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?
