By Glenn Hasek The World Business Council for Sustainable Development (WBCSD) has released a report entitled, "Eco-efficiency: A Guide to Reporting Company Performance." The report provides a common environmental measurement framework that can be adopted by companies of any size. It includes a common set of definitions, principles, and indicators flexible enough to be widely used and interpreted across all industries. The report defines two indicator categories: "generally applicable indicators," valid for virtually all businesses; and "business specific indicators," intended to fit the particular context of individual companies. These indicators, says WBCSD, "provide a strategic tool for business managers, enabling them to assess, measure, and increase eco-efficiency performance and improve decision-making."
