“Now is our opportunity to make the agreement, a global collaboration platform.”

Christiana Figueres,
Former Executive Secretary of UNFCCC



Recognizing that the fight against climate change must include the “bottom-up” commitment of all stakeholders:

  • Local, regional and national governments,
  • Businesses and the private sector
  • Financial institutions, civil society and NGOs
  • Academia and research
  • Intergovernmental organizations and the international community
  • Key sectors impacted by climate change include health, energy, water and agriculture

We are determined to communicate the tangible contributions of sub-national governments and of their partners in order to encourage the Parties to overcome current obstacles and avoid any further delays in adopting bold measures to tackle the challenges of climate change.


Recognizing that tackling climate change is a great opportunity for sustainable development if it is associated with the expansion of a low carbon economy from the “bottom-up”. This is most effective at:

  • The local and sub-national
  • Civil society, and business level
  • Promoting the creation of new green jobs and improving the health of citizens,
  • Developing appropriate technologies
  • Increasing renewable energy production with better energy security and energy efficiency


Recognizing that the development of a low carbon economy must be delivered through the implementation of concrete projects at the local level, as well as at national policy level in the field of:

  • Renewable energies, energy security and energy efficiency
  • Transportation and mobility
  • Waste management,
  • Food security
  • Other related economic sectors.

R20 Charter

The R20 — Regions of Climate Action Charter
November 16, 2010.

WHEREAS, there is an urgent need to advance a new green economy by mobilizing clean technologies, climate resilient innovation and green investing in the financial sector, including through public-private partnerships;

WHEREAS, the delay in reaching a new binding international agreement on climate change creates both a responsibility and an opportunity for all stakeholders to tackle climate change in new and creative ways, and reinforces the importance of sustained efforts to achieve a global agreement;

WHEREAS, each day lost increases the costs of stabilizing greenhouse gas emissions levels to avoid dangerous interference with the climate system, and diminishes the adaptive capacities of the most vulnerable societies and populations;

WHEREAS, addressing these issues requires an unprecedented level of cooperation and collaboration, especially between subnational governments in developed and developing countries from around the world;

WHEREAS, the United Nations Development Programme (UNDP), United Nations Environment Programme (UNEP), United Nations Framework Convention on Climate Change and other international bodies, such as the Organization for Economic Cooperation and Development and International Energy Agency, have recognized that subnational governments play a key role in rising to the climate challenge and are responsible for the majority of the actions required to halt climate change as well as to adapt to its impacts;

WHEREAS, the mission of the R20 is to develop and implement low-carbon and climate-resilient projects through cooperation among developed and developing country subnational governments, non-governmental organizations, corporations and educational institutions.

Through these efforts, the R20 demonstrates both the capacity and willingness of these entities to tackle climate change and create strong green and climate-resilient economies;

WHEREAS, the R20 will achieve its mission by:

  • Catalyzing partnerships between regions for fast track actions, especially in energy efficiency, renewable energy and clean transportation;
  • Mobilizing and leveraging technology, public funding and private-sector finance where appropriate; and
  • Aiming to reach the objectives of the territorial approach to climate change in partnership with UNDP, UNEP and other UN agencies and associations of regions.

WHEREAS, in so doing, the R20 will show that 75 percent of global greenhouse gas emissions reductions needed by 2020 to limit the increase in world average temperature to 2 degrees Celsius can be achieved at no net cost, that many projects will generate new economic benefits, and that promoting climate resilience and adaptation will similarly result in significant cost saving and generate economic benefits and opportunities;

NOW THEREFORE, in furtherance of the goals and principles of the 2008 and 2009 Global Climate Solution Declarations signed at the Governors’ Global Climate Summit in Los Angeles, California, we hereby pledge our support to the mission of the R20.
