Most emissions are caused by rich people. Quite frankly as soon as you forget about the car, the rest is rather cheap. Solar panels powering a home are not crazily expensive and organic food staples are also not that much more expensive then the conventional competition. Electric cars are expensive, but the proper choice is to try to live car free anyway. A bicycle is cheap after all.

Anybody who actually is emitting more then the global average can live in a way that massivly reduces their emissions and afford to do it. Not to zero, but to a point, where it is absolutly reasitic to demand companies and governments to push for the rest.
