I'm glad they're approaching it in a way beyond just "make everything more expensive". It's interesting how when it comes to climate change, a lot of the same people who are otherwise committed to egalitarian ideals immediately jump to "just charge more" as a solution for everything. I'm not saying those kind of policies can't be a piece of the solution, but I really don't see it being effective to tell all but the rich to bike to work and take on vegan diets and give up out of town vacations and stop using a/c, etc. Sure that would probably be effective, but expecting that level of asceticism out of people is just going to push them into the arms of the political parties who tell them "climate change is fake, so take that vacation and don't worry".
