> All of these things are done so that you can be provided with cheaper consumer goods

Why would you assume that irresponsible practices that are bad for the environment but save companies money always reduce the price for the consumer when they could keep raising the price of their goods to the highest price point the consumer will tolerate and simply pocket the money they save by destroying the environment.

Because most of these emissions are for producing commodities which are generally heavily competed on price.

doubtful, but even when that's true you still don't have to reduce prices by the same amount as you save harming the environment. You only have to make your prices competitive with everyone else. It's why collusion and price fixing exist.
