COP30: The UK must support an ambitious outcome on just transition

CAN-UK and more than 45 charities, campaigns and trade unions have called today for the UK to champion an ambitious outcome on just transition at COP30.

We are calling for a Belém Action Mechanism #BAM to be agreed at COP30 to embed fairness and a focus on better lives for everyone into climate action at home and overseas.

The UNFCCC’s Just Transition Work Programme offers a vital route to make the vision of fair, rights-based global climate action real, and COP30 in Belém presents a unique opportunity to move beyond negotiations and rhetoric to deliver a concrete outcome that will:

  • Advance international co-operation by providing the technical and financial support necessary for countries and communities to undertake ambitious climate action in line with science.
  • Guarantee meaningful participation of workers, communities, Indigenous Peoples, women, youth and other affected groups. The people most affected must be at the heart of climate action to deliver fair outcomes and better lives.
  • Make climate action fair by protecting people’s rights
