Under2 Coalition

The Under2 Coalition is driven by a group of ambitious state and regional governments committed to keeping global temperature rises to under 2°C.

The coalition is made up of more than 220 governments who represent over 1.3 billion people and 43% of the global economy.

The Climate Group is the Secretariat to the Under2 Coalition and works with governments to accelerate climate action through three workstreams.


Deep decarbonization pathway planning: supporting governments to develop robust medium and long-term (2050) emissions reduction plans in line with the goals of the Paris Climate Agreement.


Scaling innovative policy solutions: spreading today’s best climate policies and developing new policies to ensure full decarbonization.


Mainstreaming transparency: supporting governments so they have the expertise and systems in place to assess their emissions accurately, track progress and ensure policies remain fit for delivering against climate targets.

Established in 2015, the Under2 Coalition builds on the legacy of its forerunner, the States & Regions Alliance.

The Under2 Coalition brings together over 220 governments, spanning six continents and 43 countries committing to reduce their GHG emissions toward net-zero by 2050.

Signatories also submit a plan that outlines their unique set of actions to reach their reduction goals and commit to cooperative efforts around the implementation and monitoring of action to meet these goals.

The Under2 Coalition provides a global forum for sub-national governments to work together to get on a trajectory consistent with 2050 carbon neutrality. The Under2 Coalition sets the tone for bold climate leadership and provides an effective global partnership model for parties to the UNFCCC. We are sending a clear signal that net-zero by 2050 is achievable, desirable and leads to faster results.

Together they represent over 1.3 billion people and a collective GDP of US$34 trillion, representing 43% of the global economy.
