The underlying point is that any fix needs to be (as) insensitive (as possible) to population levels, since they will rise and wipe out any emissions cuts achieved by 'hairshirt' lifestyle changes. (I read somewhere that a westerner becoming vegetarian actually has very little impact on their CO2 emissions anyway).

A bigger deal than population increase is that energy use is going to rise massively with just the population we have, as people move out of energy poverty.

We need to make the energy zero-carbon.
