The UK has long considered itself to be at the forefront of climate legislation and aspiration. It was the first to introduce legally binding commitments on emissions reductions, with the Climate Change Act 2008. It was also the first to make a legislative commitment to Net Zero. There is no question, however, that its aspiration and commitment have long outpaced delivery. What is more, there are very worrying signs that, in this critical decade of delivery, we are stalling or even going backwards.
