Many countries have introduced comprehensive environmental protection laws during the last few decades in response to the direct, visible environmental impacts of industrial activities. This has often resulted in specific technical regulations, but it has gradually been recognized that a change of awareness and management principles is needed too. In consequence, environmental management techniques have been developed to assist companies to reduce, evaluate, monitor and control their environmental impact at a corporate level. But how has this development been adopted in industry, and has it resulted in any changes in attitude? This article examines these questions, based on a survey of Danish industrial companies.
