Eco labelling is a process of standardizing a product as “Green” or” Eco-friendly”. Certification determines whether a given product meets those standards. Marketing develops consumer awareness of and trust in the claim. Marketing may of course also be done by the producer of the product that is eco-labelled, but the ecolabelling organization must also market the label to consumers so that they will demand to see it on the products they buy. The effectiveness of ecolabels depends on consumer awareness of the label, and consumer acceptance of the label.
