Leonardo DiCaprio is trying to save the world. This time, it’s not in a fictional action movie, but a nonfictional documentary. Titled “Carbon”, the short documentary was released Wednesday over YouTube. DiCaprio narrated the film, which demands action to minimize climate change and “put a price on Carbon.”

“If national governments won’t take action, your community can,” the actor says in the narration. “We can move our economy town by town, state by state to renewable energy and a sustainable future.”

“Carbon” is but the first in a four part series called Green World Rising made by the production company, Tree Media. According to their website, the next episode concerns renewable energy, the third deals with mitigating climate change with the help of natural ecosystems, and the fourth deals with the potential danger of methane release from a melting arctic.

Green World Rising is supported by the Leonardo DiCaprio Foundation. The series is directed by Leila Conners, who, according to her IMDB page, has directed other environmental documentaries such as The 11th Hour, We the People 2.0, and Into Eden. She is also the founder of the Tree Media group in which, according to its website, she “set out to build a production company that creates media to support and sustain civil society by telling inspiring stories.”

DiCaprio has been a long time champion of environmental issues. A few months ago, NBC reported that his foundation would pledge seven million dollars to help preserve the world’s oceans.

One.org made a list of “21 Things Only Activists Will Understand”. Clocking in at number 18 is “when Leonardo DiCaprio finally makes a film about your issue”. Environmental activists should be quite pleased DiCaprio is not only making one film about this issue, but four.
