The following is an article written by Richard Walker which explains the likely impact of the ULEZ expansion on life expectancy.
ULEZ EXPANSION COULD INCREASE LIFE EXPECTANCY BY 2.4 DAYS – MAYBE!
Yes, instead of 81 years, or 29,565 days, it could rise to 29,567 days, an increase of 0.008% !!!!
Mayor Khan has been reluctant to put numbers to the health benefits of expanding ULEZ to outer London, but a report by the Committee on the Medical Effects of Air Pollutants, COMEAP NO2 2018 (Google it) reveals on page 69 that a 1 μg/m3 reduction in NO2 emissions should increase life expectancy by 8 days.
The official Jacobs Integrated Impact Assessment estimates (p47) that ULEZ expansion will reduce NO2 pollutant levels by just 0.3 μg/m3 in outer London. 0.3 x 8 = 2.4, so that gives a 2.4 day lifetime increase thanks to ULEZ, or + 0.008%.
Thank you, Mr Khan, but in no way can that pathetic benefit justify the pain your scheme will inflict on us.
Khan’s repetitive public statements about NO2 hazards are based on a health burden report which in turn is based on the COMEAP report published in 2018 where there was no consensus on the details and which is now out of date, plus the Jacobs Impact Assessment for the ULEZ.
The following diagram shows the overall financial impact of the ULEZ expansion:
