To answer this question you have to look at the basic pathways which are interesting although outside the scope of this project.
If we want to decarbonise 100% – we can achieve say 17% of that with carbon capture (in that 17% of carbon emissions are from electricity consumption).
What we do beyond that is well known – heating homes and running cars with electricity (which can be generated carbon free in many ways) rather than gas or gasoline – and running planes, ships and cars on hydrogen power – and also reducing consumption.
The zero emission scenario is actually quite easy to imagine – and achievable today, if people were willing to pay for it!
The difficulty is getting from here to there – finding ways to move society to more zero carbon and doing it gradually so that people can absorb the price rises slowly. Also doing it in a way which can be driven by politicians without politicians looking to their voters like they are increasing the cost of their driving. This is what this project addresses.
