What we do

ICLEI works at multiple scales, building connections across local, regional, national and global actors and policies. We create systems change, developing integrated solutions along five interconnected development pathways that transform urban areas. 

ICLEI experts are on the ground, working alongside local and regional governments to anticipate and respond to complex challenges, from urbanization and climate change to ecosystem degradation and inequity. We invest in the capacity and knowledge needed to design solutions to these challenges and make decisions informed by data, scientific evidence and local realities and pressures. 

ICLEI leads knowledge exchange and sparks city-to-city and city-to-region connections worldwide. Peer exchange and capacity building are at the heart of what we do.  

At the national and global scales, we push for robust policies that reflect the interests of local and regional governments and apply global policy to sustainable urban development strategies at the subnational level.

ICLEI forms strategic alliances with international organizations, national governments, academic and financial institutions, civil society and the private sector. We create space for innovation and lead our partners to build new ways to support sustainable development at the urban scale.

The 100% RE Cities and Regions Network

The 100% RE Cities and Regions Network supports local and regional governments to commit to and deliver on 100 percent renewable energy targets by bringing networking, peer learning, technical guidance and the latest renewable energy research and findings to participants. To get involved, local and regional governments need to either approve a 100 percent renewable energy target in at least one sector or have a clear interest in exploring a target for their jurisdiction.

Transformative Actions Program

ICLEI calls for local and regional governments worldwide to develop transformative, finance-ready projects by submitting their transformative climate projects to the Transformative Actions Program (TAP). The TAP catalyzes capital flows for low emission and climate-resilient development, while providing support to local and regional governments to develop climate project concepts into low risk, high feasibility, high impact sustainable infrastructure projects.
