Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

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.

CRC ACES Phase 2 report finds emissions from modern heavy-duty diesels well below required levels

Green Car Congress

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.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

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.

Large scale epidemiological study associates PM2.5, NO2 pollution with kidney, bladder and colorectal cancer death

Green Car Congress

The open-access study, published in Environmental Health Perspectives , included more than 600,000 adults in the US who participated in the Cancer Prevention Study II and who were followed for 22 years (from 1982 to 2004). More than 43,000 non-lung cancer deaths were registered among the participants.

California ARB Seeks Further Reductions of Diesel Emissions at State Rail Yards

Green Car Congress

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.

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

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.
