=== Bonus or malus? ===

Why is the score defined as a bonus? The lifecycle analysis of a product is based on the logistics impact of transport in France. A bonus would be logic if a product is sourced even more locally, i.e. in the geographic neighbourhood of the purchase location. If you use a product produced outside France it should imply a malus.

Thus a bonus of 0, should imply no distance larger than the mean distance, a larger distance would imply a malus and less distance a bonus.
