"The rules are fine", and net zero "has" to happen". So in your mind there's no room for argument and the objective is sacred. So how many guns are you willing to put to peoples' heads to get them to change their diets? To get them to stop flying? Driving in particular is required for many peoples' livelihoods, particularly those on the lower end of the socioeconomic spectrum.
IMO, the truly "hard" part of getting to net zero is getting people like you to realize you're not going to force your proposed solutions onto the rest of the world. You're going to have to team up with people you don't like. You know why Texas, the oil/petrochemical capital of the US, has so much wind power? It isn't because an army of environmentalists descended on the state house shouting slogans and waving signs, it isn't to save the environment, it isn't to stop climate change. It's because wind energy is cheap in Texas, something that appeals to even the most coal-rolling, roundup-spraying, green-lawn-in-the-desert Texan.
If you want to save the environment, drop the moralizing and meet people where they are. Until that happens environmentalism is just going to produce backlash, that allow the environmental movements feel even more superior and do things to produce even more backlash, until the price of meat, power, transportation and housing goes up so much that you get a backlash that undoes any short-term progress that was made.
