Climate and Nature Bill

We led the campaign behind the world-leading Climate and Nature Bill, proposed legislation to put the UK’s Paris Agreement and Kunming–Montreal Global Biodiversity Framework commitments into law. The CAN Bill is supported by almost 200 cross-party MPs and over 1,200 leading scientists. It has the joined-up climate and nature crisis high on the parliamentary agenda and created one of the biggest moments of pressure in Westminster in 2025 when the Bill reached its Second Reading debate.

Wins for the campaign

The CAN Bill debate demonstrated strong cross-party consensus on the need for urgent climate and nature action. While the Bill was blocked under a rare three-line whip, reflecting the scale of support it had generated, the campaign secured important wins. These include a new annual climate and nature statement to Parliament, a DEFRA and DESNZ report, an MoU between the JNCC and the CCC, the establishment of a Production and Consumption Transformation Centre, and a Public Participation Strategy strongly shaped by our campaigning.

So, what's next?

Targets alone are no longer enough. What’s needed now is delivery, at pace and scale, to protect communities and our national security from the growing risks we face, including food insecurity, flooding, disease and instability. We remain committed to the UK’s climate and nature commitments, and cannot wait for further delay. We must act now on the science-led solutions people and nature need. The Climate and Nature Bill remains our “North Star” guiding our work as we continue to champion its core provisions through all available legislative and policy routes.
