Why join ICLEI?

Take the next step towards a sustainable future by becoming an ICLEI Member.

What it means to be an ICLEI Member

ICLEI Members are at the heart of our network. They steer the direction of our work, shape our strategy and play a central role in our governance structure. All our Members are fully committed to sustainable urban development.



Joining ICLEI means connecting to more than 1,500 local and regional governments and gaining access to technical experts and a diverse community of partners, from businesses to financial institutions to intergovernmental bodies. Through these connections, ICLEI Members have access to fresh and innovative ideas and solutions from around the world. They work closely alongside ICLEI experts, benefiting from up-to-date information and expertise on anything from global sustainability policy to practical technical solutions.

There are plenty of opportunities for Members to get involved and show their leadership. By joining ICLEI, Members are eligible to vote and take part in our network-wide governing bodies. Members can also host an ICLEI office and global or regional events to showcase their on-the-ground efforts to other Members, experts, implementing partners and media. By participating in our activities, ICLEI Members also serve as role models to other cities around the world.

ICLEI Members actively engage with their peers through conferences, workshops, webinars and online platforms. They have access to grant and travel funding that provide hands-on learning opportunities and networking. ICLEI Members attend global events, Members-only gatherings and governance meetings, with access to travel funds available to ICLEI Members, with specific consideration for those from the Global South.

ICLEI Members are showcased in our wide-reaching global communication channels, like our global newsletter or CityTalk blog, and have preferential access to speaking slots at ICLEI events and high level global fora where they represent the interests of local and regional governments. We also feature good practice examples from our Members in webinars  and publications
