Environmental indicators

GRI - Environmental indicators

GRI Indicator	Description of indicator	Links to information
EN1	Weight of materials used by weight or volume.	Supply chain Energy use Water inputs Land access
EN2	Percentage of materials used that are recycled input materials.	We expect to increase our use of material derived from wastes external to the organisation. Currently the percentage of this material is negligible compared to the total amount of materials used by Rio Tinto. Recycling Water balance Water inputs
EN3	Direct energy consumption by primary energy source.	Energy use
EN4	Indirect energy consumption broken down by primary source.	Energy use
EN8	Total water withdrawal by source	Water Water inputs
EN11	Location, and size of land owned, leased, managed in, or adjacent to, protected areas as well as areas of high biodiversity value outside protected areas.	Biodiversity Biodiversity maps Biodiversity strategy
EN12	Description of significant impacts of activities, products, and services on biodiversity in protected areas and areas of high biodiversity value outside protected areas.	Biodiversity Biodiversity maps Biodiversity Strategy Case Study: Measuring our effect on biodiversity (2006 SD Review, page 18)
EN16	Total direct, and indirect greenhouse gas emissions by weight.	Climate change and energy Climate change position Greenhouse gas emissions
EN17	Other relevant indirect greenhouse gas emissions by weight.	Climate change and energy Climate change position Greenhouse gas emissions
EN19	Emissions of ozone-depleting substances by weight.	We have been eliminating the use of ozone depleting substances for many years in line with local legislation and environmentally good practice. Materiality assessment shows this topic is not sufficiently important to our stakeholders to warrant inclusion in our reporting.
EN20	NOx, SOx, and other significant air emissions by type, and weight.	Air quality SOx Fluoride Dust
EN21	Total water discharge by quality, and destination.	Water Water output
EN22	Total weight of waste by type, and disposal method	Waste Waste rock Tailings Acid Rock Drainage Non Mineral Waste Recycling
EN23	Total number, and volume of significant spills	Goals and targets Environmental management
EN26	Initiatives to mitigate the environmental impacts of products and services, and extent of impact mitigation.	Product Stewardship Product Stewardship Engagement
EN27	Percentage of products sold and their packaging materials that are reclaimed by product category.	Rio Tinto's major products are mined metals and minerals, which are sold in bulk rather than in packages (exceptions include borates and talc). Packaging materials are not generally recycled, but products shipped in packages constitute less than 5% of Rio Tinto's business. There were no product recalls. Gold, silver, platinum and palladium are recycled at rates greater than 70% because of their high value. Aluminium, copper, iron, titanium and zinc all have a recycle rate that ranges form 40-50%. Coal is not recycled as it is consumed. Borates, talc and zircon are not recycled due to the low value of the mineral at the end of life.
EN28	Monetary value of significant fines and total number of non-monetary sanctions for non-compliance with environmental laws and regulations.	Our perfomance Environmental management
MM3	The number/percentage of sites identified as requiring biodiversity management plans and the number/percentage of sites with plans in place. Also include criteria for deciding that a biodiversity management plan is required and the key components of a plan.	Biodiversity Biodiversity maps Biodiversity strategy Case Study: Measuring our effect on biodiversity
MM4	Percentage of products derived from secondary materials.	Improving Performance Together Water Water inputs
MM5	Describe policies for assessing the eco-efficiency and sustainability attributes of products.	Product Stewardship Environmental Management
MM6	Describe approach to management of overburden, rock, tailings and sludge's/residues.	Waste Waste Rock Tailings Acid Rock Drainage Environmental management
