Cameron Diaz will be traveling to tonight's 80th Annual Academy Awards ceremony in the BMW Hydrogen 7 Series.

The BMW H7 is the first hydrogen-powered luxury sedan, which emits almost nothing but water vapor, and still features all the amenities and comfort of a BMW 7 Series.

Diaz, who will present on the awards telecast, is one of many celebs going green in the BMW H7.

While the BMW Hydrogen 7 is not for sale, it is considered to be a milestone in bringing forward hydrogen as the sustainable fuel for individual transportation. Running in hydrogen mode, the BMW Hydrogen 7 essentially emits nothing but water vapor, representing a major step in reducing harmful CO2 emissions. It is not a concept car, but a production model vehicle that has successfully completed the entire Product Development Process.

A number of entertainers, politicians, business leaders and more have already opted for a BMW Hydrogen 7 as their energy-efficient ride of choice in order to evaluate the technology. Those who have recently chosen the vehicle include previously announced members of the BMW Hydrogen 7 Pioneer Program: Ed Norton, Will Ferrell, Jay Leno, opera star Placido Domingo and famed director Steve Gaghan, among others. Other notable figures who have opted for rides in a BMW Hydrogen 7 include Brad Pitt and Angelina Jolie at the "Ocean's 13" premiere in Hollywood; Fox Entertainment Chairman Peter Liguori at the FOX All-Star Party in Santa Monica; Richard Gere and Sharon Stone at the Cinema for Peace Gala in Berlin.
