The Southern California Association of Governments adopted a $524.7 billion land use and transportation plan April 4 designed to reduce by 9 percent per capita vehicle-related greenhouse gas emissions in a six-county area by 2020, and 16 percent by 2035, relative to 2005 levels. Approved in a unanimous vote, the 25 year plan hopes to increase mobility in one of the most congested parts of the country by making significant investments in transit, pedestrian and bike paths, multifamily housing, and rail systems and roads.
