Environmental information and consumer choices
Price, quality, brand and availability are among the factors that most strongly influence purchasing decisions, particularly for frequently purchased products. Even so, information about environmental performance can play an important role in certain circumstances.
During the development of the European Product Environmental Footprint (PEF) method, the European Commission examined how consumers responded to different ways of communicating environmental footprint information. The work explored both the situations in which environmental information influences choice and the characteristics that make it more understandable and useful.
When environmental information can carry more weight
The findings reported at the time identified several situations in which environmental performance may become more relevant: when products have similar prices; when the purchase is significant, expensive and long-lasting, such as a car; and when products may affect the health of consumers or their families.
Communication also matters. Information needs to be clear, comparable and credible, and appropriate to the product and audience. A score or label without context can be difficult to interpret; an oversimplified message can hide important differences between impact categories.
The role of LCA and the limits of communication
Life Cycle Assessment (LCA) can examine environmental impacts across a value chain. In the European context, the PEF methods seek to harmonise this assessment through common rules and impact categories, including specific rules for certain product groups.
A robust assessment does not automatically result in effective communication. The scope, assumptions and limitations of the information presented need to be explained. Nor should a single indicator be assumed to represent every relevant environmental aspect.
Environmental information can support more informed choices, but it works best when it is transparent, verifiable and considered alongside other product attributes. Responsibility for improving environmental performance is shared by businesses, consumers and public authorities.
