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.

GWP100 weighted specific climate impact (g CO 2 -eq per pkm) as a function of vehicle occupancy. A team from Austria and Norway has found that the climate impact from a long-distance trip (500–1,000 km, or 310–621 miles) can easily vary by a factor of 10 per passenger depending on mode choice, vehicle efficiency, and occupancy.

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.

Cars and trucks account for over half of the emissions that contribute to ozone and particulate matter as well as about 30% of the total greenhouse gas emissions in California. Exhaust from cars and trucks have been known to exacerbate a variety of conditions such as lung and heart disease, and asthma, and even contribute to premature death.
