As searing heat sweeps the country for the second time this year, the devastating physical reality of the climate crisis is laying bare the political cowardice of the establishment. Amid these extreme temperatures, Green party leader Zack Polanski has issued a powerful warning to Andy Burnham, the man widely tipped to be the UK’s next prime minister: backsliding on climate justice will relegate the Labour party to political obscurity. Polanski urged Burnham to reject half measures, stating that any retreat from robust environmental commitments would represent a profound moral and political failure.

The battle lines within the labor movement are now clearly drawn. On one side, progressive trade unions and climate advocates are demanding an immediate halt to the exploitation of the North Sea. The leader of Unison, the UK's largest union, has boldly called for an end to all new oil and gas drilling, recognizing that the long-term survival of working-class communities depends on a rapid transition to clean energy. This stance is supported by the Fire Brigades Union, whose general secretary, Steve Wright, pointed out that his members are already on the frontlines of the crisis, battling unprecedented wildfires fueled by rising global temperatures.

Yet, a regressive alliance of fossil fuel lobbyists, business groups, and right-wing union officials is fighting to lock the UK into decades of further ecological destruction. Sharon Graham, the leader of Unite, has aligned herself with corporate interests by backing new drilling operations. In a move that shocked progressives, Graham attacked Energy Secretary Ed Miliband’s net-zero commitments, calling them a "noose around the neck" of job creation. This corporate-friendly rhetoric has been eagerly adopted by the British Chambers of Commerce, which is demanding that Burnham exploit every remaining drop of oil in the dwindling North Sea basin under the guise of protecting jobs.

However, the argument that fossil fuels protect workers is a proven myth. Activists and industry critics point out that despite previous governments handing out hundreds of new drilling licences, employment in the sector has actually collapsed. Over the past decade, the number of jobs supported by the industry has more than halved, plummeting from 441,000 to 214,000. The reality is that corporations are automating jobs and pocketing profits while draining the basin, which is already 90% to 93% depleted of its viable reserves.

The struggle over the UK's environmental future is also playing out as an intense factional war over who will control the Treasury. Right-wing elements within Labour and the union hierarchy are actively campaigning to install former health secretary Wes Streeting as chancellor over Ed Miliband. Streeting has openly championed fossil fuel expansion, including giving the green light to the controversial and massive Rosebank oilfield.
