Olivia Wilde: Environmental Media Awards 2009

Olivia Wilde celebrates the 20th Anniversary of the Environmental Media Awards held on the backlot at Paramount Studios on Sunday (October 25) in Los Angeles, Calif.

The 25-year-old House actress, who wore a Stella McCartney gown to the event, said Hollywood sets tend to be “very wasteful places,” but things are changing.

“We can try to waste less paper and have scripts distributed more responsibly. We can use corn-based products for craft services and we can go as far as solar-powered trailers,” Olivia told the AP. “It’s not overwhelming if you take it step by step.”

Olivia was recently crowned “Hottest Woman Alive” by Maxim magazine.
