The enleanment due to oxygen in ethanol and the low volatility of the ethanol portion of the fuel blend at low temperature gives concerns that existing and planned vehicles designed for federal and California emissions test fuels will not meet their required emissions standards when operated on mid-level ethanol blends.

However, there are some serious questions over adverse effects, particularly depletion of stratospheric ozone. Geoengineering the climate: Science, governance and uncertainty (RS Policy document 10/09, September 2009). The cost was assessed as likely to be relatively low and the timescale of action short.

The US Environmental Protection Agency (EPA) will reconsider the 2008 primary and secondary ozone standards. In 2008, EPA established a new primary 8-hour standard for ozone of 0.075 parts per million (ppm), and a new secondary standard set at a form and level identical to the new primary standard.

The largest systematic study ever conducted of human volunteers exposed to ozone air pollution has found no evidence of effects on the heart in its healthy, older participants, but did find effects on the volunteers’ ability to breathe, even at low ambient levels. Possible pathways by which ozone may cause adverse health effects.

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Major transportation related policies already in place are: The Low Carbon Fuel Standard (LCFS). Background. —Draft Scoping Plan Update.

Results from CHIE studies are used to inform the periodic review of National Ambient Air Quality Standards (NAAQS) for common pollutants, such as ozone and particulate matter (PM), and advise other policy decisions. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants.

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The last of these issues was perhaps the most vexing, prompting the U.S. Environmental Protection Agency.

A scholarly literature has documented this process in fields as diverse as engineering, risk reduction, management, and urban studies. The classic example of path dependence is the establishment of the conventional QWERTY keyboard standard on typewriters in the late 19th century and computers thereafter.
