Carbon Accounting - learn from the National Centre for Sustainability
- 1. Carbon Green is nice, but can it make me money? Accounting
- 2. NCS Swinburne – Offering you courses in Carbon Accounting and Carbon Management > Short Course in Carbon Accounting (face to face or online) > Short Course in Carbon Farming and Trading > Diploma of Carbon Management (face to face or online) VISIT www.swinburne.edu.au/ncs
- 3. 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.
- 4. 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
- 5. GWPs of the six Kyoto gases Global Chemical Uses/ The 6 Kyoto GHGs Warming Formula Major Sources Potential* Fossil fuel combustion, Carbon dioxide CO2 1 Land use change, Cement Natural gas Methane CH4 21 Enteric fermentation Anaerobic decomposition Nitrous oxide N2 O 310 Fertilisers, Combustion Electronics, Cathodes for Perfluorocarbons C3 F 8 7,000 aluminium manufacture Hydrofluorocarbons CHF3 (HFC-23) 11,700 Refrigerant High voltage switchgear, Sulphur hexafluoride SF6 23,900 Manufacture of magnesium * For 100 year time horizon. * the typical uncertainty value is +/-35% Source: DCC NGA Factors November 2008
- 6. 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
- 7. Operational boundaries - Scopes Defines which emissions sources are included or excluded and their categorisation. Source: GHG Protocol
- 8. 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)
- 9. 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
- 10. Where are emissions factors found? Australian Government - National Greenhouse Accounts (NGA) Factors The source for almost all of your emissions factors! http://www.climatechange.gov.au
- 11. 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)

Notes de l'éditeur
- Point out that there are pathways from CA course into various other areas of sustainability.Point out new courses.DoCM is esp applicable to CA students, where they gain 2 credits out of 6 required units.These slides from beginning to now (ideally) need to be done by 9.30.
- Think back to the diagram of the Greenhouse, these different gases have different ‘global warming potentials’ – or in the example different thicknesses of glass on the greenhouse.
- The only time this is applied on the course is the calculation of refrigerant leakage . . .Measuring stickTemperatureCommon currencyMass basedWhile CO2 is the gas we hear most about, there are others mentioned under KyotoUse analogy of an R rating for insulation, or a blanket equivalent rating for a doonaMay want to note that strength is also a function of its life in the atmosphere – eg CH4 is short-lived in the atmosphere, and does most of its damage in the 1st 25 years – therefore more urgent
- Conduct some verbal calculation exercises
- WRI & WBCSDThere is another standard – ISO 14064-1/2/3.This builds on (does not compete with) the GHG ProtocolCan be certified to ISO but not to the GHG ProtocolComparison: http://www.ecologia.org/ems/ghg/news/cop9/comparison.html
- “Here are some examples of commonly used emissions factors from the NGA Factors workbook.”
- “In Australia, this is the primary resource. We’ll discover more sources on Day 2” Advise students to consider printing a copy in time for Day 2
- “Now that we know what emissions sources we have, we can start thinking about calculating the emissions. This is how we do it. Not that two main elements are involved. We’ll now discuss each of them.”
