This week’s CER podcast features speakers from our recent economics conference on ‘The politics of climate change’ at Ditchley Park. Panellists included Suzi Kerr of the Environmental Defence Fund, the European Commission’s Arianna Vanini, Beata Javorcik of the European Bank for Reconstruction and Development and the World Bank’s Stéphane Hallegate, whose remarks we included in the first half of this episode. They spoke about whether we needed tougher measures against laggard countries in the fight against climate change. They also discussed whether carbon border adjustment mechanisms would work, and how developing countries could be brought on board. In the second half of the podcast, Rosie Giorgi asked her CER colleagues Elisabetta Cornago and John Springford for their takes on CBAMs, climate clubs and more.
