Letters: The futility of net zero

Not zero

Sir: I was delighted to see your leading article about the impossibility of net zero (‘Carbon candour’, 22 March). We need now to expose its futility. The UK’s efforts will make no difference at all to global temperature. Whether it is naturally occurring or produced through coal burning, there is not the slightest chance of stopping the rise in atmospheric carbon dioxide (not ‘carbon’, which is nasty black stuff).
