If it can make your day a little happier: I change car/gsm/whatever when they die and can't be repaired anymore (my PC is 13 years old for example, it's alittle too weak for rust-analyze, but well :-))). I haven't taken a plane in 20 years; use the train when possible. I buy online less than once a year. I don't have a swimming pool.

But I'm not involved in politics, so I don't spend much time on helping others to change. And my house's insulation is not good (old house).

Depending on where you live and how you heat your house, fixing this one thing might be more effective at reducing emissions than everything else you’re doing combined.

Would paying for such upgrades for people who cannot afford them be considered cost effective carbon dioxide removal?

[master-lincoln]

no, because it does not remove carbon dioxide, but prevent future emissions.

Isn't the net result the same? Is it better to pay (for example) $500 to remove a tonne of CO2 from the atmosphere, or to pay $100 to prevent the same amount of CO2 from being emitted in the first place?

If CO2 removal costs us more than emissions reduction technologies, isn't it a false economy?
