TMZ is citing Page Six as reporting that "Before Sunrise" beauty Julie Delpy took a page from Al Gore’s environmentally conscious book while in Chicago.

The French actress was in town promoting her new film "Two Days in Paris" when she saw a truck idling in front of the restaurant she was in."

An ardent environmentalist, Delpy was vexed by truck, and jumped in the cab to turn it off, only to find out that the truck had to be left idling because it contained fresh meat and poultry.
