Stationary energy
This sector includes emissions from energy consumption in buildings, including electricity and natural gas, and energy use in manufacturing and construction.
It generates 26.6 per cent of Auckland’s total emissions.
Industrial processes and product use
This sector consists mostly of non-energy related GHG from industrial processes, which in Auckland, are associated with steel production.
GHG emissions from industrial product use are mainly associated with the use of hydrofluorocarbons (HFC) and perfluorocarbons (PFC) which are used as refrigerants in air conditioning units and refrigerators.
This sector generates about 20.2 per cent of Auckland’s total emissions.
Agriculture
Agriculture emissions include methane and nitrous oxide from livestock, animal wastes and fertiliser use. Agricultural energy use, such as for heating greenhouses, is classified differently and sits under the Stationary energy sector.
This sector generates about 6.4 per cent of Auckland’s total emissions.
Waste
Emissions from landfilled waste and wastewater treatment are reported for this sector, with emissions from decomposing waste in landfills responsible for most reported emissions.
This sector generates about 3.1 per cent of Auckland’s total emissions.
