Compact of Mayors
The Compact of Mayors is the world’s largest cooperative effort among mayors and city officials to reduce greenhouse gas emissions and climate risks in cities.
By establishing a common platform to capture the impact of cities’ collective actions through standardized measurement of emissions and climate risk, and consistent, public reporting of their efforts, it provides hard evidence that cities are true climate leaders, and that local action can have a significant global impact.
On 22 June 2016, the Compact of Mayors and the Covenant of Mayors announced the new Global Covenant of Mayors for Climate and Energy, a newly merged initiative to bring these two efforts together. See C40 blog for more details of the announcement.
To be fully compliant with the Compact of Mayors, cities commit to taking action in three phases, with requirements covering both climate mitigation and adaptation. The status of each committed C40 city can be explored in the dashboard below, along with all city-reported data. More details on the requirements can be found here.

Cities use a single standard for developing greenhouse gas inventories; the Global Protocol for Community-Scale Greenhouse Gas Emissions Inventories (GPC). CURB is an official decision support tool of the Compact of Mayors designed to support the setting of emission reduction targets and the development of climate action plans.
