The London mayor and chair of a global alliance of cities announces $1bn for electric buses
Global cities are acting now to fight the climate crisis, while many governments are delaying, the London mayor, Sadiq Khan, has told the Cop26 summit.
Cities are growing fast and cause an estimated 75% of carbon emissions, making urban action critical to halting global heating. Khan is chair of the C40 group of 97 major cities, representing more than 700 million people and a quarter of the global economy.
