“Raising Global Level of Ambition Through Local Climate Action”
  • “In this 25 years of global climate regime, there is one overpowering message: no President, Minister, Mayor, CEO or citizen can meet the challenge of climate change alone. If we are to bring down global temperatures, we must step up, scale up, speed up local climate action globally. Together, let’s innovate, integrate, collaborate!”
    Park Won-Soon, Mayor, Seoul Metropolitan Government, Republic of Korea; Chair, World Mayors Council on Climate Change, at the Climate Summit 2014

  • The "Mexico City Pact" sends a key signal to the negotiations that it can indeed be done, and that millions, if not billions, of people around the world are ready to begin implementing climate change action. Many other cities and local and regional administrations can be inspired to take action and to report to carbonn Cities Climate Registry.“  
    Christiana Figueres, Executive Secretary, UN Climate Change Secretariat

  • “Local government is where the rubber hits the road when it comes to responding to the human impacts of climate change. We fully support funding for cities, towns and municipalities for their registered adaptation actions.”
    Margareta Wahlström, The Special Representative of the UN Secretary General for Disaster Risk Reduction, welcoming the Durban Adaptation Charter

  • “The designated central repository of the Compact of Mayors, the carbonn Climate Registry, will enable the compilation of data through existing national, regional, global city reporting platforms. The carbonn Climate Registry represents the ultimate level of our collective efforts.”
    Jürgen Nimptsch, Mayor of Bonn, at the Climate Summit 2014
