Accounting policies (continued)
Emissions from whey relates to externally purchased whey
for the largest sites of Arla Foods Ingredients. Included
whey is standardised and recalculated based on the milk
solid content to consider the difference in quality and
fractions purchased at Arla. The emission factor related to
externally purchased whey was unchanged at 1.0, a
conservative estimate (Flysjö, 2012).
Arla collects data from transport and packaging suppliers
covering a minimum of 95 per cent of the spend, and
based on the collected data, emissions are scaled up to
cover 100 per cent. Biogenic emissions are not currently
disclosed in the ESG section but will be disclosed from
2022. For transport, operations and packaging emission
factors are obtained from Sphera, an industry-leading
consultancy firm. The emission factors are updated
annually to the most recent complete data set for the
same year, in this case 2017. Emission factors are
unchanged compared to 2020 due to changes in delivery
time from Sphera. Farm-level emission factors are obtained
from 2.-0 LCA Consultants. For non-owner milk, emission
factors were unchanged at 2015 levels.
Scope 3-Emissions on farm
Scope 3 emissions from raw milk are calculated in
accordance with the International Dairy Federation's
guideline for the carbon footprint of dairy products (IDF
2015). The tool used for calculating the carbon footprint
from milk is based on an attributional life-cycle assessment
(LCA) that has been developed during the last decade in
collaboration with 2.-0 LCA Consultants, a Danish
consultancy firm formed by academics. For detailed
descriptions of methodology, please refer to Schmidt and
Dalgaard (2021). Farm-level emission factors are also
obtained from 2.-0 LCA Consultants. Non-owner milk
emissions are calculated by multiplying milk volume with
emission factors based on national inventory data and not
Arla specific data. The calculations are based on an earlier
version of the farm tool following IDF 2010 (Dalgaard R,
Schmidt J, Cenian K, 2016).
Emissions related to raw milk include emissions both on
and off farm. The emissions relate to the cow's digestion,
feed production and purchase, manure storage, energy
usage, capital goods and peat soils. Emissions related to
feed include fertilizer for home-grown feed and purchased
feed, and transport of purchased feed. Manure storage can
result in methane and nitrous oxide emissions. The
amount of emissions varies depending on how manure is
covered and whether it is used for biogas production. Peat
soils are wetland with a high CO2e content. When soils are
drained and used in crop production CO2 and N2O are
released. The emission figure related to raw milk presented
in this report is a weighed average emission per kg of milk,
calculated based on validated climate data from farms
where the data has been validated by external climate
experts, multiplied by the fat and protein adjusted milk
intake. Farms visited by external climate experts are
statistically representative of all Arla farms.
Uncertainties and estimates
In 2021,93 per cent of Arla's active farmer owners,
covering 98 per cent of Arla's owner milk volume,
submitted a detailed Climate Check questionnaire (farmers
receive an incentive of 1.0 EUR-cent/kg of milk to
complete the survey). Their answers were validated by
external climate experts. This report includes only
externally validated data which at year end 2021,
accounted for 77 per cent of Arla's active farmers.
Farmer owners complete the Climate Check once a year
based on data from their most recent financial year. This
could vary from farm to farm, as some have financial years
running from January to December, while others run from
July to June. Therefore, the figures presented are not
necessarily based on farm data covering the same period.
The majority of data, 61 per cent, relates to the period
1 January 2020 to 31 December 2020 while 14 per cent
relates to earlier periods.
An uncertainty analysis has been carried out to understand
the biggest areas of uncertainty related to self-reported
farm emission data. The analysis was centred around four
key levers; herd, feed, crops and manure handling, and
addressed the parameters with the highest impact on the
emissions on farm. The analysis concluded that data could
be manipulated, in worst case up to 10-12 per cent, but
only if the farmer had a starting point of high emissions
and claimed to change from no biogas treatment to full
biogas treatment of slurry. Smaller farmers and farmers
using extensive grazing systems are not always measuring
the amount of feed that the cows eat or the dry matter
content of the grass on the fields. To enable these farmers
to report, the system contains a model which calculates
feed consumption based on herd size and milk yield.
Reporting on peat soils is a developing field and still
subject to higher uncertainty than other areas. Due to
it's relatively high climate impact uncertainties related
to peat soils could have significant impact on the total
reported greenhouse gas figure. The risk of errors and data
manipulation is minimised by external climate advisors
validating the data, and also by a systematic statistical
process conducted by Arla to filter outliers. All outliers
are flagged to the climate advisors, who may go back to
the farmer to investigate. Numbers are only released for
reporting after thorough investigation.
The methodology used to calculate emissions on farm is
developing over time. Currently, factors that potentially
lower total net emissions, such as carbon sequestration on
farm and direct land use change, are not included. IDF
2015 suggest that direct land use change should be
included in the calculations.
Other uncertainty relates to data collection regarding
packaging and transport from our suppliers. Each year, Arla
sends its suppliers detailed requests to provide the
necessary data, accompanied by a manual on how to
complete the related documentation. Manual data entries
from different sources are clear risks to data quality. To
minimise the risk of reporting errors, a rigorous two-step
internal validation process is in place.
