Generally BS - there always is economic justification in not cooking consumers that drive the economy. The same as there is economic sense in having seven children - in many parts of China, children are a form of retirement pension, well worth the fifteen years investment in food, as they will be repaying you back for the next thirty.
Short term investments in greener production can result in long term profits by not killing the planet, flooding Sahara, blowing up the sun or whatever the Greens have to say today.
Not to mention the consumerist value of the greenhouse effect - buy new, buy green! Buy a Mac that produces 15% less greenhouse gases and save the planet.
Well, that is, if the greenhouse effect is true.
