While ABC’S hit series “CASTLE” is one of my favorite television series for its clever murder mysteries and hysterical writing — its stars are also quickly earning some green cred in my book for their recent headlines.

Back in August, Nathan Fillion and co-star Jon Huertas put electric carmaker start-up Arcimoto on the map after an enthusiastic test drive of their Pulse three-wheeled electric car. Fillion, who stars as Richard Castle on the show, said that him and Huerta were looking for a green way to get to the studio set each morning. After he stumbled upon the Pulse, he was sold. “I found it! I found my spaceship! It’s real and I’m getting it!,” he tweeted to his more than 650,000 Twitter followers.

Fast forward a couple months, and the other two main leads on the show, Stana Katic and Seamus Dever, have hooked up with the Sierra Club to document their experiences going carless for seven days over the course of a month in Los Angeles. Produced by Katic, who plays Detective Kate Beckett on the show, the “Alternative Travel Project” features a series of videos showing the stars getting around LA via bike, bus, and subway.

“When you’re not caught in the bubble of your car, the city blooms,” Katic told the NY Times.

In partnership with the project, the Sierra Club is also sponsoring a no-car pledge effort. “Help reduce our dependence on oil,” the site reads. “Join Stana, Seamus, and the Sierra Club — pledge to give up your car for a day and join the movement of people around the country who are trying a car-free experiment!”

Check out the first two videos in the series after the jump below.

    Everytime I read this and similar stories, it makes me laugh. Poor people have been doing this for years.Even though they crave cars because public transportation is very unreliable, especially when you rely it for important stuff: ex: doctor’s appointments, work etc.. The only difference is that bicycles have rivaled second to public transporation in options to get to and from places. Both of these items have one thing in common. The predominately white enviromental and bicycle movements ignore us. We are not good enough to promote alternative transporation options.
