Prices fluctuate all the time. How many tons of CO2 are consumed by the machine that spins yarn? Sure there’s an added cost, but of pennies — this strikes me as a weak counter argument. At a nominal price of $20/ton, a few things will go way up in price, but almost everything else will see at best a blip, with an added incentive to the producers to reduce the carbon content because that matters at industrial scale (company saves $3m over 30m units by switching to a non-petroleum glue whatever) not to an individual consumer (who would see a cost increase of 10¢).
