The Port of Long Beach has cut diesel particulates by 81% since 2005, according to its 2012 Emissions Inventory. The results for 2012 mark six straight years of improving air quality in the harbor area due to the Port’s focused efforts to reduce air pollution caused by goods movement. Greenhouse gases were lowered by 24%.
These plans will reduce pollution to the level required by the health-based 1997 PM 2.5 EPA is, however, proposing to disapprove the plans’ contingency measures because they do not provide sufficient emissions reductions. In large part, the solution will be found in moving quickly towards zero emission transportation systems.
Meeting standards for fine particle pollution, or PM 2.5 , is the San Joaquin Valley’s most critical air quality challenge.

Projects funded under this Program must achieve early or extra emission reductions not otherwise required by law or regulation.
Recent reports from China ( earlier post ) cited local environmental officials suggesting that battery maker Johnson Controls was the source of lead in a pollution incident in Shanghai affecting some 21 children. Johnson Controls has now issued a statement saying that it has “ no reason to believe we are the source of the issue.”
However, the fuel-cycle PM 10 , PM 2.5 , SO 2 , and NO x emissions of EVs could be up to five times higher than those of ICEVs (internal combustion engine vehicles) and CNGVs. emissions are less important because of the low contribution of light duty vehicles to national PM 10 and PM 2.5 While the increases in PM 10 and PM 2.5

Work is already underway to update a 2006 review of the science that will result in the reconsideration of the ozone standard in 2013.
Consequently, vehicle emissions have become an increasingly conspicuous contributor to air pollution in Chinese urban areas. Fourteen percent buses used gasoline, were equipped with carburetors, and had no any end-of-pipe emission control devices. Light-duty gasoline vehicles were the major contributors to CO and VOC emissions.
