The young Oscar nominee Keisha Castle-Hughes says she'll pass on taking a stretch limousine to her first Academy Awards.

The 13-year-old Whale Rider star and best actress contender is one of a handful of celebrities who will be chauffeured to the gala in a Toyota Prius to help promote the use of hybrid cars powered by both gasoline and electricity.

"Even though I am not old enough to drive, I am old enough to know that the environment is in danger," Castle-Hughes said in a statement. "By taking a hybrid car to the Oscars, I can show my support for helping the environment."

Charlize Theron, Sting, Robin Williams, Jack Black, Tim Robbins and Will Ferrell were among those committed to arriving at the red carpet in a hybrid car, courtesy of the environmental group Global Green USA.

"In addition to being obviously economical and environmentally friendly, they drive great and are just plain sexy," said Ferrell, who owns a Prius.

Alternative fuel vehicles are "the right thing to do to reduce air and greenhouse gas emissions," said Matt Petersen of Global Green USA, an affiliate of Green Cross International.
