2023年2月10日 · The first year of the Ultra Low Emission Zone (ULEZ) expansion to inner London has achieved a dramatic reduction in emissions and air pollution, and a huge increase in the share of vehicles that...

2025年3月7日 · Particle emissions (PM 2.5) from vehicle exhausts, are 31% lower in outer London in 2024 than they would have been without the ULEZ expansion. [2] The environmental impact of ULEZ has been substantial, with carbon emissions equivalent to nearly three million one-way passenger trips between Heathrow and New York saved [3]

2023年8月24日 · A study by researchers at Imperial College London published in the journal Environmental Research Letters in November 2021 assessed the impact of the ULEZ in the first five to eight weeks after it was introduced in April 2019. This analysis showed widespread, but relatively small, reductions, and some increases, in air pollution ...

2024年7月25日 · A major new report from City Hall shows the ULEZ expansion is working better than predicted, with London’s air quality continuing to improve at a faster rate than the rest of England and...

2022年12月1日 · The estimated effects show that both the Toxicity Charge and the ULEZ have had a significant impact on reducing NO 2 emissions, as measured by roadside and background stations within the CCZ. Moreover, our results are robust to differentiating by type of day.

2022年7月19日 · Transport for London (TfL) found no change in levels of pollutants since ULEZ expanded to the North and South Circular roads in October 2021. But roadside nitrogen dioxide levels in the expanded...
