2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. The study, the Phase 2 Report of the comprehensive Advanced Collaborative Emissions Study (ACES). These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.

Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. These narrow-focused models utilize high-resolution information about the geography, meteorology and emissions of these areas.

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Emission rates for the 1.7 A new study led by researchers at the University of Michigan compared regulated and unregulated emissions from both light-duty passenger car (1.7 L/2004 calibration engines. L/2004 calibration engines. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds.

The California Air Resources Board directed its staff to take steps to provide further locomotive and rail yard emission reductions beyond those achieved by existing US Environmental Protection Agency and state regulations and agreements. While we are pleased to have already reduced diesel emissions at the rail yards, it’s not enough.

The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate. database) from another global inventory for the year 1996.

systems in areas classified “Serious,” “Severe,” or “Extreme” for nonattainment of the ozone national ambient air quality standard (NAAQS). Vapor emissions from refueling, if allowed to escape, can contribute significantly to ground-level ozone, sometimes called smog, as well as to other types of harmful air pollution.
