Finally, some reporting of what the current level is Vs 1990 levels.

UK greenhouse gas emissions have fallen by almost half from 1990 levels, mainly due to the phaseout of coal from electricity generation.

So another ⅓ to go, in ten years. For that to happen we need to see announcements of plans very soon. The easy changes have already been made / are in progress for the grid. Manufacturing and industrial transport are the next big targets by my reckoning. Electrification of goods transportation would be a huge win.
