Environmental consequences affect profits. A "environmental consequence" can cause a CEO to be fired.
Hybrid cars aren't making a profit and will unlikely never be very profitable, yet they are made- for "environmental reasons". And the shareholders aren't firing these CEO because of this [at least not until it's realize that hybrids aren't as environmental friendly as is currently imagined].

It's all too common for a company to operate at a loss.
If more CEOs followed "Profit over all else" the world would be a better place, but it's sort of like saying politicans always spend less than the revenue recieved from taxes.

"Environmental consequences" are the main reason the US imports so much oil. "Environmental consequences" are the main reason only about 20% electrical power in the US is produced by nuclear energy. But I don't mean real environmental consequences; I mean whatever happens to be the public hysteria of the moment.
