*Sources and Assumptions

Emission factors are taken from the MFE Measuring Emissions Guidelines, 2022. www.mfe.govt.nz Commercial and Default factors have been used where applicable. Transmission factors for electricity is included. Cars based on a manufactured date range of post 2015. Plugin Hybrid cars based on petrol or diesel km emission factors only. Bus based on >= 12,000kg. Passenger Rail based on Wellington “Average”. Radiative forcing has been used, and “Average Passenger” for flights. Gas reclamation has been used for waste. Exotic Planting based on 400 stems per hectare
