Creating an EPD: Environmental Indicators

Four categories of environmental indicators and their collective 24 sub-divisions are used in creating an EPD using EN 15804.

Main Indicators
Sub-division Indicators
Environmental Impact
  • Global warming potential
  • Ozone depletion potential
  • Acidification potential
  • Eutrophication1 potential
  • Formation potential of tropospheric ozone
  • Abiotic depletion potential for non fossil  resources
  • Abiotic depletion potential for fossil resources
 Resource Use
  • Use of renewable primary energy excluding renewable primary energy resources used as raw materials
  • Use of renewable primary energy resources used as raw materials
  • Total use of renewable primary energy resources (primary energy and primary energy resources used as raw materials)
  • Use of non renewable primary energy excluding non renewable primary energy resources used as raw materials
  • Use of non renewable primary energy resources used as raw materials
  • Total use of non renewable primary energy resources (primary energy and primary energy resources used as raw materials)
  • Use of secondary material
  • Use of renewable secondary fuels
  • Use of non renewable secondary fuels
  • Use of net fresh water
 Waste Category
  • Hazardous waste disposed
  • Non hazardous waste disposed
  • Radioactive waste disposed
 Output Flow
  • Components for re-use
  • Materials for recycling
  • Materials for energy recovery
  • Exported energy
Note:1 The over-enrichment of water courses e.g. increase in the concentration of nitrates and phosphates. These encourage the excessive growth of algae and reduce the oxygen content within the water causing damage to ecosystems.
