Chapter 5 begins with a vignette about a corporate executive tasked with turning round her firm’s sustainability reputation. She must develop a holistic strategy for communicating the company’s environmental goals, progress, and achievements to its diverse stakeholders. It introduces and provides examples of the different forms, interfaces, and architectures by which corporations, government agencies, non-profit organizations and individuals can use to effectively deliver environmental information to their intended audiences. Possible delivery mechanisms include labels on products, ratings in a press release, data on a website, awards on a billboard, or slogans on a boycott sign. Concepts such as prominence, intelligibility, and feasibility are introduced and used to evaluate these different communication strategies. The chapter concludes with a further discussion of the noteworthy communication practices being used by existing information-based environmental governance initiatives.
