Consequently, no statistics are available on the contribution of major sources by sector to the city’s air pollution. Even though the implementation of the automated environmental monitoring system for major emission units was mandated in the Environmental Protection Regulation and Decree No. The city will need to work with the Department of Industry and the Department of Natural Resources and Environment to make a roadmap and allocate sufficient resources to systematically install real-time monitoring stations (air and water) at major IZs, ICs and the port, to identify and measure major pollutants and make the information accessible to public.
