Cities house half the world’s population but represent almost two-thirds of global energy demand and 70% of carbon emissions from the energy sector. Therefore, our cities have a vital role to play in the transition to a sustainable economy. And across the world, cities are already taking action. Explore which cities have ambitious action to cut emissions and reduce their climate impact.
