Ok I'll reword. I support creating economic incentives to promote cleaner technology. Picture this. 2 cement plants. One uses natural gas to fire the cement, it costs them $2/ton and emits 0.15 tons CO2. the other uses old tires for heat, it costs them $1.80/ton and emits 0.5 tons CO2. a tax of 0.50c per ton of emissions raises the cost of the clean tech by like 5 cents, and the shitty one by almost 25 cents, so now theyre cost competitive, meanwhile the average cost is negligibly much higher to pass on to the consumer, and you've effectively phased out the dirtier process. And I think there are actually a lot of companies operating on the dirtier plan knowing that they'd get undercut by someone going the crappy route if they went with the better cleaner tech. It would make things easier to run on natural gas, morally more sound, better public reception, but without the ncentive they cant sell stuff competitively cheaply.
