The California Air Resources Board unanimously adopted unenforceable greenhouse gas reduction goals by targeting sprawling developments in regions across the state. \u201cThis is not a mandate and there is no punishment if the target is not met,\u201d Mary Nichols, Air Board chair, said September 23. However, she insisted her agency was \u201con the side of history.\u201d The board vote helps put skin on the bones of SB 375. The legislation by Senator Darrell Steinberg (D-Sacramento) enacted in 2008 attempts to move the state away from sprawling land developments\u2014with their ensuing use of vehicles to span distances. The transportation is sector is the largest source of greenhouse gas emission in California, followed by the electricity sector. The resolution aims to support and encourage 18 planning regions in the state to build compact sustainable developments to reduce vehicles miles traveled to cut carbon emissions and other air pollutants by up to 15 percent by 2035. Specific targets for the state\u2019s largest metropolitan regions\u2014Southern California, San Diego, San Francisco Bay Area, and Sacramento\u2014are between 7-8 percent reductions by 2020 and 13-15 percent by 2035. The San Joaquin Valley goal is set at 5 percent by 2020 and 10 percent emission cuts by 2035. \u201cBy standing up to special interests that benefit from \u2018business as usual\u2019 sprawl, SB 375 is an incredible opportunity to reverse skyrocketing trends in chronic illnesses and obesity, reduce the impacts of climate change and tackle a root cause of California\u2019s worst-in-the-nation air pollution,\u201d stated American Lung Association in California chief executive officer Jane Warner. Opponents claim the resolution would stifle economic growth. The current economic downturn is constricting driving. Vehicle miles traveled per capital is predicted to decrease 2 percent the next decade because of the economic downturn, accord to Air Board staff. \t The board is set to review its targets and how well regions are meeting them every four to five years.
