Report: Reducing Emissions * USA
* California - Diesel truck emissions in Oakland fall sharply
Oakland,CAL,USA -Berkeley Transportation Letter, by Christine Cosgrove -17 Jan 2012: -- West Oakland’s 22,000 residents live beside three freeways, two rail yards, and the nation’s fifth busiest container port—a destination for thousands of diesel trucks hauling goods back and forth daily while spewing pollutants into the neighborhood around them... According to a 2008 health risk assessment by the California Air Resources Board, diesel particulate matter (PM) emissions from Oakland’s port operations, the rail yard, and the freeways result in 1,200 excess cancers per million for residents of West Oakland. The report further states that diesel PM is responsible for higher premature deaths and hospital admissions for respiratory and cardiovascular disease, as well as asthma-related and lower respiratory symptoms. Diesel trucks are by far the greatest contributor to these emissions, compared to trains, cargo handling equipment, and ocean going vessels... So imagine reducing emissions of unhealthy pollutants from these trucks by half—in a matter of months... Civil and Environmental Engineering Professor Robert Harley says recent field studies his research team has undertaken show that’s just what has happened as a result of state regulations that banned the oldest, dirtiest trucks and set deadlines for retrofitting middle-aged trucks with diesel particle filters... The results have been heartening, and in at least one way, unanticipated...
