Putting a price on pollution, hello, you're listening to the Marketplace Morning Report

from the BBC World Service, I'm Vivian Nunes, good morning.

Poor air quality is being described as one of the greatest risks to human health, according

to a new study by the Energy Policy Institute of Chicago.

That's particularly bad news for people living in South Asia, with Bangladesh, India, Nepal,

and Pakistan the most polluted countries.

The BBC's Samira Hussein has been looking at the report.

Most of the negative impacts of air pollution on life expectancy is concentrated in just six

countries.

In India, for example, the effects are particularly acute, where just the act of breathing poor

air can wipe 5.3 years off the life expectancy of the average Indian.

Since 2013, about 59% of the global increase in pollution has come from India alone.

Here in the UK, London has today expanded its ultra low emission zone or U-LES, which

is designed to clean up air quality in the English capital city.

It means daily charges of around $16 for those driving the oldest, most polluting vehicles,

despite growing political opposition.

It's now the largest pollution charging zone in the world.

Here's the BBC's Oledel-Butansson with more details.

Today's expansion means those driving older, more polluting vehicles in any part of London

will have to pay $16 a day for the pleasure.

It could add up to $5,000 a year to your outgoings if you live there.

Not every car is affected though.
