Providing good air quality in schools is vital for healthy learning. GNB has introduced capacity to measure air quality in all NewBrunswick schools by installing CO2 monitors that allow air quality to be monitored, recorded and analyzed. CO2 monitoringprovides a cost-effective indicator of ventilation effectiveness, which strongly affects overall indoor air quality.
New Brunswick has 295 schools in total. Schools designed after 2004 have more efficient systems to control indoor air quality.90 schools now have updated CO2 monitoring in place, representing 30.5% of all schools. By June 2026, all remaining schoolswill also have CO2 monitoring. By 2027, all schools will have ventilation systems. These measures and upgrades will help ensuregood indoor air quality, optimize system performance, and guide future improvements.
WorkSafe NB recommends that CO2 exposure less than 5,000 ppm for up to 8 hours, and below 30,000ppm for under 15-minutes, is considered safe.
All schools will have CO2 monitoring in place by June 2026 at which time targets will be set and a graph will be developed.
