Glasgow Forestry and Woodlands Strategy features attributions by trees for improving air quality
Quote:
"Air pollution can impact human health and contribute to respiratory conditions such as asthma, especially amongst young people and those with a chronic illness. In addition to having an adverse impact on human health, air pollution in the form of chemical (e.g. Nitrogen Dioxide) and particulate pollutants, can also be detrimental to ecosystems and habitats.
In 2018, to improve air quality, Glasgow City Council introduced Scotland’s first low emission zone (LEZ) broadly covering the city centre. The first of the two phases sought reductions in emissions from scheduled bus journeys, and the second, introduced in June 2023, restricts access for the most polluting vehicles to protect public health and support wider climate change ambitions by encouraging more sustainable transport options.
Trees can help to improve air quality in several ways, such as creating a physical barrier between pollutants and people, while also removing particles from the air, which, in turn, can, reduce the adverse impact on human health and habitats."
