I strongly disagree. Reducing warming to <=2C will take drastic government regulations. It's never going to happen. This isn't something that can be done by recycling campaigns or "work remote!" slogans.
The ineffectiveness of slogans is irrelevant. If you want to prove my statement wrong, point to a viable political party with a plan that drastically reduces commuting. Then I'll agree that all other political parties are obstacles.
