From the executive summary

Te-Tāruke-ā-Tāwhiri: Auckland's Climate Plan sets the target of net zero emissions by 2050 with an interim emissions reduction target of 50 per cent by 2030 (against a 2016 baseline). An emissions inventory provided at a suitable frequency identifies and quantifies the most recent sources and sinks of greenhouse gas (GHG) emissions and trends. This provides a robust evidence base and essential data to evaluate impacts of mitigation actions, progress against the targets, frame further mitigation actions and inform future policy development. In addition, it provides input to the state of Auckland’s environment reporting.

This inventory was prepared using the relevant international guidance and best practices, including the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC) which is a globally recognised standard consistent with IPCC guidelines.

Auckland’s GHG inventory was first compiled for 2009, and the last release was for 2019. This current inventory reports GHG emissions and carbon removals within the Auckland region for the period 2009-2021. In 2021, Auckland’s gross emissions were 10,757 kilo-tonnes of carbon dioxide equivalent (kt CO₂e) and when land and harvested wood products (HWPs) were included, net emissions were 9,559 kt CO₂e. Transport and stationary energy are the dominant sectors, accounting for 49.2 per cent and 22.6 per cent of gross emissions, respectively (Figure E-1). Carbon dioxide (CO₂) contributed 84.9 per cent, methane (CH₄) 8.1 per cent, nitrous oxide (N₂O) 2.9 per cent and other GHGs 4.1 per cent. ...
