A Memorandum of Understanding between the EU Covenant of Mayors and the World Alliance for Efficient Solutions was signed on 16 November 2017 during the EU Energy Day conference in Bonn, in the margins of the COP 23 UN Climate Change Conference hosted by Fiji and Germany. The two organisations chose to strengthen bilateral cooperation in areas of common interest, notably in clean, smart, efficient and renewable energy technologies, related societal innovation and low carbon development. Eckart Würzner, Mayor of Heidelberg and Member of the Covenant Political Board, and Bertrand Piccard, Initiator and President of the Solar Impulse Foundation and Chairman of the WAES, signed the Memorandum. By bridging local and regional authorities willing to develop and implement technological innovations and pilot projects on the one side, and innovative entrepreneurs on the other, this partnership will bring forward solutions that create cleaner, more sustainable and more liveable environments for citizens and their deployment at local level. Background The European Covenant of Mayors for Climate & Energy brings together more than 7600 local and regional authorities voluntarily committed to implementing EU energy and climate objectives on their territory. The European Covenant of Mayors has been initiated and is supported by the European Commission. The World Alliance for Efficient Solutions aims at federating actors in the field in clean technologies and shed light on existing efficient solutions to fast-track their implementation.
