Study finds half of the world’s population exposed to increasing air pollution

Green Car Congress

A team of researchers, led by Professor Gavin Shaddick at the University of Exeter, has shown that, despite global efforts to improve air quality, half of the world’s population is exposed to increasing air pollution. In some regions, sand and desert dust, waste burning and deforestation are additional sources of air pollution.

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). High pollution across the entirety of Bangladesh makes it the most polluted country in the world.

IEA finds CO2 emissions flat for third straight year even as global economy grew in 2016

Green Car Congress

This was the result of growing renewable power generation, switches from coal to natural gas, improvements in energy efficiency, as well as structural changes in the global economy. The biggest drop came from the United States, where carbon dioxide emissions fell 3%, or 160 million tonnes, while the economy grew by 1.6%.
