You can if you take the politics out of it and not set stupid dates that cannot be met so you look good. Building a whole smash of clean nuclear powerplants would instantly solve all of our problems but that isn't allowed either. However doing that means we can build electric cars or run electric trains or buses of whatever kind and not have to worry about the electricity for them coming from bad environmental means. It is the green mob and Corbyn's lot in the end that will drag us down because they are dead against the above. They are in favour of more sustainability and sustainability always actually means restraint, good luck to him on selling that one. The Paris climate thing is the start because it is okay to set arbitrary dates on things but it is another to completely push the burden of fixing it onto someone else. Another runway is also absolutely vital at Heathrow because air travel is one of the fastest growing industries there is, they are dead against that as well. Total lunatics.
