10-year study shows how air pollution fosters heart disease; accelerated plaque build-up in arteries

Green Car Congress

Long-term exposure to particulate air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. Repeated scans were done for nearly all participants between 2002 and 2005; for a subset of participants between 2005 and 2007; and for half of all participants between 2010 and 2012.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems.

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. The research used satellite altimeter data to estimate the number of vessels on the ocean every year between 1992 and 2012.

Requiring Lower Sulfur Marine Fuels Could Reduce Emissions-Related Deaths by Up to 50% Annually By 2012

Green Car Congress

Sulfur (1,000 ppm) content within 200 nautical miles of coastal areas could reduce annual premature deaths resulting from emissions-related affects by around 43,500 by 2012—approximately 50% of the 87,000 deaths estimated to occur in a no control scenario (assuming 2.7% S (35,000 ppm) in 2012 and 0.5% and (c) Global 0.5.
