Air emission inventories provide information about the amount of pollutants discharged into air from various pollution sources. They can be used to determine major sources of air pollutants, establish emission trends over time, support air quality policy development, and provide input for air dispersion modeling. This report estimates the emissions to air in the Auckland region from consented industrial sources with emphasis on emissions of five key ambient air pollutants (PM10, PM2.5, NOx, CO and VOCs) for the year 2011. Data were sourced from Auckland Council’s consent files and used to populate a database that has been used for two previous inventories (in 2006 and 2009). Data for existing industrial consents were updated. The outputs were compared to the two previous versions to identify industrial emission trends.
