New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. Tailing ponds are not the end of the journey for the pollutants they contain. —Parajulee and Wania.

Satellite altimeter data study finds global ship traffic up 4x over past 20 years

Green Car Congress

Maritime traffic on the world’s oceans has increased four-fold over the past 20 years, likely causing more water, air and noise pollution on the open seas, according to a new study quantifying global ship traffic. Ships powered by fossil fuels dump oil, fuel and waste into the water and pump exhaust into the air.

Commercial Shipping Emits Almost Half As Much Particulate Pollution as Total Released by World’s Cars

Green Car Congress

Globally, commercial ships emit almost half as much particulate matter pollutants into the air as the total amount released by the world’s cars, according to a new study led by NOAA and the University of Colorado at Boulder. Ship pollutants affect local air quality and the health of people living along coastlines.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

Since substantial coal use (equivalent to 50% of global coal consumption) is the primary reason for the poor air quality, China is considering setting a cap on its use. In February 2012, the China State Council approved its first national ambient air quality standard for PM 2.5 , which will come into effect by the end of 2015.

Study finds using biofuels in shipping could reduce sulfate aerosols by up to 40-60%

Green Car Congress

Utilizing biofuels as a substitute for heavy fuel oil in the current (2006) global shipping fleet would result in strong reductions in sulfate aerosol of up to about 40-60%, according to a new study by a team from Germany and Hawaii. This clearly has positive consequences for pollution reduction in the vicinity of major harbors.
