Auckland’s vision is to become the world’s most liveable city. The Auckland Plan lays out an aspirational target to achieve a 40 per cent reduction in greenhouse gas (GHG) emissions by 2040 (based on 1990 levels). Auckland Low Carbon Action Plan sets out the pathways and specific actions to achieve the target. Reducing Auckland’s GHG emissions is a critical element to achieving this vision. An inventory that identifies and quantifies the sources and sinks of GHGs in Auckland is essential to inform and evaluate our progress.

Auckland’s GHG inventory for 2013 and 2009 was prepared with the most up-to-date information and in accordance with the global best practice: the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC). In 2013, Auckland’s GHG emissions were 11,997 ktCO2e (kilo-tonnes of carbon dioxide equivalent) (gross emissions) or 10,955 ktCO2e (net emissions including carbon sequestration from forestry). Of the three GHGs estimated, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) contributed 81.3 per cent, 16.5 per cent and 2.1 per cent of the gross emissions. ...
