It's not like people don't know, it's more like there's not much we can do about it (other than voting).
It's up to governments to come up with and enforce laws that prevent corporations from releasing millions of metric tons of greenhouse gasses. Without strict laws in place, there's too little incentive from being moral or being long-term oriented, also your competition who don't will run you out of business with the extra profits.
There's also very few consumers willing to investigate/research the pollution generated from all companies related to making/delivering the products they buy. So being "greener" isn't really much of an advantage.
