Under2 Coalition

The Under2 Coalition is a coalition of subnational governments that aims to achieve greenhouse gases emissions mitigation. It started as a memorandum of understanding, which was signed by twelve founding jurisdictions on May 19, 2015 in Sacramento, California. Although it was originally called the Under2 MOU, it became known as the Under2 Coalition in 2017. As of June 2024, the coalition represents 178 individual states, regions, provinces and subnational governments along with several other national and subnational entities. The list of signatories has grown to 270 governments, representing over 1.75 billion people and 50% of the world economy. The Under2 MOU was conceived through a partnership between the governments of California and Baden-Wurttemberg, with Climate Group acting as secretariat.
