The fastest thing that we can do to get emissions down is to improve the efficiency with which we use energy, and in particular the way in which we provide heat in buildings. So that’s not really a question of people having to change their lifestyles so much as us investing, as a nation, in the infrastructure of our buildings, so that we actually get energy bills down as well as getting emissions down, and making life just as comfortable for everybody then as it is now.
