3.1 Operation of eligible offsets projects
An eligible offsets project must be operated in accordance with this Part.

The concentration of fat in the diet of the milking herd must not exceed 70 grams of fat per kilogram of dry matter intake in any season.
Part 4 The carbon dioxide equivalent net abatement amount
Division 4.1 The carbon dioxide equivalent net abatement amount
4.1 The carbon dioxide equivalent net abatement amount
Note See paragraph 106(1)(c) of the Act.
For an eligible offsets project to which this Determination applies, the carbon dioxide equivalent net abatement amount for the project is the carbon dioxide equivalent of the amount of greenhouse gas emissions avoided as a consequence of the project, calculated using the Dietary Fats Calculator in accordance with this Part.
4.2 Carbon dioxide equivalent net abatement amount if dietary fat limit exceeded
For each milking herd, if the dietary fat limit mentioned in section 3.5 is exceeded in any season of a project year, the carbon dioxide equivalent net abatement amount for that milking herd in that project year is zero.
4.3 Calculation of the carbon dioxide equivalent net abatement amount
(1) The carbon dioxide equivalent net abatement amount for each milking herd for each project year must be calculated using the Dietary Fats Calculator by entering into the Dietary Fats Calculator:
(a) the inputs for the baseline determined in accordance with this Part; and
(b) the inputs for the project year determined in accordance with this Part.
(2) Where data from the National Inventory Report is required to carry out calculations in this Part for a baseline year or project year, the relevant data is:
(a) if the data is available in a National Inventory Report for the baseline or project year—the data published in the National Inventory Report that relates to that baseline year or the project year; or
Note Data published in a National Inventory Report relates to the period 2 years before the year of publication. For example, the National Inventory Report 2010 was published on 1 April 2012 and contains data relating to 2010.
(b) if the data is not available in a National Inventory Report for the baseline or project year—the data published in the most recent National Inventory Report.
Note The use of the most recent National Inventory Report in this circumstance will mean that the data that is used will not be data that relates specifically to that baseline or project year. For example, if the third baseline year corresponds to the 2013 calendar year, then data for the third baseline year will not be available until the National Inventory Report 2013 is published in 2015. In this case, paragraph (b) permits the use of the data reported in the most recent National Inventory Report being the National Inventory Report 2011 published on 1 April 2013—until the next National Inventory Report is published.
4.4 Greenhouse gases accounted for
The Determination takes into account methane emissions from enteric fermentation.
(1) For the purposes of paragraph 106(4)(f) of the Act, the baseline for the project must be calculated by entering each input for the baseline years mentioned in subsection (2) into the Dietary Fats Calculator.
Selecting baseline years
(2) For the purposes of subsection (1), the baseline years are 3 consecutive years:
(a) starting on the first day of a season;
(b) ending before the start of the first project year; and
(c) not starting earlier than 7 years before the start of the first project year.
Minimum baseline data
(3) There must be sufficient data available in relation to each of the baseline years to populate the Dietary Fats Calculator with seasonal data relating to:
(a) average number of milking cows in the milking herd (Nj);
(b) average milk production (MPj); and
(c) intake of feed type other than pasture (DMIf,j).
Note If the minimum baseline data for 3 consecutive years before the start of the first project year is not available, it will have to be collected before the project can start.

(2) For each season, the intake of pasture must be determined only when the inputs mentioned in sections 4.6 to 4.13 have been entered into the Dietary Fats Calculator.
(3) For each season, estimate the average daily dry matter intake of pasture of a milking cow in the milking herd using the following formula:
Equation 7 |
Where:
