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.)

Exposure to ozone at levels currently deemed safe by the NAAQS clean air standards can have a significant and negative effect on lung function, according to researchers at the University of California, Davis. The previous primary and secondary standards were identical 8-hour standards, set at 0.08 Earlier post.).

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. g/hp-hr between 2007 and 2009 to a level less than or equal to 0.20 Source: CRC. Click to enlarge. For a number of the most important pollutants, levels were substantially lower than required by regulations. g/hp-hr in 2010.

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. Earlier post.) This phase was conducted at SwRI in 2012.

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. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. L) and medium-duty (6.4 L/2002 calibration and 6.4

These three gases are all greenhouse gases, and ozone is a surface air pollutant. Dessler et al., 2008] and methane [Schutz et al., Guenther et al.,
