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.

California 2017 GHG inventory shows 1.2% total drop from 2016; transportation sector emissions up 1%

Green Car Congress

Transportation sector emission sources include combustion of fuels utilized in-state that are used by on-road and off-road vehicles, aviation, rail, and water-borne vehicles, as well as a few other smaller sources. The transportation sector remains the largest source of GHG emissions in the state, and saw a 1% increase in emissions in 2017.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Controlling soot from fossil fuels and solid biofuels may be a faster method of reducing Arctic ice loss and global warming than other options, including controlling CH 4 or CO 2 , although all controls are needed, according to a new study by Dr. Mark Z. These three gases are all greenhouse gases, and ozone is a surface air pollutant.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. The global economic crisis 2007/2008 only temporarily reduced emissions. WG III Summary for Policymakers. Click to enlarge.
