The government has been ordered to redraft its net zero plan for a second time, after a High Court judged ruled it not fit for purpose. Environmental campaigners argued that former energy secretary Grant Shapps signed off the government's Carbon Budget Delivery Plan without evidence it could be achieved and gave key policies the green light without even looking at the assessments of the risks surrounding them. A High Court judge has upheld the campaigners’ claim and ruled that the government must now redraft the plan again, providing more details about how it intends to meet its legally-binding emissions targets.
