This Schedule provides for the calculation of the change is emissions in a reporting period from the average annual baseline emissions, known as View image in the official source.
It does this by first calculating the annual average emissions in the baseline period and comparing that to emissions in the reporting period.
NGA Factors document means the document entitled “National Greenhouse Accounts Factors”, published by the Department and as in force from time to time.
3 Application of Schedule to CEAs and emissions accounting areas in a project area
The emissions calculated for a project area under this Schedule relate to all the CEAs and emissions accounting areas for the project area as at the end of the reporting period.
Note: Any emissions which relate to an exclusion area within a project area are not relevant to this Schedule. If the project area is varied between reporting periods, average annual baseline emissions will need to be recalculated for the new project area.
