Older people may remember the push to make your house more energy efficient. So, seems you have a choice, higher energy bills or higher indoors C02.

So what is needed, move off fossil fuels. I remember seeing during the covid lockdown, C02 Levels did not raise for the first time in decades and I think they may have fell a little. That is because auto traffic decreased a lot. Right now I believe we are on our way to +2.5C :(

Apart from disease transmission, since I've gotten a CO2 monitor in my apartment I've noticed that running the gas stove or oven for even a little while will make a huge spike in CO2.
