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. Together, PM 2.5

Study finds propane school buses significantly decrease NOx emissions compared to diesel

Green Car Congress

According to a study commissioned by the Washington, DC-based Propane Education & Research Council (PERC), NO x emissions measured from propane autogas school buses were substantially lower than those measured from diesel school buses. For the stop-and-go route, NO x emissions were 34 times higher for the diesel school bus.

Study: curbing diesel emissions could reduce mortality rates in big cities

Green Car Congress

Freight transportation is a pillar of the US national economy, but while long-haul trucks account for less than 6% of the vehicle miles traveled over US highways, they account for about 40% of the emissions of air polluting particulate matter and about 55% of nitrogen oxides, the precursor to ozone in the atmosphere, the study said.
