The LCA model was developed by external consultants and verified by independent third parties. The model assesses climate impacts throughout our value chain – from production at our farmers until the end products reach the supermarkets – and the complexity and level of detail is quite unique compared to other official LCA tools. The new model enables us to calculate the carbon footprint per kilogram meat and make specific calculations for selected products using data from specific suppliers, abattoirs, processing plants and logistics.

Two different methods

There are two different LCA methods: Attributional LCA (A-LCA) and Consequential LCA (C-LCA), where the key differences relate to the handling of by-products and data input. The different methodologies result in different system boundaries. For example, indirect land use is only included in C-LCA, while both methods incorporate direct land use. In order to create as much transparency and flexibility as possible, we have built in a switch in our new model that allows us to calculate the climate impact from our products using both methods.

Harmonised solution at EU level

We believe there is a need for a harmonised solution at EU level and therefore support the widely recognised European method for life cycle assessments called Product Environmental Footprint (PEF). This will increase transparency in LCA calculations for consumers and facilitate the use of climate data across national borders and products.The PEF method build on A-LCA, but together with interest groups we are working to also include indirect land use and other key parameters.

A-LCA (PEF)

- Average input data
- By-product modelling based on normative allocation rules
- dLUC
- Ecoinvent

C-LCA

- Marginal input data
- By-product modelling using system extension
- dLUC and iLUC
- Exiobase

Data and framework for climate calculations

The figure shows the extent of the data we use for LCA calculations. Based on the Climate Track, which is part of our sustainability programme, we collect data to calculate the climate impact of each individual farm that supplies slaughter animals (see page 20). Such a level of detail has not been possible in previous calculations, which were based on generic data.
