3. Over the last several years, NAE has, via its program on Technology and Environment, explored technology's impact on the environment through its role in production and consumption. Recent efforts in this area have focused on technology transfer (Cross-Border Technology Transfer to Eliminate Ozone-Depleting Substances, 1992); the effect of science and environmental regulation on technological innovation (Keeping Pace with Science and Engineering: Case Studies in Environmental Regulation, 1993); industrial ecology and design for the environment (The Greening of Industrial Ecosystems, 1994); corporate environmental practices (Corporate Environmental Practices: Climbing the Learning Curve, 1994); the United States' and Japan's interest in industrial ecology (Industrial Ecology: U.S./Japan Perspectives, 1994); linkages between natural ecosystem conditions and engineering (Engineering Within Ecological Constraints, 1996); design and management of production and consumption systems for environmental quality (The Industrial Green Game: Implications for Environmental Design and Management, 1997); an examination of industrial performance measures and their relation to ecosystem conditions (Measures of Environmental Performance and Ecosystem Condition, forthcoming 1998); the diffusion patterns of environmentally critical technologies and their effect on the changing habitability of the planet (Technological Trajectories and the Human Environment, 1997); the impact of services industries on the environment (exploratory workshops held in October 1994 and June 1995); the impact of polymers on the environment (exploratory workshop held in September 1996); and the role of information and knowledge management in improving environmental efficiencies (workshop held in July 1997).
