In 2021, Prof John Currie and Natalie Reguis were asked to do a report commissioned by the City of Edinburgh Council to look at CO2 levels and ventilation in different schools around the city. The report found that some classrooms had CO2 levels as high as 2,810ppm, while one music room had concentrations of 1,990ppm.
The research took place between November 2020 and February 2021 across nine out of 123 primary schools. More widely, the Scottish Government asked local authorities across the country to assess CO2 concentrations in learning, teaching and play spaces.
In February 2022, this report was brought up at the Scottish Parliament. In April 2022, this same report has been mentioned another time. See article in the Byline Times.
