> environmental impact Many (but certainly not all) externalities are process waste and an often an opportunity for margins improvement if you can figure out how to eliminate that waste. Now, if you can take those externalities that are not process waste but are still bad for the environment and you can put a price on them that needs to be paid, competition is going to drive businesses to figure out how to reduce the externalities. This is the premise behind buying carbon credits/offsets. The problem is that we don't yet have good ways to price in all externalities into the final cost of goods sold. That should be the problem we tackle.
