Existing city commitments alone could reduce emissions by a total of 13 GtCO2e by 2050

New research by the parties to the Compact of Mayors, along with research partner Arup, indicates that existing city commitments alone could reduce annual emissions by 454 Megatons CO2e in 2020 -- a total of 13 Gigatons CO2e by 2050.

The research was conducted by C40 Cities Climate Leadership Group (C40) and Arup, in partnership with ICLEI-Local Governments for Sustainability (ICLEI), United Cities and Local Governments (UCLG), UN Habitat, the UN Secretary- General’s Special Envoy for Cities and Climate Change and the World Resources Institute. Cities were selected from key global city sustainability network champions, including C40, UCLG and ICLEI to assess the existing public commitments that cities have voluntarily made to reduce their GHG emissions in order to catalyze more ambitious climate commitments.

GHG reduction commitments matter because they drive action and further investment in cites. City governments with emissions reduction targets report three times as many emissions reduction activities as cities without targets. By demonstrating the impact of cities’ climate commitments on a global scale, this report is a first step in delivering the vision of the global Compact of Mayors, the world’s largest effort for cities to tackle climate change. The Compact will enable cities to publicly commit to deep GHG emissions reductions, make public existing targets and plans, and report on their progress annually, using a newly-standardized measurement system that is compatible with existing protocols.

The report’s key findings, including cumulative reductions of 13 GtCO2e in 2050, reveal that city commitments are having an impact now. And, there are opportunities for greater commitments across more cities globally.
