Fourteen charity funders have pledged to implement policies to help combat climate change.
The Barrow Cadbury Trust, the Esmée Fairbairn Foundation, the Joseph Rowntree Charitable Trust and the Paul Hamlyn Foundation are among the organisations that have signed the Funder Commitment, which promises they will take action on climate change and commit to reporting publicly on their progress.
The commitment says charity funders have a key role to play in ensuring money is distributed in a way that recognises and seeks to combat climate change.
All the signatories have pledged to look at how they can use their investments, operations and funding programmes to contribute to a post-carbon economy, the commitment says.
Moira Sinclair, chief executive of the Paul Hamlyn Foundation, said: "We increasingly feel that we need to respond more to climate change, especially given our grant-making focus on young people and the degree to which they see this as the defining challenge of their generation.
"We are already taking action in some areas, but in others we know that we have a long way to go, so we welcome the framework and stretch target that being a signatory to the Funder Commitment on climate change will create.
"Staff and trustee engagement will help as we shape our response, and we look forward to reporting on our progress next year."
Nick Perks, coordinator of the Funder Commitment and former trust secretary at the Joseph Rowntree Charitable Trust, said: "Like the British public as a whole, people in charity funders want to see bold, positive action on climate change.
"This Funder Commitment gives a framework for all funders, whatever their mission, to play their part. We hope that many more funders will sign up in the coming months."
The other signatories are: the environmental funder Arcadia, the Frederick Mulder Foundation, the Friends Provident Foundation, the Gower Street Foundation, the JA Clark Trust, the Lankelly Chase Foundation, the Local Trust, the Solberga Foundation, Thirty Percy and Zennström Philanthropies.
