Urban forests create a sense of place and well-being where people live, work, play, and learn and help mitigate climate change and improve air quality. Trees are also crucial for places characterized by warm climates. In this regard, FAO1 reports that the strategic placement of trees in cities can help lower the air temperature by two to eight degrees Celsius, making that sticky urban heat just a little more bearable. Additionally, large trees are also excellent at absorbing pollutant gases and filtering fine particulates such as dust, dirt or smoke out of the air by trapping them on their leaves and bark.
The European Environment Agency conducted a study in 2021 to determine the air quality among 323 cities across the continent over the past two years. According to this research, Milan, Italy, was ranked 303 as one of the most polluted cities in Europe with an average level of fine particulate matter (PM2.5) twice as high as the standard set by the World Health Organization2.
However, The Municipality of Milan has been trying to improve the air quality of the city by promoting initiatives like Forestami, a research project carried out by the Polytechnic University of Milan. The study analysed and assessed the state and percent of coverage of the natural greenery in the two-year period 2018-2020, arriving at an estimated Tree Canopy Coverage (the surface area occupied by tree crowns over the entire territory) of 16%3. This was the starting point for Milan to be recognised by the Tree Cities of the World programme as one of the 120 cities in the world committed to ensure that their urban forests and trees are properly maintained, and sustainably4.
