AQLI: new data reveals little progress globally in reducing air pollution over the last two decades

Green Car Congress

Particulate air pollution continues to cut global life expectancy by nearly two years as progress in some countries counterbalances worsening air quality in others, according to the Air Quality Life Index (AQLI). China began a “war against pollution” in 2013.

Drivers from the world’s poorest cities who keep their windows down are exposed to 80% more air pollution

Green Car Congress

Car users from the world’s least affluent cities are exposed to a disproportionate amount of in-car air pollution because they rely heavily on opening their windows for ventilation, according to a new global study led by researchers at the University of Surrey. The study discovered that drivers in some of the world’s poorest cities experienced higher levels of in-car pollution.

pollution is significant, according to an analysis presented at ASN (American Society of Nephrology) Kidney Week. Standardized ABD (attributable burden of disease) in the 10 most populated countries showed Nigeria, Bangladesh, Pakistan, and India having high ABDs, exceeding 200 incident cases of CKD per 100,000 population.

New international Climate and Clean Air Coalition to focus on reduction of short-lived climate pollutants

Green Car Congress

Global benefits from full implementation of measures for reduction of short-lived climate pollutants in 2030 compared to the reference scenario. US Secretary of State Hillary Clinton announced the Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants, a new global initiative to seize the opportunity of realizing concrete benefits on climate, health, food and energy resulting from reducing short-lived climate pollutants.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot.

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

Analysis finds air-quality justification for CNG vehicle conversion in developing cities, despite negative climate impact

Green Car Congress

An analysis by a team in Bangladesh found large air quality and associated health benefits accruing to the residents of Dhaka (the capital of Bangladesh) as a result of the rapid conversion of the motor vehicle fleet to CNG. As the greenhouse gas impacts (costs or benefits) are much smaller than the health benefits, the conversion of petroleum vehicles to CNG can be justified on the basis of local air pollution benefits alone, they concluded.

ADB Transport Forum: shift to greener transport in Asia key to global sustainability; investment of $2.5T needed by 2020

Green Car Congress

Asia must scale up sustainable transport development or face a bleak future of congested roads, pollution, ill health and economic damage, which could have ripple effects around the world, the third ADB (Asian Development Bank) transport forum heard earlier this month in Manila. The epidemic of cars and trucks already weighs heavily, with Asia’s cities now suffering the highest air pollution levels in the world and traffic accidents in the region killing nearly 2,000 people a day.

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. India and Bangladesh come in near the bottom of the rankings, with Burundi, Democratic Republic of the Congo, and Nepal rounding out the bottom five. The 2018 Environmental Performance Index (EPI) finds that air quality is the leading environmental threat to public health.

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

While carbon dioxide is the primary driver of global warming over the long term, limiting black carbon and methane are complementary actions that would have a more immediate impact because these two pollutants circulate out of the atmosphere more quickly. 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.
