Going "on location," as filming outside the studios is called, has been the thorn in many otherwise fairly sustainable film companies' sides. On location often involves trucks to transport massive amounts of equipment, huge energy costs, trying to feed lots of people in often remote places, planes and helicopters to fly crew and actors out, and so much more.

However, many of the giants in the business are making big strides towards change.

In 2007, 20th Century Fox, Universal, Paramount, Sony Pictures, Walt Disney Co, Warner and the West Coast broadcast and production arms of Disney's ABC and CBS Corp collectively diverted 20,862 tons of studio sets and other solid waste from landfills to reuse and recycling, according to trade group Motion Picture Association of America (MPAA).

As a result, the studios prevented the emission of 65,497 metric tons of greenhouse gasses -- the annual equivalent of removing 14,176 cars from the road, the MPAA said.

That's huge! But, hopefully in the future the industry will use its power to do even more.
