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.

US EPA Region 9 8-hour ozone trends, 1979-2000. These State Implementation Plans (SIPs) are the roadmaps to meeting the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) of 0.08 In 1997, EPA first established the 8-hour ozone standard, which replaced the older 1-hour ozone standard (0.12 Source: EPA.

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.

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.

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.

Research shows clean fuel-use for ships off California coast extremely effective in reducing sulfur dioxide pollution

Green Car Congress

The data were gathered during the CalNex 2010 field study organized by ARB and the National Oceanic and Atmospheric Administration (NOAA). Ships, especially ocean-going vessels, are powered by very large diesel engines that generate a tremendous amount of pollution impacting air quality onshore.

California ARB moves forward with climate and air quality actions

Green Car Congress

Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. CARB began publicly evaluating controls for SLCPs with the first AB 32 Scoping Plan in 2008 and has held at least 10 workshops and public hearings to gather input.
