Executive Summary

The Under2 Coalition is a global community of ambitious sub-national governments publicly committed to long-term deep decarbonization and supporting the Paris Agreement’s climate goal of keeping the rise in global average temperature well below 2oC.

The Coalition brings together signatories of the Under2 MOU (Memorandum of Understanding), a commitment by governments to limit their greenhouse gas emissions by 80 to 95% below 1990 levels, or to 2 annual metric tons of carbon dioxide-equivalent per capita, by 2050.

The Under2 Coalition is an initiative primarily driven by state, regional and provincial governments. However, jurisdictions at all levels of government are encouraged to sign or endorse the Under2 MOU, thus committing to deep decarbonization in their jurisdictions. Signatories include over 200 states, provinces, regions and cities, as well as national government endorsers. Together they represent almost 40 percent of the global economy.

The Climate Group acts as the Secretariat for the Coalition.

Our History

The Under2 Coalition was created on May 19, 2015 with 12 founding signatories. It originated from a partnership between California and Baden-Württemberg with the aim of bringing together ambitious states and regions willing to make a number of key commitments toward emissions reduction and to help galvanize action at the COP 21 (Conference of the Parties) Paris Climate Change Conference in December 2015.

Since its inception, it has grown substantially, including subnational signatories and national endorsers. Please click the link to view a full list of Under2 Coalition members.

The Under2 Coalition…

  • Brings together subnational governments willing to commit to either reducing their greenhouse gas emissions 80 to 95 percent below 1990 levels or limiting emissions to less than 2 metric tons per capita by 2050;
  • Is in line with scientifically established emissions levels necessary to limit global warming below 2 degrees Celsius;
  • Offers opportunities for states, regions, and cities to share ideas and best practices on how to reduce greenhouse gases and expand renewable energy development;
  • Provides a model for other governments of all levels to join;
  • Brings international attention to the actions and ambitious reduction goals of climate leaders at a subnational level around the globe;
  • Demonstrates the collective impact of these actions and commitments across states, regions, cities, and countries; and
  • Highlights the diversity of approaches to reducing emissions.
