How can the AIIB help deliver on the new climate finance goal?

The multilateral development banks (MDBs) play a critical role in addressing climate change and have a key role to play in delivering on the ‘New Collective Quantified Goal’ on climate finance, agreed at COP29. This Climate Briefing episode focuses on the newest of the MDBs: the Asian Infrastructure Investment Bank (AIIB), launched in 2016. What are the similarities and differences between the AIIB and the other MDBs? What is the AIIB doing to address climate change?  To find out, Anna and Bhargabi speak to Kim-See Lim (Chief Investment Officer, Public Sector (Region 1) & Financial Institutions and Funds (Global) Clients at the AIIB) and Hans Peter Lankes (Managing Director and Deputy Chief Executive at the Overseas Development Institute; Visiting Professor in Practice at the LSE Grantham Research Institute; and a Senior Fellow at the LSE/Oxford International Growth Centre).  In the introduction to the episode, Anna and Bhargabi speak about growth trends in global renewable energy generation, climate politics in the UK, the US-China trade spat and the ratification of the High Seas Treaty.

Forests play a critical role in the fight against climate change. With COP30 taking place in the Amazon, addressing deforestation is likely to be a topic of high priority at the meeting. But what can actually be achieved? To find out, Anna and Bhargabi speak to Mauricio Voivodic, Executive Director of WWF-Brazil, and Edward Davey, Head of the UK Office of the World Resources Institute. In their introduction to the episode, Anna and Bhargabi speak about key developments at the opening of the 80th Session of the UN General Assembly (UNGA) and New York Climate Week.  

Trump 2.0 poses a huge challenge for the renewable energy industry in the US. Not only has the administration rescinded environmental incentives and regulations with bearing on future projects, it has also in various ways delayed and/or obstructed offshore wind projects already under construction (like the Empire Wind and the Revolution Wind projects). What does all of this mean for the renewable energy industry in the US? What does it mean for US competitiveness and the global energy transition? In the introduction, Anna is also joined by Chris Aylett, a Research Fellow at Chatham House's Environment and Society Centre, to discuss some of the main climate stories in the run-up to COP30. To find out, Bhargabi speaks to Ben Backwell, CEO of the Global Wind Energy Council, a member-based organisation that represents over 1,500 companies, organisations and institutions in over 80 countries.

In this third instalment of the Future of Climate Diplomacy mini-series, Climate Briefing hosts Anna and Bhargabi explore what lessons that can be drawn from the history of the climate negotiations and how this can inform the future of climate diplomacy. To do this, they are joined by long-time COP researcher Dr Joanna Depledge (Research Fellow at the Centre for Environment, Energy and Natural Resource Governance and at Centre for Science and Policy, both at the University of Cambridge).   This week’s Climate Briefing also includes a chat with Dr Patrick Schröder (Senior Research Fellow at Chatham House’s Environment and Society Centre), who explains why the negotiations on a global plastics treaty are important and why the recent round of talks, once again, ended with no deal.   To find out more about the plastics treaty negotiations, see this piece in Foreign Policy by Patrick Schröder.   And to find out more about the proposal to introduce a voting rule at COP, see this piece by Dr Joanna Depledge.

On the 23rd of July 2025, the International Court of Justice (ICJ) issued its long-awaited Advisory Opinion on the obligations of states in respect to climate change. The Advisory Opinion makes clear that states have far-reaching obligations under international law to prevent harm to the climate system and that breaching such obligations could result in having to make reparations, among other things.   So, what impact might the ICJ’s ruling have on international climate diplomacy and action, including climate-related litigation? To find out, Anna and Bhargabi speak to Dr Margaretha Wiwerinke-Singh, who is an Associate Professor of Sustainability Law at the University of Amsterdam and who lead the legal team of Vanuatu and the Melanesian Spearhead Group throughout the ICJ proceedings, and Dr Maria Antonia Tigre, who is the Director of Global Climate Change Litigation at the Sabin Centre at Columbia University.   To learn more about the ICJ’s Advisory Opinion, read this Chatham House expert comment and/or listen to this Climate Briefing interview with Ralph Regenvanu, who at the time of the interview served as Vanuatu’s Minister of Climate Change Adaptation, Meteorology and Geo-Hazards, Energy, Environment and Disaster Risk Management.

Ahead of the landmark COP30 in Belem, Brazil, this November, calls for reform of the UNFCCC and COPs are growing, as are concerns that the only formal global forum for climate negotiation and cooperation is under threat. In a series of conversations, Anna, Ruth and Bhargabi interview thought leaders in the climate world about what the future of climate diplomacy should look like. The second guest in this mini-series is Kaveh Guilanpour, Vice President for International Strategies at C2ES, former lead of the UK’s UNFCCC negotiations, co-lead negotiator for the EU, co-lead negotiator for the Alliance of Small Island States, and head of secretariat for the High Ambition Coalition, and senior advisor to the UNDG’s Climate Action Team.

What happened at the 4th International Conference on Financing for Development (FFD4) and what does it mean for climate action? What are ‘solidarity levies’ and how might they help close the climate finance gap? What is needed to ensure someone actually reads the ‘Baku to Belém Roadmap to 1.3T’ after COP30? To find answers to these and other burning climate finance-related questions, Anna speaks to Joe Thwaites (Senior Advocate, International Climate Finance, Natural Resources Defense Council) and Tom Evans (Senior Associate, Global Solidarity Levies Task Force).   To learn more about climate finance, please see these Chatham House outputs: ‘Closing the climate finance gap: How to raise the money the world needs to support climate action’ (research paper, available here) ‘Taxing high-emitting sectors could help pay for climate-induced loss and damage’ (expert comment, available here).

The 2025 edition of the June climate meetings in Bonn (formally ‘the sixty-second sessions of the Subsidiary Body for Scientific and Technological Advice and the Subsidiary Body for Implementation of the UNFCCC’, or ‘SB62’) took place 16 to 26 June. These meetings, which take place every year, constitute the only formal space for negotiations ahead of the COP, and are therefore very important.   In this episode of the Climate Briefing, Anna and Ruth speak to Alden Meyer (Senior Associate at E3G) and Catherine Abreu (Director of the International Climate Politics Hub) about what the main outcomes of the conference were, what the key sticking points were, and what it all means for COP30.

Climate litigation is both a strategic tool for climate action and an increasingly common part of the litigation landscape. Recent legal rulings have huge potential implications for the accountability and financial liability of big emitters, including both corporations and national governments.   Anna and Ruth talk to Joana Setzer, climate litigation and global environmental governance expert at London School of Economics’ Grantham Research Institute. Joana explains the growth in climate litigation, describes landmark cases and tells us what we might expect from climate litigation in the future.

From plastic pollution to overfishing and climate change: the ocean is facing many severe threats. Sustainable Development Goal (SDG) 14 is focused on conserving and sustainably using the ocean and its resources. But what progress has been made in implementing this goal? Ahead of the 3rd UN Ocean Conference, Anna speaks to Ambassador Peter Thomson (the UN Secretary-General’s Special Envoy for the Ocean) about the state of the ocean, progress made in implementing SDG14, key next steps, and the potential of the UN conference to accelerate action.
