Sure, I try to do that, and then I realise that just one US state is burning off millions of dollars worth of natural gas per day[0] , purely because it's too cheap to make it worth capturing. Or I go back to my home country and see people burning rubbish and mud coal and realise I can't breathe in winter and the snow is black/grayish.

So you know, at some point you think to yourself - why would I stop driving my Euro 6-compliant, modern, very efficient car, that is extremely heavily taxed to offset pollution, to make....what difference? I know if a million other people made the same choice it would make a difference, but it's the same as telling someone who is already leading a very considerate, very heavily taxed lifestyle that they should do their part too, while their neighbour is clearly burning plastic in their front yard, and no one cares.

It's a weird one, because I don't want to say "it's ok for me to pollute a little bit, because there are people who pollute lots", but damn, it is super hard to justify making life even more expensive for myself.
