You'll recall #RishiSunak's weakening of carbon targets lead to a collapse in the 'market' for carbon emissions offsets; the price is now half that within the EU (having previously been at rough parity).

So, the fact that the EU is about to bring in a #carbontax regime at the border that requires importers to pay the difference between their local offset price & the EU price, will both add costs to exporters into the EU & also mean the EU gets the tax not the UK!

Another Sunak own-goal!
