Within a given area rich people tend to use more carbon. Poor people are less likely to be taking international flights, etc.
Annoyingly, one big problem is that we've allowed NIMBY's to make it illegal to build homes near jobs, so people who can't afford homes near work are often stuck driving long distances to work through no fault of their own.
Rich people can afford electric cars while poor people won’t be able to, even if the car is used, through the next decade. If anything, SUV prices will drop like a rock…
Also, rich people can decide to pay for expensive upgrades to their homes (switching to heatpumps, upgrading electrical wiring for efficient solar/wind usage, solar panels, high voltage chargers for electrical vehicles), while poorer home owners (many of whom are on fixed income), aren’t able to do those things.
We agree, this is why I am not a huge fan of subsidies for EV's. Among other things, we should be encouraging fewer cars of all sorts. I do like ebike subsidies though, and better public transport.
Similarly, it can make sense to help people improve their home's efficiency, and in some places grants are available for this (insulation, etc.). Though in many cases you're using renters' taxes to make the homeowner wealthier, which isn't really fair.
