In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 Tg or million metric tons CO 2 equivalent.)

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. This is, however, the lowest growth rate over the past 4 years. The inner ring shows the broad Scoping Plan sectors. Source: ARB.

Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant. Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface.

Losses of tropical and temperate mountain glaciers affecting perhaps 20-25% of the human population in terms of drinking water, irrigation and hydro-power. per year from 2000-2007. In 2008, the minimum ice extent was 9% greater than in 2007, but still the second lowest on record. Global emissions were growing by 1.1%

After a thorough scientific review ordered in 2007 by the US Supreme Court, the US Environmental Protection Agency (EPA) issued a proposal with two distinct findings regarding greenhouse gases. Climate change has the potential to produce increases in ground-level ozone in many regions, according to the report.

Warming of the air by any chemical, including soot, enhances natural surface emissions of water vapor [e.g., 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b]. These three gases are all greenhouse gases, and ozone is a surface air pollutant. Dessler et al.,

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. There is an obvious link between environmental impacts estimated by life-cycle impact assessments and water quality problems described at the regional scale. Source: “Assessing Biofuels”.
