So the problem is people buying shit? Not that manufacturing shit is causing the massive amount of carbon emissions?

I vote it's the manufacturing. What you just said was "China et. al. are not culpable for horrible environmental practices, the people on the other side of the world are because they buy dogshit products"

I can say with 100% certainty that china can manufacture dogshit products in an environmentally friendly way... which would drive the cost up and people would in fact not buy them.

You're blaming the wrong entity here.
