New Brunswick schools have dramatically increased carbon dioxide monitoring, with 91 percent of facilities now equipped with the required sensors. Premier Susan Holt announced the milestone, marking a significant improvement in indoor air quality tracking across the province's education system. The monitoring expansion helps schools manage ventilation and air quality, which is important for student health and learning environments. Better CO2 monitoring can also inform energy efficiency decisions by showing when spaces need more fresh air versus when heating or cooling energy is being wasted. This kind of practical environmental monitoring at the community level shows how carbon dioxide tracking can serve multiple purposes from health to energy management. It is a concrete example of climate-related infrastructure being deployed in public buildings.
