There are more than 400 “eco-labels” on the market. This confuses consumers. Because of this confusion, consumers may lose trust in these labels. Which label is better? What does this label mean? Rede ACV's Labeling working group, coordinated by Felipe Coelho, from Fundação Vanzolini, conducted a training session in partnership with GS1 on 03.18.2021. With 20 participants from various sectors (food, packaging, paper, electronics, among others), the class reflected an important ambition of Rede ACV: to promote diversity of expectations, experiences and concrete applications of life cycle thinking and LCA, debating the label's role of communicating attributes and guiding decision-making and consumption habits, always mindful of each individual's role in staying informed and being critical.
