California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.

Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

Panels show (a) PM 2.5 , (b) elemental carbon (EC), (c) NO x , (d) CO, (e) formaldehyde, and (f) sum of target VOCs. They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology.

CRC ACES Phase 2 report finds emissions from modern heavy-duty diesels well below required levels

Green Car Congress

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. For a number of the most important pollutants, levels were substantially lower than required by regulations. These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.

Measurements of CO2 and CO in China’s Air Indicate Sharply Improved Combustion Efficiency

Green Car Congress

The measurements provide the most detailed look at carbon emissions for a specific urbanized and industrialized region of China to date. Fuel combustion releases energy by converting carbon to CO 2 , but some is only converted to CO, losing some of the available chemical energy.
