Normal people have much less choice than you imagine.
Even in the rich western world, only the very affluent can buy electric car instead of gas one. Only the very affluent can afford apartments in city centers so they can walk instead of driving. Nobody can change where their electricity comes from, whether is it coal or renewables. Nobody can pick between grocery store that gets its supply in diesel trucks and second grocery store that gets its supply on electric trucks and trains powered by renewable electricity. There's no "planet non-destroying iphone" next to "planet destroying iphone" in the shop for you to decide between.
