The review finds that ambient air quality in the Highveld Priority Area (HPA) has not shown significant improvement since 2012, with frequent exceedances of National Ambient Air Quality Standards (NAAQS). Industrial sources remain the dominant contributors of SO2 and NOx, while mining is the primary source of PM10. An audit of the AQMP implementation reveals that less than 50% of interventions have been fully achieved, with significant deficiencies in vehicle emissions, waste management, and low-income settlement interventions. While government organizational capacity and awareness have improved, the report recommends a revised plan with SMART goals and strengthened cooperative governance across national departments.
