Example given, an average level of attributable CO2-emission of 2 t/year should be realized in the sustainable economic community: This would determine that persons who match this level pay the assigned suggested retail price like today - let’s say 50 cent for a pack of pasta. 

One with a level of 20 t/year might pay maybe 2,50 dollar for the same pasta in the same shop, and primitive people with nearly zero attributable environmental impact would have a subsidized purchasing power and pay only 10 cents. Thus, companies would loose initially turn over as their clients would have less purchasing power than before. But on the other hand they would win new customers.

Companies would push products with less attributable environmental impact since people would demand them to keep their net purchasing power high.
