Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation. Jakober, 2008). There was no significant difference in the profiles of total carbonyl emissions between CFT and DF. reduction in total carbonyls and a 6.0–100%

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

California ARB Expands Assistance Program for Truckers to Reduce Diesel Emissions

Green Car Congress

The changes made to the statewide Voucher Incentive Program, also known as the VIP, will make funding available to a larger variety of trucks that will help owners comply early with the statewide truck and bus regulation passed in 2008. VIP is part of the state’s overall plan to cut toxic diesel emissions 85 percent by 2020.

NOAA, partners find about 98% decline in VOCs concentrations in LA Basin over last 50 years despite 3x increase in use of gasoline and diesel

Green Car Congress

In California’s Los Angeles Basin, levels of volatile organic compounds (VOCs) pollutants have decreased by about 98% since the 1960s, even as area residents now burn approximately three times as much gasoline and diesel fuel. This indicates that the main VOC source in the LA basin is likely gasoline vehicle emission.

CARB approves $423M plan to mitigate harm from Volkswagen defeat devices; significant investments in heavy-duty vehicles and equipment sectors

Green Car Congress

The California Air Resources Board (CARB) approved a plan to mitigate statewide harm from more than 10,000 tons of smog-causing pollutants released in the state due to Volkswagen’s (VW) use of illegal “defeat devices” in diesel passenger cars. The National VW Environmental Trust provides California with $423 million for this purpose.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. Earlier post.) Earlier post.)
