NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. They show how nitrogen dioxide concentrations during spring and summer months, averaged from 2005-2007, compare to the average from 2009-2011.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.

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.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

The global economic crisis 2007/2008 only temporarily reduced emissions. Commercially available liquid and gaseous biofuels already provide co?benefits giga tonne carbon dioxide equivalent (GtCO 2 eq) (2.2%) per year from 2000 to 2010 compared to 0.4 GtCO 2 eq (1.3%) per year from 1970 to 2000.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

In 2005, Congress enacted the Renewable Fuel Standard as part of the Energy Policy Act (EPAct) and amended it in the 2007 Energy Independence and Security Act (EISA). Currently, no commercially viable biorefineries exist for converting cellulosic biomass to fuel. Barriers and opportunities.
