Making less CO2 is a good aim for other reasons, anyway.

Why? As CO2 rises plants grow better and crop yields increase.


One reason is that the stuff we burn to make CO2 now is the stuff we may
well want as feedstock to make other chemicals more easily in the future.

that is almost a red herring.

Burning fossil fuel for energy stops when it takes more energy to get it
out of the ground than yu get from burning it.

There will still be billions of tonnes left to make plastic bags with.

More expensive, yes.

And there is another tipping point. If diesel were - say - £10- a litre,
you could make it for less using off peak nuclear electricity out of
..ahem..water, and carbon dioxide.
