Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. The annual averages of ozone levels in study areas were between about 10 and 25 ppb.

Changes in emissions by Scoping Plan sector between 2000 and 2017. Emissions from transportation sources were relatively constant from 2002 through 2007, declined through 2013, then increased by 9.0 Compared to 2016, California’s GDP grew 3.6% while the carbon intensity of its economy declined by 4.5%.

In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships.

per year from 2000-2007. For 30 reference glaciers in nine mountain ranges tracked by the World Glacier Monitoring Service, the mean rate of loss since 2000 has roughly doubled since the rate during the previous two decades. In 2008, the minimum ice extent was 9% greater than in 2007, but still the second lowest on record.

Total anthropogenic GHG emissions were the highest in human history from 2000 to 2010 and reached 49 (±4.5) The global economic crisis 2007/2008 only temporarily reduced emissions.

Stanford Professor Urges EPA to Include Black Carbon in Endangerment Finding

Green Car Congress

Jacobson first showed in 2000 that black carbon was the second-leading cause of global warming after carbon dioxide in terms of radiative forcing and, in 2002, that its control was the most effective method of slowing warming. C increased Arctic warming from 1890 to 2007. F, with about 40% due to ozone. Earlier post.).

California ARB Seeks Further Reductions of Diesel Emissions at State Rail Yards

Green Car Congress

In 2000, the ARB established California’s Diesel Risk Reduction Plan, which aims to reduce diesel emissions to 85% below 2000 levels by 2020. NO x helps create ground-level ozone, or smog. BNSF has been operating four liquefied natural gas yard locomotives in downtown Los Angeles since the mid-1990s.
