China study connects ozone pollution to cardiovascular health

Green Car Congress

The study, by a team from Duke University, Tsinghua University, Duke Kunshan University and Peking University, appears in the journal JAMA Internal Medicine. The team studied 89 healthy adults living in Changsha City, China, for one year. They monitored indoor and outdoor ozone levels, along with other pollutants.

emissions, the NO x and SO 2 increases are significant enough to notably change total national emissions, they conclude.China has made a firm commitment to improve its air quality. 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 shipping emissions in East Asia contribute to up to 37.5K premature deaths each year

Green Car Congress

A study by a team of researchers from China and the US has shown that shipping emissions in East Asia accounted for 16% of global shipping CO 2 in 2013, compared to only 4–7% in 2002–2005. However, the climate and air quality impacts from shipping are not well understood in this region.

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.
