The carbon methodology and model underpinning Future Fit is primarily based on work conducted by the Motu Economic and Public Policy Research, which has been adapted for FutureFit.
FutureFit calculates the tonnes of carbon represented in your personal carbon footprint by using a mix of New Zealand-based emission and household spending data, along with the personal information you enter, such as household size and income.
We have used a consumption-based approach to calculate emissions embodied in final products and services. This approach combines information on energy use by industry, energy emissions and process emissions, along with the total requirements data from input–output tables.
Motu’s methodology uses Statistics New Zealand’s input–output tables and New Zealand emission factors, together with the New Zealand Household Economic Survey to estimate the emissions associated with each household’s consumption across a range of products and services.
The FutureFit team are responsible for the emission calculations used in this tool. Updates to the FutureFit model will be undertaken where practicable, as new research becomes available.
This approach allows us to see a more direct relationship between consumer choices and the resulting estimated emissions (than production-based emission calculations); which is useful in helping people to make informed choices. Building on this, the FutureFit model allows you to enter detailed information about how you use or consume various products and services to get a personalised overview of how much carbon you are emitting, and from which of your activities it is from.
In FutureFit your personal carbon footprint starts at the New Zealand average (it doesn’t start at 0), then is tailored to you - it increases or decreases as you answer questions about your lifestyle. Completing the Next Level questions will give you the most accurate footprint result. Your carbon footprint at the start, as well as your current footprint will show on your dashboard. As you complete FutureFit actions each week your footprint will reduce.
We would like to extend a big thank you to Paul Young, Senior Analyst, Climate Directorate, Ministry for the Environment; and Luitgard Schwendenmann, Associate Professor, Auckland University, for their tireless work and commitment to building the robust, flexible and dynamic model that underpins this web application. We would also like to acknowledge the support provided by Corey Allan during his time at Motu Economic and Public Policy and Research.
