In recent years, nations have been promising to cut back on fossil fuel use. Cities are doing so, too. And as cities consume around 78% of global energy, that’s a good thing for reducing the world’s carbon footprint. Latin America leads with the highest number of renewably-powered cities. Brazil alone has at least 15 fully fossil fuel-free cities, and several others that are close to 100% renewable. Europe is next. But others in the U.S. and Australia have ambitious goals. Kyra Appleby, head of cities at UK-based Carbon Disclosure Project, says that the data shows that city transition to clean power will continue. “These cities understand the business case for doing so: 86% of these cities reporting actions say they see economic opportunities from efforts to tackle climate change.”
