Study reveals green screens reduced air pollution levels in schools by 44%
A University of Surrey study has revealed that installing a green screen at schools in London helped reduce pollution levels by 44%.
Green screens are purpose-built structures designed to capture pollution, made by covering a metal frame fence with foliage.
Other interventions were also measured in the research, including closing the streets directly outside schools at drop-off and pick-up times which reduced pollution levels by 36%.
Hannah Battram from Global Action Plan spoke to James Dickman about the findings.
