Saudi Arabia is trying to enlist other oil-producing countries to support a provocative idea: if wealthy countries reduce their oil consumption to combat global warming, they should pay compensation to oil producers.

The kingdom is once again gearing up to take a hard line on the issue at international negotiations scheduled for Copenhagen in December.
