Recognizing that cities play an important role in leading the way to achieve carbon neutrality in the second half of this century, namely the goals of the Paris Agreement, ICLEI supports cities and regions laying out their vision on a sustainable society in 2050. The declaration lays out a vision for cities leading up to 2050 and encourages cities around the world to join Kyoto in cultivating a culture of sustainable cities that is in balance with the local and global environment.

Rising global energy use remains a major challenge, with cities and regions being central players in making energy more secure, clean and sustainable. To transform from a linear to a circular economy there is a growing need to take advantage of renewable resources, including energy. ICLEI supports the cities and regions initiatives aiming at 100% Renewable Energy. Since 2007, ICLEI has offered an international forum for discussion and exchange among policymakers and practitioners from various levels of government, energy experts, energy services providers, researchers and business representatives.

Responding to the Fijian COP23 Presidency call, in its capacity as focal point of the Local Governments and Municipal Authorities (LGMA) constituency at the UNFCCC, ICLEI worked with UN-Habitat and the Global Covenant of Mayors for Climate and Energy to mobilize Cities and Regions Talanoa Dialogues in 2018. The aim was to enable discussion between different levels of government on scaling up climate action.
