A University of New South Wales (UNSW) report measures air quality in NSW schools and finds ventilation issues in a subset of classrooms. The study assesses conditions across 59 schools using monitoring devices installed in classrooms. It reports that 17 classrooms record carbon dioxide (CO2) concentrations that are not considered optimal for learning. The outlets describe this as an indicator of ventilation performance, with higher CO2 levels typically associated with reduced fresh-air intake and greater build-up of exhaled air. The reporting is based on the findings from the monitoring program and focuses on the proportion of monitored classrooms that did not meet recommended CO2 thresholds. While the articles agree on the overall numbers—59 schools monitored and 17 classrooms with non-optimal CO2 levels—they do not provide further breakdowns such as which schools were affected, how long measurements were taken, or what specific actions schools may take in response. Overall, the coverage presents the UNSW measurements as evidence that some classroom environments in NSW fall short of desired air-quality conditions for learning.
