I suggest we take money from anyone who wants to pollute. At source. Yes, some poor people will be impacted (though not as many as continuing to ignore the problem).

By "at source", I mean that car makers should not be taxed.

Instead, fossil fuels should be taxed as close as possible to when they are pulled from the ground. Not when they are used (like a car does).

Then if car makers decide to build big diesel chugging vehicles, of course their market will be severely limited because not many people will want to pay the cost of running them.

Car makers are therefore still incentivized by market forces. to build efficient vehicles, but we don't need artificial and easily gamed regimes about what proportion of their production is fuel efficient.
