On December 14th, 2022 the Federal Trade Commission (FTC) announced it is beginning its statutory review of the Green Guides, a set of guidelines that help marketers understand green and eco-friendly advertising claims and terminology. Initially introduced in 1992, these guides have not been revised since 2012 even while the environment for these kinds of claims has multiplied exponentially. Covering terminology such as “recycled”, “carbon neutral”, and others, the Green Guides provide essential information relevant to businesses marketing products in a world focused on sustainability. Additionally, the Green Guides apply across industries, which means answering these questions and providing data and evidence is paramount to ensure the jewelry industry is well-represented in the revisions. The opening set of questions from the FTC indicates that it is focused on a very broad review of the existing guides, but also asks for specific guidance on “recycled” and “sustainable” terminology.
