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. Ground-level ozone is mostly produced when ultraviolet light reacts with pollutants from fossil fuels.

Study finds shipping emissions in East Asia contribute to up to 37.5K premature deaths each year

Green Car Congress

A study by a team of researchers from China and the US has shown that shipping emissions in East Asia accounted for 16% of global shipping CO 2 in 2013, compared to only 4–7% in 2002–2005. However, the climate and air quality impacts from shipping are not well understood in this region.

EPA proposes approval of new ozone plans for the two of the worst Air Quality Zones in US: California’s San Joaquin Valley and South Coast

Green Car Congress

The two areas suffer from some of the worst air quality in the country due to a number of factors, such as meteorology, geography, climate and weather. These new SIPs demonstrate that, by 2024, pollution will be reduced to the level needed to attain the 1997 8-hour ozone standard of 0.08 Earlier post.). For the SJV to attain 0.08

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. Immediate GHG control is still absolutely necessary to stem short and long-term climate damage. Mark Jacobson.
