More than 40 countries have committed to move away from coal, in pledges made at the COP26 climate summit. Major coal-using countries including Poland, Vietnam and Chile are among those to make the commitment. But some of the world's biggest coal-dependent countries, including China and the US, did not sign up. We'll discuss how significant this pledge is, and how important coal is around the world.

Also, we'll discuss 'fast fashion' - the cheap mass production of garments, and the habit of wearing clothes only few times before discarding them. This can contribute to greenhouse gas levels, cause water and air pollution, and create a lot of waste. So what is the alternative? We'll speak to three people across the world who have created their own 'sustainable fashion' businesses.

And every day we're joined by a health expert to answer questions from around the world on Covid-19. Today our guest is Dr Emma Hodcroft, molecular epidemiologist at the University of Bern in Switzerland.
