The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al.

Imaging study: air pollution impairs function of blood vessels in lungs

Green Car Congress

Between 2009 and 2013, transthoracic echocardiography including an evaluation of pulmonary pressure was conducted in 16,295 individuals and correlated with average air pollution in Brussels on the same day and in the last five and ten days. The volunteers were exposed to ambient air or dilute diesel exhaust with a PM 2.5

Ford researchers report detailed study of the effect of different ethanol blend levels on emissions from FFVs

Green Car Congress

The chemistry of a fuel impacts the emissions from an engine, with the most obvious example being unburned or partially burned fuel which is a major component of engine exhaust. Engine-out exhaust contains typically 1?3% via the unburned or partially burned fuel which is a major component of engine exhaust. —Hubbard et al.

PNNL team finds correlation between reaction mechanism for zeolite SCR catalyst for NOx aftertreatment and bacterial enzyme catalysis

Green Car Congress

Recently, researchers have produced a new zeolite that is surprisingly stable and makes very little nitrous oxide from nitric oxide, a chemical that depletes ozone. Peden, and János Szanyi (2013).

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

The study found the potential for 1,500–2,000 Bering Strait transits in 2025, a three- to four-fold increase from 440 transits in 2013 (based on the medium-growth scenario). MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances. Earlier post.).

California ARB Seeks Further Reductions of Diesel Emissions at State Rail Yards

Green Car Congress

The top set of recommendations call for: Replacing existing switch and medium horsepower locomotives with cleaner locomotives (2010-2013); Retrofitting switch and medium horsepower locomotive with particulate matter and oxides of nitrogen (NO x ) after-treatment devices (2012-2016); and. NO x helps create ground-level ozone, or smog.
