The problem is that people are starting from wildly variable positions. An old person on a fixed income can’t afford to replace their heating, add insulation, etc. quickly unless we have programs to help them; a rich guy who thinks gas is better for cooking or heating up his outdoor dining will blow off the minor increase; etc.
The problem is that we wasted 3+ decades on denialism and a lot of pollution comes from things with long service lives. A high-pollution SUV will be polluting in 2040, maybe 2050; a gas or oil heater might run into 2070. At this point we need more than gradual nudges — things like requiring special permits to buy new fossil fuel-burning equipment with heavy subsidies and 0% loans for installing electric alternatives.
