Climate Cymru

Climate Cymru brings together over 400 organisations — from major NGOs to community groups, faith organisations, and businesses — united by the demand for urgent climate action through the Senedd. Its scale makes it one of the largest civil society coalitions in Welsh history.

Climate Cymru's mobilisation of 400+ organisations for the 2026 Senedd election represents the most significant civil society engagement with a devolved election since the 1997 referendum campaign. By channelling this enormous coalition's energy toward the Senedd rather than Westminster, Climate Cymru makes a powerful statement about where climate action in Wales should be decided. The coalition's 'clean and just transition' framing connects environmental policy to social justice, arguing that decarbonisation must benefit Welsh communities rather than simply extracting value from Welsh natural resources — an argument that dovetails with the Crown Estate devolution campaign. The sheer breadth of the coalition (encompassing organisations from across the political spectrum and every sector of Welsh civil society) demonstrates that engagement with devolved governance is no longer a niche political activity but a mainstream mode of democratic participation in Wales.
