Who are we?

The Climate Coalition brings together over 130 organisations with a combined reach of 22 million people - working together to build public support and drive action on climate and nature across the UK.

We provide the infrastructure, campaigns and connections that help organisations - from grassroots groups to major charities, businesses and faith organisations - turn public support into real-world change at scale.

Membership is not just about joining a network. It’s about being part of a cross-sector coalition that shapes national campaigns, engages communities, and strengthens the movement for change.

Why Join?

As a member, your organisation can:

1. Shape national campaigns and policy

Contribute to high-profile flagship campaigns like Great Big Green Week and Show The Love, and help shape coalition priorities — ensuring your organisation’s voice influences collective action.

2. Build partnerships and learn from across the sector

Work alongside a diverse network of organisations, share insight, and collaborate through working groups and member spaces.

3. Reach and engage the public at scale

Take part in campaigns that engage millions across the UK, helping you reach new audiences, deepen engagement, and maximise your impact.

4. Access tools, insight, and support

Use campaign resources, the Local Intelligence Hub, sector insights, and support from the coalition secretariat.

5. Increase your visibility and profile

Showcase your work across the coalition and and connect with new audiences across the UK.

Together, this means your organisation can achieve more reach, more connection, and more influence than working alone.

Membership is open to UK-based organisations committed to climate and nature action.

A coalition powered by participation

The strength of The Climate Coalition comes from the organisations within it.

Our impact grows when members take part - contributing ideas, sharing expertise, and collaborating during key moments.

This shared effort is what enables us to achieve more together than any organisation could alone.
