Boris Johnson’s climate credibility at stake in run-up to Cop26 summit

Campaigners fear net zero strategy is being hamstrung by Rishi Sunak, who refuses to provide adequate funding

Boris Johnson faces a significant test of his leadership before the Cop26 climate summit as the chancellor and business secretary are at war over the imminent plan for reaching net zero carbon dioxide emissions.

The government is poised to publish its long-awaited net zero strategy on Monday, setting out how the UK will meet its targets to cut CO₂ emissions by 78% by 2035 and reach net zero by 2050. This will also include the heat and buildings strategy for insulating draughty homes and phasing out gas boilers, along with a massive expansion of offshore wind, and building electric vehicle charging networks.
