Researchers suggest that air quality tests need simplifying to help reduce dangerous emissions

Green Car Congress

New methods of testing and simulating air quality should be considered in order to help policy makers have a more accurate understanding of how emissions affect air pollution levels, new research suggests. The researchers compared current techniques used to describe atmospheric chemical reactions against more historical techniques.

ITF: measures to decrease road freight CO2 emissions

Green Car Congress

A new brief published by the International Transport Forum (ITF)—an intergovernmental organization at the OECD with 59 member countries— identifies proven measures that decrease road freight’s CO 2 emissions. This will offset any expected efficiency gains and lead to an increase in emissions by 2050, not a reduction.

Ricardo Study Suggests E15 Poses Minimal Risk to MY 1994-2000 Vehicles

Green Car Congress

A study by Ricardo for the Renewable Fuels Association (RFA) concludes that the adoption of E15 as the blend limit for standard US pump grades of gasoline rather than the current E10 should not adversely affect vehicles manufactured between 1994 and 2000 in terms of their performance and durability based on normal specifications and usage profile.

Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

A study by researchers from the University of Denver and the University of Puget Sound indicates that high-mileage light-duty fleets contribute higher emissions and emissions share than expected based on their actual numbers in the fleet. Most emission inventory calculations use a computer model to estimate the fleet’s emissions.

PBL/JRC: Global CO2 emissions increase to new all-time record in 2013, but growth is slowing down

Green Car Congress

Global CO 2 emissions from fossil fuel use and cement production reached a new all-time high in 2013, according to the annual report “Trends in global CO2 emissions”, released by PBL Netherlands Environmental Assessment Agency and the European Joint Research Centre (JRC). In 2013, global CO 2 emissions grew to the new record of 35.3

U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

A study of emissions from gasoline direct injection (GDI) vehicles in an urban near-road environment in Toronto over a wide range of weather conditions (February 2014 to January 2015) found that—other than for NO x and CO—the GDI engines had elevated emissions compared to the Toronto fleet. m from the roadway. 5b04444.
