Eco-responsibility started out as a trend, a commitment by a few “mission” brands before its time, and a marketing argument aimed at consumers who were more sensitive to the state of the planet. Then, it became an increasingly obligatory passage, a sort of must-have to seduce a more conscious clientele to be in the air of time. Today, the reality is quite different: it is an obligation. The various bills, at national, European and global levels, have radically changed the situation: cosmetic companies no longer have any other choice but to commit to their ecological transition. The deadlines are short and the challenges are numerous and ambitious. This dossier has been designed as a tool for professionals in the beauty sector. It reviews all the new environmental rules (obligations to respect, allegations to avoid, certifications to look for, examples to follow…) that concern the beauty sector and highlights the solutions that can and/or must be put in place.
