The UK’s incoming prime minister Andy Burnham has remained tight-lipped on his views on climate change during his leadership campaign.

When asked his views on reversing Labour’s manifesto pledge to stop new North Sea drilling in June – a move that the oil-and-gas industry and right-wing media have pushed for in recent months – he said he had “something of an open mind” on the issue.

But a trawl of Burnham’s past comments about climate change, net-zero and fossil fuels reveals a different picture.

Just a year ago in June 2025, Burnham, while mayor of Greater Manchester, gave his support to the fossil fuel treaty – a proposed international pact on phasing out coal, oil and gas – calling it a “lifeline” that “all governments” should join.

In a video message endorsing the treaty, he also said that “there should be no turning away from net-zero”.
