The Health Effects Institute (HEI) has launched two new studies funded under RFA 21-1, Quantifying Real-World Impacts of Non-Tailpipe Particulate Matter Emissions. The new studies are: Improved Characterization of the Real-World Contributions and Impacts of Non-tailpipe Particulate Matter Emissions ,” led by Greg Evans, University of Toronto.

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.

The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment. NO x is a precursor for both ground level ozone and secondary PM 2.5 NO x is a precursor for both ground level ozone and secondary PM 2.5

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 CH 4 emissions represented 8.8%

Improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO 2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions. —Susan Anenberg.
