¶ … Sustainability classifications in engineering: discipline and approach," the author sifts through the plethora of definitions, theories, and political viewpoints in relation to the concept of sustainability. The engineering sciences play a unique role in sustainability science, and are responsible for at least participating in the discussion about sustainability. In fact, the concept and practical application of sustainability is of the utmost importance to the engineering community. However, engineering departments at universities and individual scientists do not agree on a definition of sustainability -- or on the role of the engineer.

The primary and most formidable issue in sustainable engineering is the mitigation of climate change. Whether the causes for climate change matter to the engineer is one of the issues in sustainability literature. The engineer is ultimately more concerned about solutions to climate change than about causes, which are important only insofar as it affects future trajectories. A comprehensive examination of sustainability discourse can impact the development of public policy.

One issue related to sustainability is what relative or intrinsic value is placed on nature. Another concept that arises in the discourse on sustainability is what responsibility one generation has for the next in terms of caring for the environment and preventing problems like pollution or climate change. Thus, there are ecological, economic, and social issues as well as political problems at stake. The author also points out the legal and institutional issues involved in sustainability discourse as well as the technological implications.

Sustainability is at once a theoretical and practical concept. Both abstract and concrete, sustainability has different implications depending on the field of application. Therefore, an engineer will conceive of sustainability differently from an attorney or a consumer. The author outlines the various ideological underpinnings of sustainability discourse and presents a comprehensive model for a systems approach to sustainability science. Sustainability represents the intersection between science, philosophy, economics, ethics, and politics. Therefore, sustainability must be understood as a multi-dimensional and multi-disciplinary issue.
