"This dataset shows estimated annual emissions for different pollutants (tonnes per square kilometre): Particulate matter 10 micrometres or less in diameter (PM10); Particulate matter 2.5 micrometres or less in diameter (PM2.5); Sulphur dioxide; Sulphur Oxides (SOx); Carbon Monoxide (CO), and; Nitrogen Oxides (NOx).
- PM10 and PM2.5 are from home heating
- SOx are from Industrial sources
- CO and NOx are from road motor vehicles.
Data for PM10 (PM10_t_km_yr_) and PM2.5 (PM25_t_km_yr_) are provided for 2006 and 2013, including percent difference (PM10_PC_difference) and (PM25_PC_difference).
Data for CO (MV_CO_t_km_yr_) and NOx (MV_NOx_t_km_yr_) are provided for 2001 and 2013, include percent difference (MV_CO_PC_diff_01_13) and NOx (MV_NOx_PC_diff_01_13).
Data for SOx is for 2013 only (I_SOx_t_km_yr_2013).
Data is broken down by territorial authority area.
This dataset relates to various Environmental measurse on the Environmental Indicators, Te taiao Aotearoa website: home heating; road motor vehicle emissions, and industrial emissions.
