I agree wholeheartedly with all of this. But I think reducing consumption is probably the most significant thing a person can do to lower their CO2 footprint. My rule of thumb (which is fairly good across a surprising range of goods for ones that I've tested) is that at least 500g of CO2 is emitted for every dollar you spend, whether that's on electricity with our current typical fuel mix or on a cheeseburger or a plane journey. So if your electricity bill is say 5% of your monthly expenditures, electric energy usage is just responsible for 5% of your total CO2 emissions. This is very ballpark, but you get the idea.
