Life Cycle Assessment (LCA)
Measure Environmental Impacts Across the Full Product Life Cycle
Life Cycle Assessment (LCA) is a structured method for evaluating the potential environmental impacts of a product, process, or system across its life cycle. Depending on scope, an LCA can examine raw-material extraction, manufacturing, transport, packaging, product use, recycling, and end-of-life treatment.
ISO 14040 defines the principles and framework for LCA, while ISO 14044 provides detailed requirements and guidance. Together, they establish four phases: goal and scope definition, life cycle inventory analysis, life cycle impact assessment, and interpretation.
Why Life Cycle Assessment Matters
For manufacturers and other B2B organizations, environmental impacts often extend beyond direct operations. Products may depend on complex supply chains, materials, production sites, energy sources, logistics routes, and end-of-life scenarios.
LCA helps organizations identify environmental hotspots and improvement opportunities. It can support product and material comparisons, eco-design, procurement decisions, resource efficiency, sustainability reporting, and stakeholder information.
LCA is not automatically proof of regulatory compliance. The methodology, system boundary, data quality, and reporting approach should match the purpose of the assessment and applicable legal, industry, or customer requirements.
The Four Main Phases of LCA
1. Goal and Scope Definition
Define the purpose, functional unit, system boundary, assumptions, and intended use.
2. Life Cycle Inventory (LCI)
Collect relevant inputs and outputs, including materials, energy, transport, emissions, waste, and supplier information.
3. Life Cycle Impact Assessment (LCIA)
Translate inventory flows into potential environmental impact categories, which may include climate change, resource use, acidification, eutrophication, and water-related impacts.
4. Interpretation
Review results, identify significant contributors, evaluate limitations, and develop conclusions consistent with the goal and scope.
Practical Guidelines for Reliable LCA
Start with a clear business objective. Define the functional unit and system boundary carefully, build a structured inventory, and prioritize reliable primary data for processes or suppliers that strongly influence results.
Document assumptions, exclusions, allocation rules, and data sources so the assessment remains transparent. Where important data is uncertain, sensitivity analysis can help determine whether assumptions affect overall conclusions.
LCA information should be reviewed when suppliers, materials, manufacturing processes, logistics routes, energy sources, or end-of-life assumptions change.
ISO Standards and EU Environmental Footprint
ISO 14040 and ISO 14044 provide the international framework for Life Cycle Assessment. EU-facing organizations may also encounter the Product Environmental Footprint (PEF) and Organisation Environmental Footprint (OEF) methods. These approaches should not automatically be treated as replacements for methodologies required by legislation or sector-specific rules.
How ComplyMarket Can Support Life Cycle Assessment
ComplyMarket can help businesses build a structured data foundation for LCA by connecting product, material, supplier, sustainability, and compliance information.
Its platform can support product hierarchies, Bills of Materials, material and substance information, supplier questionnaires, supporting documentation, and environmental data used in LCA-related workflows.
This can help companies organize product and material data, connect components with suppliers, collect sustainability information, monitor missing information, maintain evidence, improve traceability, and support repeatable environmental reporting.
By centralizing relevant product and supply-chain information, ComplyMarket can help reduce dependence on fragmented spreadsheets and manual data collection while creating a scalable foundation for Life Cycle Assessment and environmental decision-making.
