made under the

Climate Change and Greenhouse Gas Reductions Act 2010 s 11 (Measuring greenhouse gas emissions – determination)

1	Name of instrument
This instrument is the Climate Change and Greenhouse Gas Reduction (Greenhouse Gas Emissions Measurement Method) Determination 2011.
2	Commencement 
This instrument commences on the day after it is notified. 
3	Determination of method for measuring greenhouse gas emissions
I determine the method for measuring the amount of greenhouse gas emissions in the ACT for the year (the annual emissions amount) as set out in the schedule attached to this instrument.

1.	Objects of the determination

This determination sets out the method for the measurement of greenhouse gas emissions arising from sources, and attributable to activities located within, the geographic boundary of the Australian Capital Territory (ACT). 
2.	Application of the determination

The method determined in this instrument must be used to measure the amount of greenhouse gas emissions in the ACT for the year (the annual emissions amount) in the annual report prepared by the independent entity as required under section 12 of the Act.
3.	Emissions covered

The emissions covered by this determination are:
•	Scope 1 emissions from:
•	fuel combustion
•	fugitive emissions from fuels 
•	industrial processes 
•	agriculture 
•	land use, land use change and forestry, and
•	waste.
•	Scope 2 emissions from the consumption of electricity.
•	Scope 3 emissions from electricity transmission and distribution losses.
The annual data on these emissions will be obtained from the National Greenhouse Accounts except for the following:
•	indirect electricity
•	natural gas consumption
•	wood fuel combustion, and
•	road transport.
4.	
Method

The method for calculating the emissions for which annual data will not be obtained from the National Greenhouse Accounts will be made using the following equations:
Equation 1: Stationary energy combustion emissions – indirect electricity

Where:
EIE  is emissions from electricity consumption expressed in tonnes of CO2-e
DL is the distribution loss factor for ActewAGL Distribution for the relevant financial year
TL is the transmission loss factor for electricity supplied to the ACT for the relevant financial year
QE  is the consumption of purchased electricity expressed in kW hours
GP  is the consumption of purchased GreenPower expressed in kW hours
EFE  is the emissions factor for scope 2 electricity consumption for NSW/ACT in kilograms of CO2‑e emissions per kilowatt hour.

Equation 2: Stationary energy combustion emissions – natural gas

Where: 
ENG  is emissions from natural gas consumption expressed in tonnes of CO2-e
QNG  is the consumption of purchased natural gas less consumption by ACTION Buses expressed in megajoules
EFNGj  is the emissions factor for natural gas combustion for greenhouse gas type   j = CO2, CH4 and N2O in kilograms of CO2‑e per gigajoule 

Equation 3: Stationary energy combustion emissions – wood fuel

Where: 
EWF  is emissions from wood fuel consumption expressed in tonnes of CO2-e
QWF  is the consumption of dry wood expressed in tonnes
ECWF  is the energy content factor for dry wood expressed in gigajoules per tonne
UWFi  is the share of wood fuel consumption used in activity type i = heating and stoves
EFWFij  is the emissions factor for activity type i for greenhouse gas type j = CH4 and N2O in kilograms of CO2‑e per gigajoule

Equation 4: Transport fuel emissions – road transport

Where: 
ERT  is emissions from road transport vehicles expressed in tonnes of CO2-e
QRTi  is the quantity of transport fuel type i = petrol, diesel, and LPG sold measured in kilolitres and CNG consumed by ACTION Buses expressed in cubic metres.
ECRTi  is the energy content factor for transport fuel type i expressed in gigajoules per kilolitre or gigajoules per cubic metre
EFRTij  is the emissions factor for transport fuel type i for greenhouse gas type j  = CO2, CH4 and N2O in kilograms of CO2‑e emissions per gigajoule
