Environmental indicators
GRI Indicator 1 / Description of indicator	Links to information
EN1 Material use other than water, by type	Energy use Land use
EN2 Percentage of materials used that are wastes from sources external to the reporting organisation	These data are not collected at the Group level. However, we do report on recycling/reuse of waste generated at our operations. Recycling is also discussed in the context of product stewardship.
EN3 Direct energy use segmented by primary source	Sources of energy
EN4 Indirect energy use	Energy use
EN5 Total water use	Water used at our operations
EN6 Location and size of land owned, leased, or managed in biodiversity rich habitats	Currently not reported, however, we do report on land used for our activities. We are also developing a biodiversity strategy.
EN7 Description of the major impacts on biodiversity associated with activities and/or products and services in terrestrial, fresh-water, and marine environments	Currently not reported, however, we do report on land used for our activities and quality and receiving environments of water returned to the environment. We are also developing a biodiversity strategy.
EN8 Greenhouse gas emissions	Greenhouse gas emissions
EN9 Use and emissions of ozone depleting substances	Greenhouse gas emissions by type
EN10 NOx, SOx, and other significant air emissions by type	NOx emissions are not currently collected at the Group level, however, we do report on other air emissions
EN11 Total amount of waste by type and destination	Mineral and non mineral waste generation and management
EN12 Significant discharges to water by type	Water returned to the environment
EN13 Significant spills of chemicals, oils, and fuels in terms of total number and total volume	Spills
EN14 Significant environmental impacts of principal products	Product stewardship, including properties of Rio Tinto metals and minerals
EN15 Percentage of the weight of products sold that is reclaimable at the end of the products' useful life and percentage that is actually reclaimed	Currently not reported, however, through our product stewardship strategy we are working to better understand the lifecycle of our products
EN16 Incidents of and fines for non-compliance with all applicable international declarations/conventions/treaties, and national, sub national, regional and local regulations associated with environmental issues	Fines for infringement of occupational health, safety and environmental regulations
EN17 Initiatives to use renewable energy sources and to increase energy efficiency	Climate change programme Energy programmes
EN20 Water sources and related ecosystems/habitats significantly affected by water use	Currently not reported, however we do report on the quality and sources of water withdrawn from the environment and receiving environments for water returned to the environment
EN22 Total recycling and reuse of water	Water used at our operations, including recycled water
EN23 Total amount of land owned, leased, or managed for production activities or extractive uses	Land used for mining, processing and related activities
EN25 Impacts of activities on protected and sensitive areas	Currently not reported, however, we do report on our biodiversity strategy.
EN26 Changes to natural habitats resulting from activities and operations and percentage of habitat protected or restored	Types of land disturbed and rehabilitated
EN27 Objectives, programmes, and targets for protecting and restoring native ecosystems and species in degraded areas	Biodiversity strategy
EN30 Other relevant indirect greenhouse gas emissions	Other indirect greenhouse gas emissions
EN31 All production, transport, import, or export of any waste deemed hazardous under the terms of the Basel Convention (Annex I, II, III, and VIII).	Hazardous waste
EN32 Water sources and related ecosystems/habitats significantly affected by discharges of water and runoff	Currently not reported, however we do report on the receiving environments for water returned to the environment
EN33 Performance of suppliers relative to environmental components of programmes and procedures described in response to Governance Structure and Management Systems	Our reporting on managements systems covers aspects of supply chain management eg, safety, occupational health and environment
EN35 Total environmental expenditures by type	Close down, restoration and other environmental costs Expenditure on research and development Fines for infringement of environmental regulations
