Nature groups prepared to ‘mobilise’ 20m members over UK climate policy

Organisations including RSPB, National Trust and RSPCA urge prime minister to honour green promises

Environmental groups claiming to represent 20 million people will mobilise their members if UK ministers water down climate commitments, they have warned.

Groups including the RSPB, National Trust and the RSPCA have written to the prime minister, Rishi Sunak, who has signalled his willingness to back away from green policies should the Conservatives stand to benefit from it electorally.
