challenges: Building Capacity for Natural Capital

Solutions:

• Leverage proliferation of open-access satellite data.
• International development banks (World Bank, ADB) are investing in technical support and capacity-building for natural capital accounting, aiming to foster “sovereign capacity” rather than dependence.
  (74:10–75:24)

- Declining Carbon Sink of Tropical Forests

• Climate impacts already eroding forest carbon capacity; risk models and payment mechanisms must reflect new realities and include resilience/insurance mechanisms.

- Centralized Oversight for Compliance and Enforcement

• Envisioned as a phased, multi-level system: national regulators run domestic compliance markets, with a credible, central institution ensuring standardization and interconnection.
  (83:20)

- Concerns about Commodification & Overuse

Some audience and panel concerns: Does treating nature as capital risk repeating cycles of exploitation? Panel response:
Valuing nature creates the incentives and visibility needed to protect it—abstraction and invisibility have not worked. Still, market and governance design must ensure long-term stewardship, not short-term exploitation.
(82:01–83:20)

“My only counter to that is, okay, do we think we’re going to win by just pretending there’s nothing there?”
— Jim Leap (82:47)

Concluding Reflections

Robin Burgess (Closing, 87:20–89:02):

• Climate solutions will require “whatever it takes”—global collaboration, innovative finance, credible markets, attention to measurement, and leveraging political will at all levels.
• Gains from trade (especially globally integrated carbon and natural capital markets) and social innovations (e.g., Bangladesh’s climate protections) are providing new hope and possibilities for scaling up solutions.
