ENVIRONMENTAL COMMUNICATIONS WITH LCA INFORMATION: AN EXPLORATORY STUDY WITHIN THE BUILDING INDUSTRY Sergio A. Molina –Murillo Timothy M.

Environmental Messages are difficult to communicate • Environmental issues are themselves complex and require significant disclosures in light of many information asymmetries. • The legitimacy of multiple stakeholders, each one providing often conflicting expert information to an already crowed media marketplace. • Consumers and buyers function within a skeptical ‐ mode when exposed to environmental messages.

British supermarket chain Tesco, would spend almost $1 billion over the next five years to lead "a revolution in green consumption” (New York Times, March 6 th , 2007). “ To create a mass movement in green consumption we must provide better information” ( Sir Terry Leahy, Tesco CEO 01/18/2007)
Environmentally Preferable Products • The end-consumer market size of sustainable products is over $200 billion in the U.S. (LOHAS 2005) • The U.S. Federal Government procures $200 billion annually and several executives’ orders encourage to give preference to “green” products. • Wal ‐ Mart’s recent announcement to aggressively encourage its 60,000 suppliers to create products that don't harm the environment (Hudson 2007).
Product: bundle of benefits Environmental communications are often considered in isolation and not Environmental communications are often considered in isolation and not in conjunction with functional product attributes/benefits. in conjunction with functional product attributes/benefits. Functional benefits: “ ingredients necessary for performing the product function as viewed by consumers ” (Keller 1993)
Research Question Does environmental information (non-functional) complement or impair functional product performance information?
Information processing & persuasion • Dual ‐ Process Models of Persuasion: (Petty and Cacciopo 1981,1984; Petty, Cacciopo and Schumman 1983; Chaiken 1980, 1994). 2 Routes of Persuasion • Central route: people examine most of the information presented to uncover the reasons in support of the proposal. • Peripheral route provides a quick accept or reject decision without deep consideration of the information content.
Conceptual Model
Methods Architects � Insulation Sample and product: Web ‐ based survey, architects randomly assigned to a single ad. • Dependent Variables: AAd, ABrand, ACompany, Purchase Intention, Credibility, Complexity • Independent Variables: Type of message (Functional/ Non ‐ functional) Explicit claim (Yes/No); Private disclosure (FUN, FIN, HEA) • Control Variables : Gender, Familiarity with product category, Environmental Concern, Ad message Involvement, Attitude towards Advertising, Familiarity with Energy Star program, Years of professional experience. • 8 Different Ads • Response rate= 21.5% (1,346); median = 10 minutes. • Included in analysis responses between 5 ‐ 20 minutes only respondents with English as the first language = 1,062). • No response bias.
