Indicator 2.10.1

Tracking use of energy inputs is a necessary step in calculating the GHG emissions associated with aquaculture production and products.

Energy inputs include all those sources of energy used for the purpose of production, including electricity and energy carriers such as diesel or natural gas.

To the extent possible, Certificate Holders are encouraged to calculate energy use specific to the certified site. However, in some cases, this may be difficult to do. For example, fuel purchased may be used to supply vessels servicing many sites, potentially both certified and non-certified sites or even multiple sites or companies.

In these cases, a portion of the overall input may be allocated to the certified site based on a logical allocation basis.

For example, dividing energy inputs between sites based on the relative number of vessel trips or using the site’s relative share of production among the group of sites serviced.

Energy inputs to hatcheries are not included in calculations of on-site energy use. However, in cases where the juvenile stage of the supply chain is integrated with grow-out, sites may choose to include this stage in their calculations to simplify calculations.

Documentation of energy intensity factors (e.g., MJ of energy per L of diesel) used if they are different to the default values used in the ASC Farm Standard Energy Use Data Submission Template.

Evidence to support the quantity of each energy input specified in calculations is available on request, along with any allocation of energy inputs between multiple sites if applicable.

This may be, for example, fuel purchase invoices or electricity use records.

The energy use value is calculated and reported in MJ of energy per tonne of live weight production.

Energy use of production is calculated for either (a) the most recent completed production cycle; or (b) three consecutive years of production.

Documentation is provided to support input variables and calculations.

The ASC Farm Standard Energy Use Data Submission Template is used to demonstrate results.

Certificate Holders are encouraged to use the ASC Farm Standard Energy Use Data Submission Template for calculating the energy intensity of production after energy inputs are quantified.

Additional energy intensity factors for a range of energy inputs are available from the UK Department of Energy Security and Net Zero.
