International travelers experience adverse cardiopulmonary health effects even after short stay in polluted cities

Green Car Congress

For travelers who visit cities with high levels of air pollution, even a short stay leads to breathing problems that can take at least a week from which to recove, a new study led by researchers at NYU School of Medicine finds. The study is the first of its kind, say the authors, to analyze pollution-related coughing and breathing difficulties and recovery times upon returning home, in healthy, young adults who’ve travelled internationally.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C The team considered about 400 emission control measures to reduce these pollutants by using current technology and experience. National benefits of the CH 4 plus BC measures versus the reference scenario.

Air pollution is the leading environmental cause of death worldwide according to the State of Global Air 2018 , the annual report and interactive website published by the Health Effects Institute (HEI). Ozone, another important component of outdoor air pollution, whose levels are on the rise around the world, contributed to 234,000 deaths from chronic lung disease. All told, long-term exposure to outdoor and indoor air pollution contributed to 6.1

Global CO2 emissions stalled for the third year in a row

Green Car Congress

Emissions from international transport (aviation and shipping) contribute another 3% to the total global GHG emissions. Emissions are increasing in other developing countries: 6% for Indonesia and Malaysia; 9% for Pakistan and 12% for the Philippines. The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO 2 emissions have stalled for the third year in a row.

2018 Environmental Performance Index: Air quality top public health threat

Green Car Congress

Recent research cited by the EPI suggests that around five million people die prematurely every year due to air pollution, accounting for approximately one in every ten deaths annually. Substantial populations still suffer from poor air quality, most notably in India, China, and Pakistan. The 2018 Environmental Performance Index (EPI) finds that air quality is the leading environmental threat to public health.

Global energy-related carbon dioxide emissions were flat for a third straight year in 2016 even as the global economy grew, according to the International Energy Agency. The overall increase in the world’s nuclear net capacity last year was the highest since 1993, with new reactors coming online in China, the United States, South Korea, India, Russia and Pakistan.
