A carbon tax would change behavior in short order. The challenge is introducing then maintaining it; people can always vote it out. I think left-leaning jurisdictions should definitely give it a try.
Carbon taxes are massively regressive. There is no political coalition that simultaneously wants to act against climate change and doesn’t mind driving further income inequality.
You can’t have it both ways. You can’t have one comment talk about consumption being the root of all ill, then another comment stating that reducing consumption is regressive.
the challenge in carbon tax isn't the people who vote it out, it's the people who never vote it in in the country next door (or on the other side of the world, it hardly matters)
