Global Warming Potential
> Different greenhouse gases have different heat retaining or insulating ‘strengths’
> This ‘strength’ is commonly known as the global warming potential (GWP) of a greenhouse gas.
GWP
Carbon dioxide equivalents
> Greenhouse gases are measured in carbon dioxide equivalents
CO2-e> Carbon dioxide equivalent is “a measure used to compare the
emissions from various greenhouse gases based upon their global warming potential”. (OECD)
CO2-e = mass of gas (kg or t) x GWP

Accounting methodologies – GHG Protocol
The Greenhouse Gas Protocol - A Corporate Accounting and Reporting Standard
> a standard> defines boundaries> defines scopes> reporting and much more . . .> from: WRI/WBCSD> www.ghgprotocol.org/standards/corporate-
standard
Operational boundaries - Scopes
Defines which emissions sources are included or excluded and their categorisation.

Emissions Factors
• Emissions factors are quantities of GHGs produced per unit of emitting activity.
• The analysis is usually done by or for a government department.
• They are reviewed from time to time (annually)
Emissions factors
Greenhouse Gas Emissions Factors commonly used examples*
Natural Gas: 51.33 kg CO2-e / GJ
Electricity (Vic): 1.22 kg CO2-e / kWh
Food waste: 0.9 kg CO2-e / kg
Petrol: 2,288 kg CO2-e / kL
* from NGAF June 2009 Note that these change regularly and the latest NGA Factors workbook should be consulted
Where are emissions factors found?

Calculating emissions
To calculate the emissions due to a given activity, we must know:
1. The amount of the activity taking place.
2. The emissions factor associated with that activity.
The calculation is then:
activity x emissions factor = emissions (CO2-e)
