This document discusses how to distinguish between legitimate eco-labels ("green") and misleading eco-labels ("greenwash"). It explains that eco-labels are seals of approval given by governments, non-profits or independent third parties when a product meets certain environmental standards. While there are over 400 eco-labels, regulation is minimal. Legitimate eco-labels tend to be from governments or non-governmental organizations (NGOs), apply to entire companies or specific products, and involve transparency, independent verification and public standards. The document encourages consumers to consider which eco-labels have these attributes when determining which labeled products to purchase.
