Quelle est l'ampleur des impacts qu'un produit peut avoir sur l'environnement? Les informations environnementales sur les produits doivent à la fois guider les consommateurs dans leur choix et favoriser une production plus respectueuse de l'environnement. Agroscope a étudié deux des méthodes les plus importantes actuellement. Conclusion: ce sont des instruments précieux, mais qui nécessitent encore des adaptations et des compléments.
«Le problème vient de la diversité des méthodes d'évaluation des performances environnementales», explique Jens Lansche, responsable de projet du groupe de recherche Analyse de cycle de vie à l'Institut des sciences en durabilité agronomique IDU d'Agroscope.
