A carbon tax would be the most efficient ways to reducing CO2 emissions. It's a far simpler system than trying to work out average average emissions for different fleets of vehicles, never mind trying to balance competing CO2 production coming from various industries, agriculture and transportation. Complicated laws make for loopholes and massive inefficiencies as technology and the economy changes. We should tax precisely the thing we want to reduce. This is assuming you're actually on board with mainstream science and the problems associated with anthropogenic climate change. If you think climate change is a hoax or harmless, then yeah any carbon tax is a drain on the economy with no upside. We are barely getting by as it is. Okay, that's the problem. People need more equitable access to opportunity and a stronger safety net. Better public or charter schools, or more earned income tax credits or a higher minimum wage or maybe even straight up UBI. All of these are things that might address poverty more effectively than repealing smog laws.
