A pie chart and bar chart illustrating the share of emissions reduction in 2040 that relies on household low-carbon choices. The pie chart shows that 37% of emissions reduction comes from household choices, while 63% does not. The bar chart breaks down household-driven reductions: 42% from electric vehicles, 30% from low-carbon heating, 6% from reduced meat and dairy consumption, 1% from land-use changes due to diet shifts, 6% from maintaining current flying levels, 4% from energy efficiency in homes, 3% from modal shifts, and 8% from other smaller actions (e.g., waste reduction, recycling, efficient appliances).

Incredible findings on impact of LEZ & ULEZ ⬇️ significantly reduced PM10 & NO2 levels ⬇️ sick leave reduced by 18.5% ⬆️ improved general health ⬇️ reduced incidence of long-term health conditions and respiratory issues ⬆️ mental well-being & happiness 💷 est. savings exceeding £37 million per year

Air pollution poses a global concern due to its detrimental effects on climate, healthcare, and human capital accumulation. However, there is limited evidence on the health and human capital impacts of clean air transport policies. This study investigates the effects of London’s Low Emission Zone (LEZ) and Ultra-Low Emission Zone (ULEZ) on air quality, sick leave, well-being, and physical health. By exploiting the temporal and spatial variations of these policies – implemented in Greater London (LEZ) in 2008 and Central London (ULEZ) in 2019 – we implement a difference-in-differences approach utilising linked survey and administrative data. We show that the LEZ and ULEZ policies significantly reduced and levels. Consequently, we observe substantial improvements in labour productivity, with sick leave reduced by 18.5% from pre-LEZ levels. The ULEZ contributed to enhanced mental well-being, as evidenced by increased feelings of happiness, worthiness and satisfaction, along with a reduction in anxiety. These effects are further supported by improvements in physical health, with the LEZ reducing the incidence of long-term health conditions by 6.8% and respiratory issues by 10.2%. A back-of-the-envelope cost–benefit analysis suggests that the policies generated savings exceeding £37 million per year for the overall population.
