The Producers Guild of America is launching an expanded version of its Green Production Guide, an interactive website that provides tools to help operate productions that are more sustainable.The PGA guide, which debuted in August, 2010, will now offer additional resources to help producers run environmentally friendly productions. It gives access to a global database of over 1,500 vendors offering sustainable or environmentally sensitive services and products. New or improved features include a refined search tool to find online green vendors; a graphically enhanced carbon calculator to quantify a production’s carbon emissions; and a new guide detailing best practices for sustainable production. Several studios, including Disney, Fox, NBC Universal, Sony Pictures and Warner Bros. – all of which helped fund the initiative – use the carbon calculator on at least a portion of their productions. Film commissions linking to the Green Production Guide on their sites include those in California, Louisiana, New York, New Jersey, Alabama, Florida, Indiana, New Hampshire, Oregon, Oklahoma, Ohio, New Mexico, Pennsylvania, North Carolina, Arizona, Maryland, Colorado, Maine, South Carolina, Nevada, Kansas, Missouri, Montana, and Georgia.
