CLIMATE activists have vowed to launch a new campaign of civil resistance if Britain’s next PM fails to sever reliance on fossil fuels.

Just Stop Oil has delivered letters to the leaders of all major parties ahead of the election on July 4 demanding they commit to signing a fossil fuel non-proliferation treaty, which would halt expansion and manage a just transition.

The Labour Party promised last month it would end new domestic oil and gas developments upon election.

Energy Secretary Grant Shapps said the plans were an “ideological vendetta against British energy independence.” 

Just Stop Oil welcomed Labour’s commitment but said it will not be enough to prevent ongoing collapse, with fossil fuel projects still being built around the world.

They said: “It is clear that continuing to extract and burn fossil fuels in 2024 is nothing short of an act of war against humanity. “

The group warned that if the incoming leader does not establish a legally binding treaty to stop fossil fuel extraction by 2030, they would launch a “campaign of civil resistance,” co-ordinated with movements in Austria, Canada, Norway, the Netherlands and Switzerland.
