Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

California ARB approves air quality plan for South Coast Air Basin ahead of 2023 deadline; calls for Federal action

Green Car Congress

The California Air Resources Board (CARB) voted to approve an updated plan for the South Coast Air Basin aimed at further cutting smog-forming emissions to attain the federal 8-hour ozone standard. The remaining reductions are reasonably available from further action at the federal level, CARB said. —CARB Chair Mary D.

Berkeley study identifies diesel as main source of vehicular secondary organic aerosols

Green Car Congress

The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone. However, concerns about engine performance and the cost of fuel production led the state to allow higher aromatic levels in diesel fuel.
