A person's carbon footprint is approximately proportional to the amount of stuff they consume, measured in dollars. Getting into the weeds on what's more or less carbon intensive and other details is just a way to evade living like someone much poorer than you are. Look around and see if there are people who live on half your income. If there are, then you could too, if you really cared.

If you can't help spending all you make, maybe you could start by getting a new job that pays much less than your old one...

That won't save the planet, but it is the way to do your part.
