The method consists of various parameters such as the life cycle analysis and additional pluses and minuses.
The life cycle analysis is retrieved from a database (Agribalyse) that was developed by order of the French government. The life cycle analyses in this database are performed using product category averages. We convert the value obtained from that database to a score out of 100, in line with the Eco-score methodology.
The possible additional pluses and minuses allow us to make interesting nuances at product level. We can refine that system, taking into account the reality and specificity of the Belgian market. We are looking to adjust the algorithms and are consulting with the French collective in this respect.
We thus adapt the calculation method to the Belgian reality, but at the same time, the life cycle analyses database is also periodically completed and adapted:
including progressing insight in calculating environmental impact
adjusting values for the many data points needed
deleting specific product categories and adding new ones
Such an adjustment was carried out in October 2022, which means that the Eco-score is being recalculated. Most products keep the same letter (Eco-score A to E), others are awarded another letter due to the change in the Agribalyse database. Most score better (e.g. from C to B) while a few are given a lower Eco-score (e.g. from B to C).
