It’s already the case that you have to do this for certain groups of products in France under the AGEC laws. Take for example this dishwasher: https://www.ikea.com/fr/fr/p/diskad-lave-vaisselle-encastrab... .

The data sheet listing those factors for this model is here: https://www.ikea.com/fr/fr/files/pdf/4f/fd/4ffd4fd2/indice-d...
