LCA Environmental Impact Indicators

Environmental Impact Indicators are standardized metrics used in Life Cycle Assessment (LCA) to quantify the potential environmental effects of a product, process, or system. These indicators translate inventory data (inputs and emissions) into environmental relevance, supporting data-driven decision-making in sustainability, compliance, and product design.

These indicators are central to methodologies such as ISO 14040/44, Product Environmental Footprint (PEF), EN 15804, and are integrated in data exchange models like IMDE to enable modular, interoperable LCA reporting.

Purpose

Environmental impact indicators:

  • Provide a quantified understanding of sustainability performance.
  • Enable comparability across products and life cycle stages.
  • Support regulatory and corporate sustainability goals (e.g., CSRD, EU Green Deal, GHG Protocol Scope 3).

Standardized Indicators

The table below lists the most common indicators used in LCA, their unique IMDE taxonomy keys, and their formal definitions.

Indicator Name Key Definition
Climate Change Potential CFP Measures greenhouse gas emissions (e.g., CO₂, CH₄, N₂O) across the life cycle, expressed in CO₂-equivalents (GWP).
Water Use WFP Assesses total freshwater use, including direct and indirect consumption of blue, green, and grey water.
Primary Energy Demand EFP Quantifies total energy consumption (renewable and non-renewable) throughout the product life cycle.
Resource Use RCP Measures the depletion of abiotic resources such as metals, minerals, and fossil fuels.
Waste Production WGP Quantifies total waste generated, categorized as hazardous, non-hazardous, or inert.
Biodiversity Impact EQI Evaluates potential impacts on ecosystem quality, species diversity, and natural habitats.
Land Use Change LUC Assesses impacts from land occupation and transformation, including habitat destruction or degradation.
Air Emissions API Measures emissions that affect air quality, such as NOₓ, VOCs, SO₂, and particulate matter (PM).
Human & Ecotoxicity TOX Evaluates harmful effects of toxic substances on human health and ecological systems.
Acidification & Eutrophication AEI Assesses the potential for acid rain formation and nutrient enrichment in ecosystems (e.g., water bodies).
