There seems to be a connection between indoor air quality in classrooms and school results in Sweden. EFA member Swedish Asthma and Allergy Association went through the country's best schools list in 2017 and compared them with the list of municipalities benefitting from a state subsidy for school shelters 2015-2016. The result is that five of ten municipalities on the Swedish top-list schools had applied for the subsidy, that helps improving air quality indoors.
“There are many factors that make a school successful, and caring for indoor climate and fresh air for the kids may be one”, EFA members suggests in their article. This is one of the reasons why the Swedish Asthma and Allergy Association asked in February for an extended and improved contribution of the state subsidy to schools and an easier applying process at national level.
