Air pollution is the UK’s largest environmental health risk – greater than obesity and smoking.

It leads to 40,000 early deaths a year and costs the UK economy a staggering £20 billion annually.

Without stronger action to reduce exposure to toxic air, the number of deaths and the costs will, sadly, increase. 

Air pollution is preventable, but as it is a silent and invisible killer, not enough is being done in the UK.

EV-only cities?

The World Health Organization (WHO) has now completed a review of the guideline air quality levels it set in 2006 and has published much stricter limits.

Significantly, the WHO has cut by 50% the air quality guideline limit for fine particulate matter (PM2.5) and has slashed by 75% the limit for nitrogen dioxide (NO2). The current legal limits in the UK for these pollutants are disturbingly high.

‘As health effects have been found even at the lowest levels of PM2.5 that have been measured, and well below the previous WHO Guidelines of 10 µg/m3, we welcome these stricter WHO limits, which if implemented in UK law should help protect outdoor workers from toxic air.

‘As the main source of pollution in our cities and built-up areas is road traffic, the government must now go further to reduce emissions from petrol- and diesel-powered engines. So, the prime minister should adopt a policy of allowing electric only vehicles in our cities from 2030.’

Chief executive of the British Safety Council

An occupational health issue

While toxic air is potentially harmful to everyone, the risk of exposure is greater for outdoor workers, for whom the street is their workplace. This means ambient air pollution must be fully recognised as the occupational health issue it is.

For many outdoor workers in the UK, the shocking reality is that drawing breath during their working day is shortening their life. For them, ambient air pollution has turned the simple, human act of breathing into a deadly occupational hazard.

This forgotten army of outdoor workers delivers our letters and online shopping, help our children to cross the road, empty our bins, clean our streets, drive public transport, maintain our essential services, police our traffic or work on or near busy roads. They deserve better protection.

UK air pollution limits

British Safety Council is urgently calling on the government to act now on setting robust legal limits in the UK without delay, using these stricter WHO limits as a minimum.

Unsafe air is not something society should simply accept. The benefits of pollution control far outweigh the costs. No one should be made ill by the job that they do.
