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.
Air pollution is considered a large threat to human health. Freight transport vehicles are responsible for a large share of air pollution. The impact of pollutants is heavily depending on the number of people present in the proximity of the emission source. This impact is generally calculated using the impact-pathway-approach.
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 …
In a new paper, Cedric D. Koolen and Prof. Dr. Gadi Rothenberg outline the serious problems caused by air pollution in Europe. Using two types of metrics, level assessment, and trend assessment, they quantify the contribution of ammonia, NOx, SOx, non‐methane volatile organic compounds, and particulate matter in terms of years of life lost per capita …
Cities using, or planning to use, the Euro 6 standard as the basis for their low-emission zones (LEZs) will not deliver the air quality improvements they expect, AIR (Allow Independent Road-Testing) has warned. Euro 6 (or Euro VI for trucks) is the European benchmark standard for vehicle emissions, while vehicles that meet the standard receive …
Paris and London are Europe’s two megacities. Both experience poor air quality with systemic breaches of the NO2limit value. Policy initiatives have been taken to address this; some European-wide (e.g. Euro emission standards) and others local (e.g. Low Emission Zones). A study by Font et. al. evaluated trends in NOX, NO2 and particulate matter (PM10, …
Truck drivers have the highest overall exposure to air pollution and yet are being overlooked in the air quality debate, according to scientists at King’s College London. Research by UK environmental charity Hubbub in cooperation with the King’s College and The Times examined how poor air quality affected people living and working in London.
Amsterdam will stop its pilot with 8 City Trees to improve air quality. It was stated that in the current set of City Trees will not have a significant impact (defined as a 10-20% decrease) of the concentrations of particulate matter and nitrogen dioxide on the facades of houses in the Amsterdam Valkenburgerstraat.
Exhaust from vehicles is a major source of air pollution worldwide. A by the ICCT study links state-of-the-art vehicle emissions, air pollution, and epidemiological models to estimate the impacts of transportation sector emissions on ambient PM and ozone and associated health impacts in 2010 and 2015.
Exposure to environmental pollution is thought to cause as many as 9 million premature deaths each year. The largest health impacts are associated with air pollutants and particulate matter in particular. The latter is thought to cause an average reduction in life expectancy of 6 to 12 months in Europe.
