Annual city-wide emissions for more than 100 global cities. Includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

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.

Cities are responsible for 75% of global greenhouse gas emissions. The transition to a sustainable economy will be won or lost in our cities. Explore how cities across the globe are working to measure their city-wide emissions, a vital first step towards taking ambitious climate action.
