- Please supply evidence backing the above.
Our response
The independent Integrated Impact Assessment (IIA) for the London-wide ULEZ proposals
assessed potential health, environment, equality, and economic impacts of the proposals on different groups and includes an equalities impact assessment.
The forecast number of deaths that would be prevented by a London-wide ULEZ is set out in Chapter 6.2 of IIA.
You may also be interested in the Air Quality Health Impact Assessment which can be found in Appendix A of the IIA.
Studies have long shown the many adverse health issues associated with elevated pollution levels.
A 2022 authoritative evidence review continued to show the health impacts of traffic
pollution, especially asthma in both children and adults.
Previous analysis has shown that London’s air pollution was estimated to lead to around 700 asthma hospital admissions from 2017-2019 in children in London, 7 per cent of all asthma admissions in children in London and to around 900 asthma or chronic obstructive pulmonary disease (COPD) admissions from 2017-2019 in the elderly in London.
The growing health evidence now links air pollution to dementia, shows how air pollution causes lung cancer in non-smokers and found particulate air pollution in unborn babies.
