US research: clean trucks are less clean than you might think

A new ICTT report assesses the real-world nitrogen oxide (NOx) emissions behavior of heavy-duty diesel vehicles in the United States measured using portable emissions measurement systems (PEMS). This assessment is based on 160 PEMS tests from engines certified to 0.2 grams per brake horsepower-hour (g/bhp-hr) of NOx.

The Lancet: new evidence on asthma incidence attributable to NOx

Paediatric asthma incidence is associated with exposure to traffic-related air pollution (TRAP), but the TRAP-attributable burden remains poorly quantified. Nitrogen dioxide (NO2) is a major component and common proxy of TRAP. In a new study, researchers estimated the annual global number of new asthma cases attributable to NO2 exposure at a resolution sufficient to resolve …
