Mayor of London's Office has released new data showing that the introduction of electric taxis and buses, the ultra-low emission zone and other air improvement interventions since 2016, has had a massive improvement in lowered nitrogen dioxide (NO2) pollution in London.
In 2016, London’s air quality monitoring stations detected over 4,000 hours of NO2 levels in breach of EU Ambient Air Quality Directive limits. In 2019 the breaches of the hourly limit fell by 97% to only 100, and only from Westminster.
Greater London has seen a 21% average reduction in NO2 concentrations between 2016 and 2019, with substantial falls recorded in low emission bus zones.
The mayor of London, Sadiq Khan, said:
“Toxic air is a national health crisis contributing to thousands of premature deaths every year. I have taken bold action in London with measures such as the world’s first ultra low emission zone and low emission bus zones, and it’s undeniable that these are making a difference to the air we breathe. We’re doing all we can in the capital, with proven results, so there are no excuses left for the government’s failure to match our levels of ambition.”
