Yeah, sounds like a cheap excuse they are looking for.

On the Paris OPEC meeting (2005?) some oil minister from Arabia spoke about doubts in regard of future oil demand.

I was really astonished about that - if there is one sure thing it is the quenchless western thirst for oil, or am I wrong? That's definetely something they can count on for decades.

From Biopact:

"In two different interviews ahead of the G8 summit, OPEC secretary-general Abdalla El-Badri contradicts himself: in the first, he says biofuels threaten oil investments and may cause petroleum prices to go "through the roof", whereas in the other, he says the cartel does not feel threatened by climate change measures aimed at reducing carbon dioxide emissions, of which biofuels are an important part"

Round and round we go.
