Can you point to the data that suggests these evil corporations are ruining the planet? Carbon emissions are down in every western country since 1990s. Not down per-capita, but down in absolute terms. And this holds even when adjusting for trade (i.e. we're not shipping our dirty work to foreign countries and trading with them). And this isn't because of some regulation or benevolence. It's a market system that says you should try to produce things at the lowest cost and carbon usage is usually associated with a cost. Get rid of costs, get rid of carbon.
Other measures for Western countries suggests the water is safer and overall environmental deaths have decreased considerably.
The rise in carbon emissions is due to Chine and India. Are you talking about evil Chinese and Indians corporations?
