Sorry, do companies actually make money polluting, as in that is their business strategy?
Because otherwise, not polluting isn't going to increase the cost of living or cause cripling distress on the poor.
Reducing pollution is expensive. If it was free, companies would already do it. The only reason to pollute v/s not pollute is because the former helps profits.
So if it costs more money for, let's say... food manufacturers to produce their goods, the cost of those goods will necessarily have to increase. And the people who need food will suffer because they'll have to dedicate more of their scarce resources to that acquisition. This disproportionately impacts the poor and lower class. Their lives become significantly more difficult.
Now expand that effect across all industries - energy, transportation, manufacturing - and the costs will be pervasive and damaging. We're not talking about $1 more for a loaf of bread - we're talking about everything.
Of course you're a well-off IT guy just like the rest of us, so you won't feel it. Who cares if the kids in the bad neighborhoods go to bed hungry, right? Praise Gaia!
