Comparing one kilogram of two materials can miss differences in profile geometry and the quantity needed for the project.\n\nResearch comparing wood-flour and pellet feedstocks illustrates that material preparation and transportation belong in the assessment.

Calculate the route used rather than assuming that every European-made product has a lower total footprint than every imported product.\n\nFor European procurement, request production-location and transport data alongside the resin, fibre and manufacturing information.
