Deal on greenhouse emissions

Looks like California is about to pass the nation's toughest state initiative to control greenhouse emissions. Gov. Arnold Schwarzenegger and the Democrat-controlled legislature have reached a compromise on the bill. It's expected to pass both the Assembly and Senate before the session ends tomorrow night. "I am happy to announce we have reached a historic agreement on legislation to combat global warming," Schwarzenegger said Wednesday. The measure apprently will include provisions to trade emission allowances in a market. That had been a stumbling block earlier in the week.
