Life Cycle Assessment Software (LCA)

A Life Cycle Assessment (LCA) is a structured method for evaluating potential environmental impacts associated with a product or product system throughout defined stages of its life cycle.

ISO 14040 describes the LCA framework around four central areas:

1. Goal and scope definition
2. Life Cycle Inventory (LCI) analysis
3. Life Cycle Impact Assessment (LCIA)
4. Life cycle interpretation

ISO 14044 provides requirements and guidelines covering these phases as well as reporting, critical review and limitations.

Depending on the purpose and selected system boundary, an assessment may examine raw materials, production, transportation, distribution, use, maintenance and end-of-life treatment.

The EU Product Environmental Footprint methodology also takes a life-cycle approach to measuring potential environmental impacts and emphasises reliable, consistent environmental information.

A product LCA can require information from engineering, procurement, suppliers, manufacturing sites, logistics teams and sustainability specialists. Managing this through disconnected spreadsheets can make it difficult to control versions, assumptions, data sources and product changes.

Life Cycle Assessment software provides a structured environment for organising this information and connecting individual inputs to the product system they represent.

For B2B organisations, a well-managed LCA process can support:

• Product environmental performance assessment
• Identification of environmental hotspots
• Material and design improvement studies
• Supplier and sourcing decisions
• Cradle-to-gate or cradle-to-grave assessments
• Customer environmental information requests
• Product sustainability programmes
• Product Environmental Footprint work where applicable
• Environmental Product Declaration preparation
• Environmental claim substantiation
• More structured sustainability and product data management

LCA is broader than a Product Carbon Footprint because it can evaluate multiple environmental impact categories rather than climate change alone. ComplyMarket's own guidance distinguishes LCA as the wider environmental assessment and identifies it as a useful foundation for eco-design, hotspot analysis and EPD preparation.

The ComplyMarket LCA approach follows the environmental model from product definition through calculation and reporting rather than treating the final footprint as an isolated number.

The workflow reflects the granular modelling approach described in the supplied ComplyMarket LCA manual.

Reliable environmental modelling begins with knowing what the product actually contains.

ComplyMarket's Bill of Materials structure can connect a finished product with components, materials and substances, providing a detailed product hierarchy that can serve as a foundation for sustainability analysis.

For LCA work, organisations should prepare data such as:

These data groups are directly reflected in ComplyMarket's LCA operating guidance.

A practical rule is to link supporting evidence and assumptions to the exact material, process or model line they support instead of storing explanations separately from the calculation.

Environmental impact does not stop at the material list.

The ComplyMarket workflow allows the LCA model to represent product-specific foreground processes, including manufacturing and assembly. Process-level inventory can include electricity, heat, water, fuels, chemicals, auxiliaries, scrap, wastewater, waste and direct emissions.

Transportation can then be evaluated across supplier-to-factory, inter-site and outbound distribution routes, with consideration of transport mode, distance, transported mass, load factors and relevant warehousing or distribution activities.

Where the system boundary requires it, use-phase modelling can incorporate energy or water consumption, maintenance, repairs, replacement and service travel. End-of-life modelling can address collection, dismantling, recycling, reuse, incineration and landfill scenarios while keeping recycling assumptions and potential credits methodologically consistent.

This helps organisations move from a material-only footprint toward a more complete representation of the defined product life cycle.

Once the inventory model has been completed, the appropriate Life Cycle Impact Assessment method can be applied.

ComplyMarket's workflow keeps the physical inventory database and LCIA methodology as separate modelling layers. The selected method therefore needs to be compatible with the underlying elementary flows and the purpose of the study.

Depending on the selected methodology, results can support analysis of climate impact and other environmental impact categories.

The results workflow is designed to support views such as:

• Overall environmental indicators
• Life-cycle-stage contributions
• Material and process hotspots
• Process-level results
• Geographic or location-based results
• Life Cycle Inventory details
• Data-source and provider records
• LCIA calculation information
• Uncertainty information where configured

Hotspot analysis is particularly useful for identifying where further investigation or improvement activity should focus. A high-impact material or stage should first be checked for data, unit, provider or modelling errors before it is used as the basis for redesign decisions.

An LCA result is only as reliable as the model and evidence behind it.

ComplyMarket's workflow includes validation checks covering areas such as BOM completeness, mass balance, product-flow mapping, providers, foreground processes, product-system links, method compatibility, regionalisation, uncertainty and EPD readiness. Critical modelling issues should be resolved before final calculation.

Where uncertainty analysis is appropriate, Monte Carlo calculations can be used to examine the effect of uncertain quantities, parameters and datasets. However, uncertainty ranges do not replace the need to review structural choices such as missing processes, incorrect flows or unsuitable datasets.

A useful LCA needs more than a headline number. The study should preserve the context needed to understand how the result was produced.

Relevant outputs can include the goal and scope, reference unit, boundary, inventory sources, methodology, assumptions, environmental results, hotspots, data quality, uncertainty, limitations and calculation records. ComplyMarket's LCA documentation also describes LCA reports, structured exports and reproducible model records for supporting review and traceability.

The workflow can also support EPD preparation and readiness. However, an EPD draft is not automatically a published or verified EPD. Applicable Product Category Rules, programme requirements and the required independent verification or registration route still need to be completed.

For a more dependable and reusable LCA process:

1- Define the purpose before collecting data. The business question determines the required boundary, evidence and methodology.

2- Use a clear functional or declared unit. All results need a consistent reference quantity.

3- Build from the actual product BOM. Reconcile material quantities against product mass and investigate unexplained differences.

4- Prioritise primary data where appropriate. Use relevant site and supplier information when it is available and sufficiently reliable.

5- Document assumptions and exclusions. Avoid hidden modelling decisions.

6- Maintain consistent units. Unit conversion errors can materially distort results.

7- Keep product versions traceable. Material, supplier, facility or design changes can affect the validity of an existing assessment.

8- Validate hotspots before acting on them. Check whether unusually high results come from the real product system or from a modelling problem.

9- Keep methodology and evidence together. Preserve sources, assumptions and calculation records for future review.

10- Update the assessment when important inputs change. LCA should be treated as a managed product-data process rather than a one-time spreadsheet exercise.

ComplyMarket can help organisations connect LCA activities with the wider product, supplier and sustainability data environment.

The platform already structures product information across finished products, components, materials and substances and connects that information with supplier and documentation workflows. Its sustainability reporting environment also includes Life Cycle Assessment reporting for BOM items. The existing ComplyMarket user manual describes LCA views containing GHG, energy, water and study-document information for individual BOM items.

Through the wider LCA workflow, ComplyMarket can support organisations in structuring:

• Product and BOM data for LCA modelling
• Supplier and facility information
• Material and recycled-content information
• Manufacturing inputs and process inventories
• Logistics, use-phase and end-of-life scenarios
• Product-flow, activity and provider relationships
• LCIA configuration and environmental result analysis
• Data-quality and uncertainty information
• Model validation and traceability
• Environmental hotspot identification
• LCA reporting and structured exports
• EPD preparation and readiness workflows

This connected approach is consistent with ComplyMarket's broader product-data strategy of bringing product, supplier, compliance and sustainability information into one structured environment rather than managing each requirement in isolation.
