Bill Gates wants a huge carbon tax

"There's no doubt today if you tried to make hydrocarbons illegal that the voters would rebel against that. They like driving to work, there's a variety of practical things and there is a demand there. The ideal is that you set a carbon tax that's the size as what it takes to do direct air capture...Whenever voters are tested like in France, you put on a diesel tax, well they say: "Those people in the city are richer than me, they somehow should pay for this." In Germany when you say: "Ok, we're gonna make you buy electric heat pumps", they back off from it. If you try to do climate things brute force, you'll sometimes get people to say: "Hey, I like climate, I'm for climate but I don't want to bear that cost and reduce my standard of living."
I believe we should spend a lot of money on climate change, I believe we should have very high carbon taxes. The political realities are such that without innovation it's unlikely, particularly middle income countries that the brute force approach will be successful."
