Measure the impact of policies designed to reduce air pollution in two major towns


For the first time, an investigation into air pollution in two rust cities – London and Paris – has been measuring the impact of policies designed to reduce air pollution from urban traffic over the last 12 years.

In a newspaper, published today in the publication Environmental pollution, researchers from King's College and London Airparif, despite efforts, suggested that the two towns were not meeting legal boundaries for the pollution of nitrogen dioxide and substances away from body. t World Health.

There are many policies in place to combat air pollution at European, city and local levels. This study found that these have led to 2010 improvements in the density of nitrogen dioxide and fragments of both towns.

However, the level of change was not sufficient to comply with legal boundaries. They are aware that dioxin nitrogen from London traffic has declined alongside some roads.

Looking at two times, 2005-2009 and 2010-2016, they also found:

  • As the legal compliance was coming in 2010, nitrogen dioxide in the two towns was getting worse and not better. Despite going through an experimental laborer, new diesel cars couldn't reduce the expected decline when they drove them on the roads t . This suggests that if feedback from air pollution monitoring and better policy makers was available, that could have given a more flexible response, as issues have changed from the exposure point of view. T expected.
  • From 2010 to the end of 2016, the huge decline in shark pollution in London and Paris can be explained by applying Euro 5 standards to cars and diesel vans.
  • There is some evidence that the introduction of diesel lorries and new buses started after 2009 has reduced nitrogen dioxide.
  • In London, schemes to upgrade the bus fleet are leading to rapid improvements along some roads. However, motorcycle cycles in London from 2010 could increase some of the improvements from other vehicle types. This indicates the strict limited levels for motorcycles compared to other vehicles.

Dr Gary Fuller, atmospheric pollution scientist at King's College London, said, "The scandal was a major influence on diesel emissions from air pollution in two European cities. This has caused problems t and the broadest limits for the extraction of nitrogen dioxide.

“Clear aims here are a need for better feedback to ensure our air pollution policies are being restored. There are some successes in London and especially the bus. Although we are now on the right path, we need stronger policies. , as the forthcoming low-level distribution zone in London, to improve air pollution rapidly for all our towns, and we need to make sure they work.
