Meaning is conveyed in words. The green movement needs to clarify its semantics—its words—if it is to lead us to sustainability. To start, the words “green” and “sustainability” mean different things, but often are used interchangeably. With sustainability being more complex in meaning and difficult to attain, we’re green washing a green Pull quote Sustainability is the destination building when calling and green is the drive there. it sustainable, unless Calling a milestone the destinait truly is. But how are tion prematurely ends the trip. green and sustainability different? Sustainability scientist and professor, James A. Wise, Ph.D., said, “Sustainability is a topdown framework of overarching principles that consider environmental, economic, and social measures based on an idealized model of what is sustainable. Green is a bottom-up approach, working to improve the environmental performance of a product or system sequentially over time. It typically is constrained to focus on environmental performance measures.” Metaphorically speaking, sustainability is the destination and green is the drive to get us there. Calling a milestone the destination prematurely ends the trip, and it could detract About the author. change Michael Ivanovich became others by changing the names on their map or mugshot. the chief editor of Consultingunwittingly shortening their trips.

The USGBC’s family of LEED rating systems are green frameworks for buildings, just as Wise described. Why the confusion of green versus sustainability? Perhaps people exchange green with sustainability to avoid repetitiveness. The word green can be formed as a noun, verb, adverb, and adjective. Hence, you can greenly green a green building to make it greener, and greening it more can make it the greenest around, but that doesn’t ensure its greenness has achieved sustainability. Substitutes for green are not as common as one would think. Eco-friendly and environmentally sensitive work well, but are longer and quickly become tiresome to readers. Joining green with other words for branding purposes or to take a shortcut to catch the eye of an audience is burdening the semantics, too. Common constructs are “green, eco-friendly buildings,” “green, high-performance buildings,” and “green, intelligent buildings.” These phrases are redundant, and detract from the integrating nature of greening. Can a green building lack good controls or not perform well and still be green? Another semantic burr is the claim that for a building to be touted as green, it has to be LEED-certified. Not true. There are multiple rating systems, and new ones may emerge. And some prefer no rating system at all. Any certification is a convenient way to communicate a level of greenness, but a long-hand way of doing so doesn’t change the facts about the building’s design, construction, or performance. And speaking of performance, will the real benchmark please stand up?
