Under2 Coalition

The Under2 Coalition – for which The Climate Group acts as Secretariat – is the world’s premier sub-national government climate action network. It is led by state and regional governments committed to supporting the efforts of nations and delivering the goals of the Paris Agreement, to keep global temperature rises to below 2 degrees Celsius.

The Under2 Coalition brings together over 200 signatories and endorsers, spanning six continents and 43 countries committing to reduce their greenhouse gas (GHG) emissions by 2050. Together they represent over 1.3 billion people and a collective GDP of US$30 trillion, representing almost 40% of the global economy.

Led by states and regions internationally, the Coalition brings together signatories and endorsers of the Under2 MOU, a commitment to limit GHG emissions by 80-95% on 1990 levels, or to two metric tons of carbon dioxide equivalent per capita annually, by 2050. Established in 2015, the Under2 Coalition builds on the legacy of its forerunner, the States & Regions Alliance.

The Under2 Coalition brings together over 200 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$30 trillion, representing almost 40% of the global economy.

The Climate Group is Secretariat to the Under2 Coalition and works with governments to accelerate climate action through three work streams:


Deep decarbonization pathway planning: supporting governments to develop robust medium and long-term (2050) emissions reduction plans in line with the Paris Climate Agreement goal of keeping the rise in global temperature well below 2 degrees Celsius of warming.


Scaling innovative policy solutions: replicating and spreading today’s best policies to accelerate climate action, and developing new policies to ensure full decarbonization over the longer-term.


Mainstreaming transparency and reporting: 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 decarbonization targets.


Thank you for your interest in joining the Under2 Coalition. 

The Under2 MOU (Memorandum of Understanding) is a commitment driven by state, regional and provincial governments to reduce their GHG emissions towards net-zero by 2050. Central to this is the public commitment by all signatories to reduce their GHG emissions by 80 to 95% below 1990 levels, or to 2 annual metric tons of carbon dioxide-equivalent per capita, by 2050. However, jurisdictions at all levels of government are encouraged to sign or endorse the Under2 MOU, thus committing to deep decarbonization in their jurisdictions. Please view a full list of members below.

Under2 Coalition signatories and endorsers are categorized as follows:


  • ‘State and regional government signatories’ refers to jurisdictions that are one level below national governments, including states, regions, and provinces.
  • ‘City and local government signatories’ refers to cities, counties, and all administrative divisions below state and regional level.


  •  Typically refers to national governments that wish to support the goals of the Under2 Coalition.

The Under2 Coalition is led by a diverse group of Co-Chairs and supported by a steering group, to ensure the Coalition is truly diverse and globally representative.


The work of the Under2 Coalition is driven by our Co-Chairs, which represent and promote our collective vision and goals. Our Co-Chairs are:

A new governance and leadership structure was agreed in 2017, to enables a stronger voice for states and regions in the global climate agenda, better recognition for sub-national climate leadership, greater impact across different levels of government and increased support and resources to member governments. Incumbent Steering Group members and Co-chairs of the States & Regions Alliance will steer the work of the Under2 Coalition for the coming year until new elections in 2018.

Steering Group members for 2018:

  • Australian Capital Territory
  • Baden-Württemberg
  • Basque Country
  • Brittany
  • California
  • Catalonia*
  • Jalisco
  • KwaZulu-Nata
  • Lombardy

*President of the Government of Catalonia was the elected Co-chair for Europe and due to the current political situation in Catalonia, the Minister-President of Baden-Württemberg is proposed by the Steering Group to take on the European Co-chair role on an interim basis.

*President of the Government of South Australia was the elected Co-chair for Asia-Pacific until 17 March 2018.

Under2 Global Ambassador: Christiana Figueres, former Executive Secretary of the UNFCCC and Convenor of Mission 2020. The Global Ambassador helps to raise the awareness of the Coalition’s ambitions globally.
