And I am not talking about outdated films for camera exposure. I am talking about movies that are no longer just critical and entertaining, I am talking about movies that soon will be carbon neutral. What this means is that all carbon dioxide emitted during the filmmaking process, lights, cameras, transportation, and other activities, was summed up and offset by investments in renewable energy projects.

What are these films? The list is getting longer but the ones that are known are Sweet Land, An Inconvenient Truth, The Day After Tomorrow and Syriana. The bonus is they are good films and that they have a clear message about the environmental or the energy situation.

So next time you watch a carbon neutral movie, make sure your pop corn is carbon neutral as well. Read more about this story here.
