Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. The publication gives the opportunity for an “apples-to-apples” comparison between the environmental impacts of the two types of powertrains: same manufacturer, same model, same boundary conditions.

NOAA greenhouse gas index continues climbing; 1.29 in 2010

Green Car Congress

the combined heating effect of long-lived greenhouse gases added to the atmosphere by human activities has increased by 29% since 1990, the index year used as a baseline for comparison. It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases. in 2010—i.e.,

MIT study finds including non-CO2 emissions from synthetic aviation fuel in lifecycle analysis of climate impact can lead to decrease in relative environmental merit; need for a holistic analysis framework

Green Car Congress

Life cycle analyses of biobased, ground transportation fuels assume that the emissions from fuel combustion are equal and opposite to the emissions absorbed from the atmosphere during growth of the feedstock. In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming.

Emissions of Air Pollutants down in EU-27

Green Car Congress

The downward emission trend of three main pollutants which cause ground-level ozone continued in 2007: carbon monoxide (CO) fell by 57%, non-methane volatile organic compounds (NMVOCs) were down by 47% and nitrogen oxides (NO x ) have dropped 36%. EU-27 emissions of all four pollutants were lower in 2007 than in 2006.

That being said, even a car that derives its energy from coal power plants would be far more clean. Having centralized energy production in that way allows for centralized pollution control measures, filters, so-called "clean coal" rather than depending on X number of cars, manufacturers, and consumers to deal with pollution control.
