About Us

R20 – Regions of Climate Action is a not-for-profit international organization founded in 2011 by former Governor of California Arnold Schwarzenegger in cooperation with a number of leading regions and NGO’s, the United Nations, Development Banks, Clean-Tech companies, and Academia. Our mission is to accelerate sub-national infrastructure investments in the green economy to meaningfully contribute to the Sustainable Development Goals (SDGs). Our vision for the future involves inclusive, resilient, and low-carbon societies.

Through collaboration with and support from the Leonardo DiCaprio Foundation and our partners, we have created a technical and financial ecosystem (R20 Value Chain), which facilitates the identification, structuring, development, and financing of sub-national green infrastructure projects.

Our Mission

To accelerate sub-national infrastructure investments in the green economy.

At R20 – Regions of Climate Action, we believe that cities and regions play a central role in the fight against climate change and its impact. In particular, we believe that local and regional actors are uniquely positioned to implement the transition to a low-carbon green economy, whereby natural resources are conserved, fossil fuel use is limited, public health is protected and enhanced, while societies promote equality.

Our efforts are designed to support sub-national governments around the world to develop and finance low-carbon and climate resilient infrastructure projects in the fields of renewable energy, energy efficient lighting and waste optimisation. Although local authorities are at the center of our work, we recognize that fast-tracking the transition to inclusive, resilient and low-carbon societies requires greater mobilization and collaboration between a wide range of stakeholders.

Our approach aims to “connect the dots” and foster understanding and interconnection between policy-makers, clean technology providers and public-private investors throughout the whole project development value chain.

From Action to Transaction.

We are structuring all our programs and projects in line with our value chain approach, 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 efficient lighting.

We are seeking to enable the implementation of at least 200 infrastructure projects worth 5 billion USD of CAPEX by 2025, making it business as usual by then.

R20 Staff and Offices

Headquartered in Geneva, Switzerland, we benefit from a unique concentration of International Organizations, Financial institutions, NGOs and Academia that we can work with to further our mission.

To facilitate and bring together local authorities, technology providers and investors, we work closely with our regional offices installed around the world.

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.
