Globally Recognized Indicators

• Global Reporting Initiative (GRI)*– Environmental Performance Indicators

• Core Indicators• Additional Indicators

• World Business Council for Sustainable Development (WBCSD)*– Environmental Influence Indicators

• Generally Applicable and Potential Indicators• Business-Specific Indicators

– Eco-Efficiency Profile

* GM uses the GRI guidelines for public reporting and helped develop the WBCSD indicators, which are not as extensive as those of the GRI.

GRIEnvironmental Performance Indicators

Core Indicators• Materials

– Types and weights of materials used– Percentage of post-consumer and post-industrial used

• Energy– Types and joules of energy used– Joules of purchased energy used

• Water– Total water used

• Biodiversity– Amount of land held in biodiversity-rich habitats– Major biodiversity impacts associated with activities

and/or products and services• Compliance

– Incidents of and fines for environmental non-compliance

GRIEnvironmental Performance Indicators

Core Indicators (continued)• Emissions, Effluents, and Waste

– Greenhouse gas emissions– Use and emission of ozone-depleting substances– NOx, SOx, and other significant air emissions, by type– Total amount of waste by type and destination– Significant discharges to water, by type– Number and volume of significant spills of chemicals,

oils, and fuels• Products and Services

– Significant environmental impacts of principle products and services

– Percentage by weight of products reclaimable and those actually reclaimed at the end-of-life

WBCSDEnvironmental Influence Indicators

Generally Applicable Indicators• Energy

– Types and joules of energy purchased and used– Minus energy sold to others

• Materials– Metric tons of materials used

• Water– Cubic meters of water used from all sources

• Ozone Depleting Substance (ODS) Emissions– Metric tons of CFC11 equivalents

• Greenhouse Gas (GHG) Emissions– Metric tons of CO2 equivalents

WBCSDEnvironmental Influence Indicators

Potential Generally Applicable Indicators• Acidification Emissions to Air

– Acid gases and mists emitted to air from fuel combustion, process reactions, and treatment processes

• Total Waste– Metric tons of substances destined for disposal

Business-Specific Indicators (Examples)• Priority heavy metals emissions to surface water

– Metric tons of Cu equivalents• Waste to landfill - metric tons• Waste to incineration - metric tons• Photochemical oxidant creation

– Metric tons of VOC & NOx or Ethylene equivalents• Eutrophication emissions to surface water

– Metric tons of phosphorus equivalents• Chemical oxygen demand to surface waters

– Metric tons of oxygen• Packaging - metric tons• GHG emissions from purchased electricity

– Metric tons of CO2 equivalents

WBCSDEnvironmental Influence Indicators

Recommended SP Metrics

Basic Indicators• Energy use in gigajoules• Water use in cubic meters

• Greenhouse gas emissions in CO2 equivalents

• Waste in metric tons– Recycled– Non-Recycled

Possible Data Source: Voluntary Programs• EPA WasteWise program reports• State-sponsored pollution prevention program reports
