Methodology description

This dataset provides consumption-based emission intensities (tCO₂e per dollar of expenditure) for New Zealand, developed by Market Economics Limited for Auckland Council. The emission intensities are calculated using a top-down Input-Output (IO) approach, drawing primarily on Statistics New Zealand's 2020 Inter-industry Study of the New Zealand Economy and the 2019 Production-based GHG Emissions Accounts. Using Supply-Use Tables from the inter-industry study, consumption emission intensities are produced for 199 commodities, which can be linked to the Household Economic Survey to provide a direct connection to commonly purchased household items. Emissions data is based entirely on domestic datasets; goods and services purchased from outside New Zealand are assumed to generate the same emissions per dollar of expenditure as equivalent goods and services produced domestically.

Climatiq has extracted spend-based emission factors for New Zealand from two sheets in the accompanying dataset file:

Cons EF 247 NZHES — emission factors mapped to 247 New Zealand Household Expenditure Survey categories. Cons EF 199 SUT — emission factors at the 199-commodity Supply-Use Table level.
