"What we strive to do with GreenTRIP is create something that is very easily implementable so that it can be done early in the development process," said Jeffrey Tumlin, Principal of Nelson Nygaard Consulting Associates and a member of GreenTRIP's advisory board. "We want to focus on the key things that developers and municipalities can do to have a positive impact on greenhouse gases."
Tumlin added, "GreenTRIP tries to change the regulatory process."
Developed explicitly to complement areas where the LEED Neighorhood Development (LEED ND) green building certification falls short of being prescriptive, GreenTRIP rewards projects that reduce traffic and make a strong connection between sustainable development and pollution from the transportation sector, which accounts for more than 40 percent of California's GHG emissions. Funding for the new certification comes from grants from the Bay Area Air Quality Management District, the Rockefeller Foundation, and the Silicon Valley Community Foundation.
Using the URBEMIS emissions model developed by the California Air Resources Board, GreenTRIP gives developers credits for reducing overall driving relative to the average regional VMT. GreenTRIP attempts to impact developments at the beginning phases of design, encouraging developers to situate near transit and take steps to reduce driving [PDF].
