Cities are the front lines of the climate crisis. Home to more than half the world’s 7.8 billion people, they generate 70% of global carbon emissions. They’re also hot spots for the development of transformative climate solutions. Since 2011, WWF’s One Planet City Challenge has helped more than 400 cities demonstrate leadership and accountability by reporting climate targets and action plans. Participating cities receive expert guidance, tools, and support from WWF and partners. Take a tour of some standouts to see what they’ve done.
