Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

However, the use of CFT resulted in a remarkable reduction in carbonyl emissions in comparison with using DF. lower ozone formation potential of the carbonyl compounds present than DF under the identical operating conditions. There was no significant difference in the profiles of total carbonyl emissions between CFT and DF. CFT had 16.5–44.1%

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.

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

In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. —Stratton et al. Many other factors have less quantifiable impacts.

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.,

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.
