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.
