The most efficient way to solve climate change is to provide every user in the planet the exact amount of goods/services that solves a user's need at the exact time.

This eliminates all the redundant transportation, housing, waste (food, cloths, electronics, equipment)

And the only way to provide is that through tracking (both history and intent).

No, the most efficient way to solve climate change is for people to consume less crap; this reduces far more wasted resources. There is no need to give up your privacy and no need for corrupt middlemen to track you.
