COP26

The starting gun has fired on COP26, and the UK now has less than two weeks to get around 200 countries over the line towards stronger commitments on climate action. It's not going to be easy. Of the 25 COPs that have gone before, only one produced concrete targets for change. That was the 2015 Paris climate conference - aka COP21 - where two new ideas were launched onto the international stage: keeping average global temperature rises below 1.5C, and the notion of aiming for 'net zero'. Women were at the forefront of the Paris negotiations and we unite three of those women in a Woman's Hour COP special - Laurence Tubiana, France's Climate Change Ambassador and Special Representative for COP21 - who many recognise as the main architect of the Paris Agreement; Amber Rudd, Secretary of State for Energy and Climate Change at the time of Paris and the then leader of the UK's COP21 negotiating team; and Jennifer Morgan, one of a group of women who brought the idea of Net Zero to the global stage during Paris. She is now Executive Director of Greenpeace International. They discuss women's role in Paris's success, the origin story of net zero, the successes and failings of global governments in delivering on their promises, and their hopes for COP26 bringing about necessary change.
