Each year about 6.5 million deaths worldwide are linked to air pollution, a number that could grow in coming decades unless the energy sector steps up its efforts to slash emissions, the International Energy Agency warned.
Air pollution -- including environmental and household air pollution -- has emerged as a leading risk factor for stroke worldwide, associated with about a third of the global burden of stroke in 2013, according to a new study.
A quarter of all global deaths annually are related to environmental pollution and the death rate is increasing significantly, the World Health Organisation warned in its latest report.
