CNE’s position on the comparisons of environmental impacts of packaging made from different materials.

Several economic stakeholders present comparisons of environmental impacts of packaging made from different materials.
poidsCNE considers that current comparisons which do not take all impacts into account are not acceptable. CNE is therefore proposing a methodology to make these comparisons sound and relevant for consumers, ensuring fair, objective and complete information.
The CNE recommends complying with at least three key points:

  1. Two packaging made from different materials can only be compared if the packaging deliver the same value in use to the consumer/user (same features and usage characteristics) of the packaged product.
  2. The comparison can only be made from a full multi-criteria LCA that has been critically reviewed: a comparison based on just one or two criteria is not representative of environmental impacts as a whole.
  3. A comparison in which the examined impacts do not vary significantly in the same way (beyond error margins) does not make conclusions possible.
