Life Cycle Assessment
Understand Environmental Impacts Across the Complete Life Cycle of a Product or Service
Knowledge Kraft helps organizations evaluate environmental impacts beyond their own facility by examining raw materials, production, transportation, use and end-of-life stages.
Life Cycle Assessment supports better product, process, sourcing and sustainability decisions by identifying where significant impacts occur.

What Is Life Cycle Assessment?
Life Cycle Assessment is a structured method for evaluating environmental inputs, outputs and potential impacts across the life cycle of a product, service or process.
ISO 14040 defines the principles and framework for LCA, including:
- Goal and scope definition
- Life cycle inventory analysis
- Life cycle impact assessment
- Life cycle interpretation
- Reporting and critical review
The standard also addresses limitations, relationships between phases and conditions for the use of value choices.
Cradle to Gate – From raw-material extraction through production until the product leaves the facility.
Cradle to Grave – From raw materials through production, use and final disposal.
Cradle to Cradle – Includes pathways through which products or materials return to useful cycles.
Gate to Gate – Covers a selected process or manufacturing stage.
An LCA requires a clearly defined functional unit so inputs, outputs and alternatives are compared consistently.
Interpretation boundary: LCA results depend on boundaries, data quality, assumptions and impact-assessment methods. They should not be interpreted as absolute proof that one product is environmentally superior in every respect.
Challenges We Help Customers Address
- The purpose of the LCA is not clearly defined
- System boundaries are selected inconsistently
- Functional units do not support fair comparison
- Supplier data is unavailable
- Process data is not separated by product
- Secondary databases are used without suitability review
- Allocation decisions are undocumented
- Transport and end-of-life assumptions are weak
- Data gaps are hidden
- Product comparisons use different boundaries
- Results are reduced to a single impact category
- Uncertainty and sensitivity are not evaluated
- Findings are difficult for product teams to interpret
- Environmental claims exceed what the study supports
- LCA findings are not converted into design improvements

Frequently Asked Questions
A carbon footprint focuses on greenhouse-gas emissions. LCA may consider several environmental-impact categories across the life cycle.
It is a quantified description of the product or service function used as the basis for consistent calculation and comparison.
Primary supplier data can improve accuracy, but suitable secondary data may be used where primary information is unavailable.
Yes, but the comparison requires equivalent functions, consistent boundaries, suitable data and careful interpretation.
The duration depends on product complexity, boundaries, data availability and intended use.
Yes. Hotspot analysis can identify materials, processes, transport or use-phase impacts requiring improvement.
An EPD normally requires an LCA prepared according to applicable programme and product-category rules.
Preparation and independent verification should remain separate where formal assurance or programme approval is required.
