Core indicators Additional indicators Materials EN1. Total materials use other than water, by type. Provide definitions used for types of materials. Report in tonnes, kilograms, or volume EN2. Percentage of materials used that are wastes (processed or unprocessed) from sources external to the reporting organisation. Refers to both post-consumer recycled material and waste from industrial sources. Report in tonnes, kilograms, or volume Energy EN3. Direct energy use segmented by primary source. Report on all energy sources used by the reporting organisation for its own operations as well as for the production and delivery of energy products (e.g., electricity or heat) to other organisations. Report in joules EN17. Initiatives to use renewable energy sources and to increase energy efficiency. EN4. Indirect energy use. Report on all energy used to produce and deliver energy products purchased by the reporting organisation (e.g., electricity or heat). Report in joules EN18. Energy consumption footprint (i.e., annualised lifetime energy requirements) of major products. Report in joules EN19. Other indirect (upstream/downstream) energy use and implications, such as organisational travel, product lifecycle management, and use of energy-intensive materials Water EN5. Total water use.   EN20.Water sources and related ecosystems/habitats significantly affected by use of water. Include Ramsar-listed wetlands and the overall contribution to resulting environmental trends. EN21. Annual withdrawals of ground and surface water as a percent of annual renewable quantity of water available from the sources. Breakdown by region. EN22. Total recycling and reuse of water. Include wastewater and other used water (e.g., cooling water) Biodiversity EN6. Location and size of land owned, leased, or managed in biodiversity-rich habitats. Further guidance on biodiversity-rich habitats may be found at www.globalreporting.org (forthcoming) EN23. Total amount of land owned, leased, or managed for production activities or extractive use EN7. Description of the major impacts on biodiversity associated with activities and/or products and services in terrestrial, freshwater, and marine environments EN24. Amount of impermeable surface as a percentage of land purchased or leased EN25. Impacts of activities and operations on protected and sensitive areas. (e.g., IUCN protected area categories 1–4, world heritage sites, and biosphere reserves) EN26. Changes to natural habitats resulting from activities and operations
