Hollywood's major television and film studios on Friday unveiled a guidebook with rules they plan to follow to try to reduce their carbon footprint and workplace waste.
In late 2006, university research here charged that the film industry was a major source of the sprawling megalopolis' notorious pollution, topped only by oil refineries.
So this "Best Practices Guide for Green Production" announced by the Motion Picture Association of America (MPAA) is aimed at improving the industry's record and reputation.
"A new norm is emerging in which eco-friendly practices are best business practices, and ... behind the scenes, every major studio is getting in on the act," said MPAA chief Dan Glickman.
The guide offers ideas for environmentally responsible approaches to issues as diverse as filming on sets, transport, post-production work and even hair and makeup.
"Hollywood's film studios have come a long way since they started recycling in the 1970s," said Gary Petersen, environmental member of the California Integrated Waste Management Board.
"Studios' waste reduction and recycling efforts are having a real impact on reducing greenhouse gasses and they have implemented many other responsible practices that showcase how the private business sector can contribute to sustainability," he added.
