Abstract: | Energy and environment are complementary goals of industrial society. The OECD COMPASS project recognises the need for comprehensive information and assessment of the environmental implications of energy strategies and systems, not just energy sources, for effective policymaking in both energy and environmental fields. Energy systems are viewed from the end-use perspective in comparing the environmental effects of different trends and strategies in energy use. This paper discusses methodological criteria for effective assesstment in the environmental field, and some applications to the environmental implications of energy use in space heating and cooling, involving three case studies in different OECD countries. Some conclusions are drawn concerning energy-environment policy, in particular concerning the role of comparative assessment techniques in policymaking. |
