Surprise! #London's tax on #polluting #vehicles made everyone much healthier
Two of the most dangerous aspects of vehicle #emissions – nitrogen oxides, which are responsible for #smog formation, and PM2.5, which are tiny particles that irritate the lungs – have dropped by almost a third compared to if #ULEZ hadn’t been implemented, in only the few years that the policy has been in place.
99% of air quality monitors around London have showed a reduction in #pollution!

London’s low emission zones save lives and money, new study finds

New research from the University of Bath has revealed that Greater #London's #cleanAir policies—the Low Emission Zone (#LEZ) and the Ultra Low Emission Zone (#ULEZ) are not only improving the city’s environment but are also delivering significant measurable #publicHealth and economic benefits.

Transport for London's #ULEZ scheme cleaned London's air:

"The findings highlight the success of transport interventions, such as the London Low Emission Zone and the Ultra Low Emission Zone (ULEZ), in significantly reducing #NOx emissions from vehicles."

London Begins to Breathe Better

[Read on Ethical Revolution]

A study by the Greater London Authority has shown that the city’s levels of lethal pollutants have substantially decreased since the expansion of the UK capital’s ultra low emission zone (Ulez).

The London-wide zone covers nine million people across 1500 km2, the world’s largest zone of its kind. 

The report shows that not only have deprived areas seen some of the biggest improvements but air quality has improved in all areas and at a faster rate than the rest of the country.

Nitrogen dioxide is down 27% since Ulez first came in in 2019. PM2.5’s (small particle emissions) are down 31% in outer London compared to what would have been without the Ulez expansion.

Speaking to the Guardian, Mayor of London, Sadiq Khan said, “When I was first elected, evidence showed it would take 193 years to bring London’s air pollution within legal limits if the current efforts continued. However, due to our transformative policies we are now close to achieving it this year.”
