Stupidly click baity title. The only corporation that does not pollute is the one that doesn't produce anything. Sure, regulations such as carbon taxes are necessary to contain negative externalities, but if there's a demand for cheap products there will be a lowest bidder that will take all market share.
Lowering our consumption is unfortunately the way to make those companies pollute less.
Also, eating industrial food over organic:
First because, per calorie produced, organic farming emits 12 to 40% more green house gases.
(Depending on the study).
Second, because you'll be less healthy and die sooner.
