Aggregate data about the emission of air pollutants especially those potentially harmful to human health (although it is not a requirement to include information on greenhouse gas emissions). Aggregate means national-level or available for at least three major cities. In order to satisfy the minimum requirements for this category, data must be available for the following pollutants and meet the following minimum criteria:
- Particulate matter (PM) Levels
- Sulphur oxides (SOx)
- Nitrogen oxides (NOx)
- Volatile organic compounds (VOCs)
- Carbon monoxide (CO)
- Updated on at least once a week.
- Measured either at a national level by regions or at leasts in 3 big cities.
Air quality data is gathered by regional councils and aggregated by Ministry for the Environment annually. Some councils, such as ECAN, make realtime air quality data available (see https://data.ecan.govt.nz/Catalogue/Search?Query=&CollectionId=4 ).
The 2014 report "includes data to 2012. Data for 2013 was not available for all our national indicators and case studies, or could not be collected, validated, and analysed in time to meet our publication schedule."
