Mate, don't fall for the Tufton St propaganda. It is not expensive and not difficult.

Imagine the UK was a person who currently emits 100kg of CO2 per year.

32kg comes from heat. A bit of insulation retrofit plus switching to heat pumps saves 24kg

28kg comes from driving. Changing from petrol/deisel to EV saves 21kg

23kg comes from Electricity generation. Changing to 100% renewable/nuclear saves 23kg... and saves the remaining 15kg HP and EV emissions.

Wow: we have saved 83 out of 100!

What's left?

2kg from industry: steel, cement etc. Carbon capture and concrete alternatives maybe save 1kg.

13kg from farming. If you stop eating meat you *save 5kg

(*not really: I will come back to this)

And if you stop eating entirely you save 8kg.😉

Now the interesting thing about this is the big 3 - which together save 83% - either cost less than the status quo in TCO terms (EVs) or levelized cost per KWh terms (Renewables) or only need a decent market size (HPs) to become cost neutral.

The remaining dribs and drabs will no doubt drop too, with a greener grid and Electric Tractors and emissions-focussed industrial processes.

And as for th 5kg for meat eating... it is bullshit - literally.

It is based on methane emissions. But these GHG's are not like fossil

fuel. As long as there are no more cows here today than 30 years ago the 30 year old farts are breaking down at the same rate as todays ones are emitted.

So have a burger. But no more than 30 years ago.
