Ed Miliband is to explicitly call out politicians who reject net zero policies for betraying future generations in an unprecedented update to parliament about the state of the climate crisis, which he is calling “an exercise in radical truth-telling”. With Reform UK proposing to scrap all net zero measures and even questioning the science behind climate change, and the Conservatives ditching environmental targets, Miliband hopes to regain the initiative with a stark warning to MPs. Reform has pledged to scrap all net zero policies and subsidies for renewable energy. The Conservatives, who put into law the commitment to reach net zero by 2050 under Theresa May, abandoned the target this year. But with polls showing a majority of Britons back current net zero policies, Miliband said this was a dangerous falsehood.
