About Us

R20 – Regions of Climate Action is a not-for-profit international organization founded in 2011 by the former Governor of California, Arnold Schwarzenegger, in cooperation with a number of leading Regions, the United Nations, Development Banks, Clean-Tech companies, Academia and a number of NGO’s, to support sub-national governments around the world to develop and finance green infrastructure projects.

R20, with its partners and the support of the Leonardo DiCaprio Foundation, has created a unique value chain and financial ecosystem that facilitates the identification, structuring, development, and financing of sub-national green infrastructure projects. R20 essentially acts as a liaison manager between sub-national authorities, technology providers and public-private investors, harnessing the best expertise that is available the length of the project development value chain to deliver explicit results in line with the Paris Climate Agreement and the Sustainable Development Goals (SDGs).

R20 Mission

To help sub-national governments around the world to develop and communicate low-carbon and climate resilient economic development projects.

The ideal pipeline of clean energy projects is not currently happening, even though intergovernmental bodies, national governments, sub-national governments, NGOs, academics, technology providers, public and private financial partners share the same vision and want concrete action. This is due to a number of factors:

  • national and sub-national politicians lack awareness of the long-term political, technical and financial solutions for a sustainable safe, clean economy;
  • project developers do not know how to identify, design and communicate the right information to project investors;
  • project investors are not sure how low-carbon investments fit into their existing investment instruments and portfolios.

The R20 works towards addressing these factors in order to help build an effective green deal flow at sub-national level. This is made possible by connecting Regions, Technology and Finance to build sustainable low-carbon projects.


 Vision: From Milions to Billions.

Going forward, R20 is structuring all its programs and projects in line with its unique value chain, and working with all R20 members and partners to scale the identification, development and financing of green infrastructure projects in the field of waste management, renewable energy and energy efficiency.

R20 is seeking to enable the implementation of at least 100 infrastructure projects with 3 billion USD worthy CAPEX by 2020, and make it business as usual by 2025.

R20 is comprised of R20 Regions of Climate Action Association and R20 Foundation, which work as two complimentary entities. The former carries out day-to-day operational duties, and the latter manages important investment decisions.


The R20 Foundation is the entity responsible for almost all aspects of funding of the R20 Association and its operations. Its objective is to drive the financial vision and the implementation of bankable portfolios of low carbon and climate resilient sub-national infrastructure projects.

The R20 Foundation was created at the request of a number of investors interested to invest in the R20 ecosystem of blended finance. With a Board of Directors composed of green finance leaders, the R20 Foundation meets the demands of development banks, sovereign funds, private bans, private equities, family offices and pension funds.

During his tenure as Governor of the State of California from 2003 to 2011, Arnold Schwarzenegger was responsible for signing into law groundbreaking legislation that translated the Kyoto Protocol into Californian law. This and other initiatives is what led President Obama to ask Governor Schwarzenegger to obtain similar commitments from thirty other US States.

A. Schwarzenegger’s success in implementing action at the sub-national level, and his ability to demonstrate the potential to scale this impact by replication at the sub-national level is ultimately what gave birth to the R20 Regions of Climate Action.

In December 2009, after evaluating the failure of the COP15 to agree on the practical means to limit carbon emissions, Gov. Schwarzenegger, with the support from the UN Secretary General Ban Ki Moon, decided to create a new coalition of Regions committed to action. He met with a number of heads of regions, including Governor Uduaghan from Delta State, Nigeria, President Charet from the Province of Quebec, Canada, President Huchon and Vice President Michèle Sabban from Region Ile de France, and 17 other representatives from other Regions, who all decided to create R20 Regions of Climate Action.

In September 2010, Governor Schwarzenegger organized the Third Global Governors Climate Summit in Sacramento and launched the R20 Charter, which was signed by representatives of Regions, national governments, NGOs, foundations, private companies and finance institutions. In September 2011, the First constitutive General Assembly of R20 marked the official creation of the NGO. Linda Adam, The California Environmental Protection Agency State Secretary, was officially elected President of the R20 Board and Terry Tamminen was nominated as R20 Special Advisor to Governor Schwarzenegger, the Honorary Founding Chair of R20.

In January 2012, Dr. Christophe Nuttall, Director of the UNDP Hub for Innovative Partnership, officially joined R20 as Executive Director.

From 2013 to 2017, Michèle Sabban took on the R20 presidency.

In June 2017, Magnus Berntsson, President of the Regional Council of Västra Götaland and President of AER, was elected as the new R20 president.
