I'd be hard pressed to find it again, but I remember watching a video years ago talking about the issue of buying new ovens for poor Africans in villages not actually working to reduce carbon as intended because what ended up happening is that they would just use now two stoves, the old one and new one, at the same time instead of tossing the old one and only using the new one. Great in theory and a seemingly easy low-hanging fruit, but may fall apart in practice, unfortunately.

Yes, we need that too.

This happens a lot in climate policy discussions - "what about this other solution?" The answer is always "yes, that too!"
