Tallinn in top ten cleanest capital cities

According to a report by the World Health Organisation, the Estonian capital, Tallinn, is among the least polluted capitals in the world.

The report suggests that pollution poses a greater threat to human health than HIV and Ebola.

Writing on the report, the British daily, the Telegraph, said that based on levels of PM 2.5 – tiny pollution particles that measure two and a half microns or less in width – the Saudi capital, Riyadh, is the most polluted capital on Earth, followed by New Delhi, India, and Doha, Qatar.

Using the report’s data, the newspaper compiled a list of the world’s least polluted capitals, in which Tallinn comes seventh.
