London, a bustling urban hub, faces significant pollution challenges from vehicles, industrial activities, and fossil fuel use. These environmental threats not only endanger public health but also hinder the city's sustainable development goals.

This thesis explores how integrating trees and green spaces into London’s urban environment can mitigate pollution and enhance urban life. Nature-based solutions, particularly trees, can absorb pollutants, reduce carbon emissions, and improve air quality. Additionally, green spaces foster physical and mental wellbeing, promote social cohesion, and support biodiversity.

In response to these challenges, the Mayor of London has launched a £3.1 million tree planting initiative to combat climate change. The initiative aims to increase the city’s tree canopy from 21%, focusing on underserved areas and vulnerable populations, with goals of cooling the city, reducing flood risk, and enhancing carbon absorption. By incorporating green spaces into urban planning, London can create a more sustainable, resilient, and human-centred environment, addressing pollution while ensuring a healthier future for all.
