You are right about how carbon credits work. But, first CO2 has to be a pollutant.
I believe "CO2 Forcing" has yet proved to be true. It is still just a theory
As a consumer we will either pay for unnecessary upgrades or the cost of buying credits through higher prices.

That's my point. It will suck money out of the economy and replace it with no value. I saw an example where a farmer was paid to let his fields go fallow for a carbon credit.
