The "One Planet Summit" was held in Paris on December 12 on the initiative of President Emmanuel Macron. In partnership with the UN and the World Bank, the aim was to review progress on current action against climate change, two years after the adoption of the Paris Agreement. In the attendance of many international leaders, the pioneering action of cities was reaffirmed during the round table "Accelerating Local and Regional Action for Climate", co-hosted by Anne Hidalgo, Mayor of Paris, and Miguel Arias Cañete, European Commissioner for Energy and representative of the Global Covenant of Mayors for Climate & Energy.
On this occasion, the "One Planet Charter" was launched by the C40, the Global Covenant and ICLEI (Local Governments for Sustainability), three networks of local governments committed against climate change. With this Charter, cities will have the opportunity to engage in actions that boost investment, sustainable public procurements and policy decisions for renewable energy and energy efficiency. The charter will support cities to increase the supply of sustainable infrastructures, while working with national governments and the private sector to mobilize all in favor of climate action.
