Aspect GRI Performance Indicators are first organized by general sustainability Category (economic, environment, labor, human rights, society, product responsibility), and then further arranged under Aspect headings which more specifically reflect the issue each indicator is designed to measure. For example, Performance Indicator EN8 (water withdrawal) falls under the Water Aspect, within the Environment Category. Indicator EN11 on protected areas also falls under the Environment Category, but is found in the Biodiversity Aspect. Each Indicator Aspect may have one or more indicators categorized under it.
