The 2021 United Nations Climate Change Conference (COP26), is the 26th time the UN countries have met to discuss climate change. Yes, there have been 25 previous conferences that have debated what to do and yet little progress has been made. We need firm, binding actions, not just words, so what should Britain, as host of the November conference in Glasgow, put on the agenda to ensure that actions with impact are agreed and delivered? UK Government Cabinet member Alok Sharma is President of COP26, Christiana Figueres is a founder of the Global Optimism group, was head of the UN climate change convention when the Paris agreement was achieved in 2015 and is co-author of The Future We Choose: The Stubborn Optimist's Guide to the Climate Crisis. Patricia Espinosa is the Executive Secretary of the Secretariat of the United Nations Framework Convention on Climate Change. They are in conversation with Peter Lacy, author of Waste to Wealth: The Circular Economy Advantage ​and The Circular Economy Handbook.
