The Climate Briefing

At COP30, Parties agreed to develop a 'Just Transition Mechanism', which many hailed as one of the real bright spots of the conference. Climate Action Network International, for example,  called  the decision 'one of the strongest rights-based outcomes in the history of the UN climate negotiations'.   What is the Just Transition Mechanism? What impact could it have? And what are the next steps in...

Attention is increasingly turning to artificial intelligence as its capabilities and influence permeate nearly every sector.  AI's growth raises important questions about its environmental footprint; risks associated with future scale, and how such a globalised industry can be effectively governed.   This episode of the Climate Briefing explores: Where are we today in terms of AI capability and us...

All eyes are currently on the Gulf due to the US–Israel conflict with Iran and the disruptions around the Strait of Hormuz. In this two-part series, the Climate Briefing co-hosts and their guests take a deep dive into the region, which plays a crucial role in the global supply of oil and gas. The first part of the series (released on 21 April) delved into the history of the region, addressing ques...

Today's 'take–make–dispose' economy operates in a linear way: resources are extracted, turned into products, used, and then discarded — with severe consequences for the climate and environment. Transitioning to a circular economy means replacing this system with one that keeps materials in circulation through reuse, repair, remanufacturing, and recycling. But what needs to happen — both internatio...

All eyes are currently on the Gulf due to the US-Israel war with Iran and the disruptions around the Strait of Hormuz. In this two-part series, the Climate Briefing co-hosts and their guests take a deep dive into the region, which plays a crucial role in the global supply of oil and gas. How did the Gulf countries become such dominant fossil fuel exporters? What has this dominance meant for their...

As the conflict in the Middle East rattles energy markets, this episode explores the connections between climate change, energy, and geopolitics. It addresses questions such as:   What does the war in Iran reveal about the links between fossil fuels, vulnerability, and power? What lessons can be drawn? What does the energy transition mean for global geopolitics, and how should governments manage t...

China is the world's largest emitter and dominates global production of green technology. A few days ago, the National People's Congress approved the country's 15th Five-Year Plan, China's main economic and policy blueprint for the period 2026–2030. What does the new plan say about China's climate and clean tech ambitions? And what does it reveal about China's broader geopolitical and foreign poli...

What are the most important changes the Paris Agreement has brought about? How should the COP process evolve? And why does geoengineering need to be approached with caution?   The fourth part of the Future of Climate Diplomacy mini-series features a fascinating conversation between Chatham House's Chris Aylett (standing in for Anna and Bhargabi) and Laurence Tubiana, CEO of the European Climate Fo...

The race to secure critical raw materials is turning attention towards an unlikely place: the ocean floor. In this episode, Anna speaks with Dr Isaac Kardon (Senior Fellow at the Carnegie Endowment for International Peace) and Meredith Schwartz (Associate Fellow at the Centre for Strategic and International Studies) about the geopolitics of deep-sea mining.

The EU has introduced a Carbon Border Adjustment Mechanism (CBAM) to prevent carbon leakage – when companies move production to countries with weaker climate rules, or when EU products are replaced by more carbon-intensive imports. But the measure has sparked controversy and concern, especially among countries in the Global South, as seen during COP30 in Belém. This episode of the Climate Briefing...

Exactly one year has passed since President Trump returned to the White House. How has the first year of Trump 2.0 impacted global efforts to address climate change, and what might happen going forward? To discuss this, Anna and Bhargabi are joined by Gina McCarthy (former US National Climate Advisor, former EPA Administrator and Chair of the America Is All In Coalition).

In the final episode of the year, Anna speaks to Professor Tim Lenton (Chair in Climate Change and Earth System Science at the University of Exeter) about climate tipping points – the thresholds where a tiny change could lead to large and often irreversible transformations in the Earth system, with potentially disastrous consequences. Examples of such 'negative' tipping points include the dieback...

COP30 in Belém is over. What happened at the conference? What were the main outcomes? And what needs to happen next?   To find out, Anna speaks to Jennifer Morgan (Senior Fellow at the Fletcher School of Law and Diplomacy at Tufts University; Fellow at the Hertie School of Governance; and former State Secretary and Special Envoy for International Climate Action at the German Federal Foreign Office...

COP30 is about to begin. Where do we stand ahead of the conference? What are the key issues to watch, and how might the complex geopolitical context influence the discussions in Belém? To find out, Anna is joined by three Chatham House colleagues: Ana Yang (Director of the Environment and Society Centre), Bernice Lee (Distinguished Fellow and Senior Advisor) and Nick Bridge (Associate Fellow at Ch...

The incoming COP30 host, Brazil, has signalled it wants COP30 to mark the moment the UNFCCC transitions to a 'post-negotiation' phase, and that efforts should focus on action and implementation going forward. As part of its work to make this a reality, Brazil is reforming the UNFCCC's 'Action Agenda', a process bringing together cities, regions, businesses, investors, civil society and governments...

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 AII...

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 in...

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...

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 Res...

On the 23 rd 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 thi...

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...

What happened at the 4 th 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...

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.   I...

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 L...

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 3 rd UN Ocean Conference , Anna speaks to Ambassador Peter Thomson (the UN Secretary-General's Special Envoy for th...
