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.

Global CO2 emissions stalled for the third year in a row

Green Car Congress

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. Global GHG emissions continue to be dominated by fossil carbon dioxide (CO 2 ) emissions, which however show a slowdown trend since 2012, and were stalled for the third year in a row in 2016. Also in Eurasia emissions grew in Turkey (5%) and Ukraine (8%).

Study links air pollution and cyclone intensity in Arabian Sea; suggested solutions include diesel filters and two-stroke engines running on LPG fuel

Green Car Congress

Pollution is making Arabian Sea cyclones more intense, according to a study in the journal Nature. The aerosol buildup creates formations known as atmospheric brown clouds (ABCs) in which smog from diesel emissions, soot and other by-products of biomass burning accumulate and become widespread to a degree significant enough to affect regional climate. This underscores the importance of getting a handle on emissions in the region. Diesel Emissions Health India

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. All emissions control measures are assumed to improve air quality.

HEI: 95%+ of world’s population live in areas of unhealthy air

Green Car Congress

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 Emissions Health

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. In general, high scorers exhibit long-standing commitments to protecting public health, preserving natural resources, and decoupling greenhouse gas (GHG) emissions from economic activity. Substantial populations still suffer from poor air quality, most notably in India, China, and Pakistan.

UN Environment report says national GHG pledges only bring one-third of reductions needed for Paris Agreement

Green Car Congress

The eighth edition of UN Environment’s Emissions Gap report, released ahead of the UN Climate Change Conference in Bonn, finds that national pledges only bring approximately one-third of the reduction in emissions required by 2030 to meet climate targets, with private sector and sub-national action not increasing at a rate that would help close this gap. Given currently available carbon budget estimates, the available global carbon budget for 1.5 ˚C
