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.

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.

Rapid motorization is creating more congestion, air pollution, traffic accidents and greenhouse gas emissions—especially in developing countries. Many large Asian cities also suffer from the highest air pollution levels in the world, contributing to the premature death of half a million people each year.

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.
