Reducing levels of air pollution by 20% could have a positive impact on children's ability to learn, according to new findings.
It's all part of the Clean Air for Schools Programme which is a research project headed up by the Global Action Plan, the Philips Foundation and the University of Manchester.
The programme looks at how indoor and outdoor pollution effects children and how it can be tackled in schools across the UK & Ireland.
The findings suggest lower pollution levels could improve a child's working memory by 6%, which is equal to about four weeks extra learning time per year.
Air quality data from the Department for Environment, Food and Rural Affairs (DEFRA) revealed air pollution levels may have dropped by around 40% across the UK during April and May when lockdown was in full force earlier this year.
The organisations involved in the clean air programme would now like to see these lower air pollution levels maintained which they believe will benefit children.
"Pollution of indoor and outdoor air affects the health of our children," said Martie van Tongeren who is a a professor in Occupational and Environmental Health, University of Manchester.
"We've spent a year investing how to improve air quality in and around schools which will benefit child's health and educational development and should be a priority for government, local authorities and schools."
"...if we all try and change our habits, and in particular, walk and cycle for as many of our shorter journeys as we can, then we'll reduce congestion and improve air quality," said Eleanor Roaf who is the Director of Public Health for Greater Manchester.
