MIT study finds real-world NOx from diesels cars in Europe greatly exceeds laboratory levels; transboundary emissions cause 70% of health impacts

Green Car Congress

A new study by MIT researchers, published this month in Atmospheric Environment , finds that in Europe, 10 major auto manufacturers produced diesel cars, sold between 2000 and 2015, that generate up to 16 times more NO x emissions on the road than in regulatory tests—a level that exceeds European limits but does not violate any EU laws.

Air pollution regulations over last decade in Chinese city has halved health costs

Green Car Congress

Results appear in an open access paper in the journal Environment International. Between 2000 and 2012, these included mandating the closure of many polluting sources, auditing companies that produced large amounts of toxic and hazardous materials, setting pollutant emissions standards, and promoting energy efficiency and pollution reduction.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

They also found that abundant natural gas can, however, help reduce the costs of achieving GHG reduction goals. Shale gas in particular has grown rapidly, from less than one percent of US production in 2000 to 34% in 2012, and projections show strong production growth continuing for the foreseeable future. —Newell and Raimi.

The cash incentive for consumers would be available to offset the higher upfront costs of electric cars , in particular the price of the batteries in modern vehicles. The government also wants to find ways to support the ongoing costs of electric cars. "We benefit, broadly, manufacturing in the UK," said Hoon. My Web del.icio.us

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

As the lithium surface is well passivated by LiNO 3 additive in ether solvent, internal shuttle effect is largely eliminated and thus excellent performance over 2000 cycles is achieved with a constant capacity of 200 mA h g ?1. Energy Environ. 1 can be achieved. 6, 1552-1558 doi: 10.1039/C3EE00072A.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

A new report from the UN Environment Programme (UNEP) projects that by 2050, hydrofluorocarbons (HFCs) could be responsible for emissions equivalent to 3.5 W m -2 relative to 2000. Source: UNEP. Click to enlarge. By 2050, the buildup of HFCs is projected to increase radiative forcing by up to 0.4

EIA Annual Energy Outlook explores implications of behavior and demographics on light-duty vehicle energy demand

Green Car Congress

The Low VMT case assumes an environment in which travel choices made by drivers result in lower demand for personal vehicle travel, consistent with the recent trend. When labor force participation rates rise, VMT per driver is likely to increase, particularly for millennials (those born between the early 1980s and early 2000s).
