Study finds hybrid tugboat delivers significant reduction in criteria pollutant emissions compared to conventional version

Green Car Congress

Built by Seattle-based Foss Maritime, it began working the ports of Los Angeles and Long Beach in January 2009. criteria pollutants—nitrogen oxide, carbon monoxide, particulate matter—and the greenhouse gas carbon dioxide were measured based on the ISO 8178 protocols. Each array stores 170.1 Emissions of.

Researchers present new explanation for the long-range transport of PAH pollutants

Green Car Congress

When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).

ICCT-sponsored study of in-use testing of 3 Tier2-Bin5, CA LEV-II light-duty diesels finds wide variation of emissions against the limits

Green Car Congress

Additionally, one of the urea SCR vehicles was operated over a total distance of ~4,000 km (~2,485 miles) between Los Angeles, CA and Seattle, WA to investigate emissions reduction characteristics over extended highway driving conditions. The researchers acquired two cars from a rental agency and one from a private owner.
