USA emits almost 8 times more C02 when compared to India per capita. https://ourworldindata.org/grapher/co-emissions-per-capita

In that sense India would need to be 10B+ people to poluate as much as US / west does.

Except per capita co2 emissions AND total emissions have been falling in the USA.

China now emits more co2 than europe and USA combined. And this is NOT because of exports to the west, those are now also falling yet co2 emissions are still climbing.

This is what I mean. Just these two countries like india and china are emitting so much CO2, that any reduction in emissions by the west by not eating steak just won't matter. Either you stop china doing this (good luck!) or think of another solution.

Again these studies don't take into account things like burning, air pollution, waterways pollution, nor trees per capita in India vs North America.

If you've got enough trees per person to offset their carbon use, then it doesn't matter how much co2 they emit.
