Life Cycle Assessment: Uncover the True Environmental Impact of Your Products

Struggling to keep up with your college coursework? Let's get it done together.

Life cycle assessment methodology and applications - Solution

Goal And Scope Definition

We assist in establishing the purpose, system boundaries, functional unit, and audience for the LCA study to ensure clarity and relevance.

  • Define the specific objectives and intended application of the assessment.
  • Set the product system boundaries, determining which life cycle stages and processes to include.
  • Establish the functional unit, which quantifies the performance of the product system for fair comparison.

Inventory Analysis Compilation

We support the collection and calculation of data on all relevant inputs (energy, materials) and outputs (emissions, waste) for each process within the system boundaries.

  • Guide data collection from primary sources (e.g., site-specific measurements) and secondary sources (e.g., databases).
  • Help model the product system using flow diagrams and perform calculations to aggregate the total inputs and outputs.
  • Assist in managing data quality, addressing gaps, and ensuring consistency.

Impact Assessment Modeling

We aid in evaluating the magnitude and significance of potential environmental impacts using the inventory data, translating emissions into impact categories.

  • Select appropriate impact categories (e.g., climate change, water use, human toxicity).
  • Apply characterization factors to classify and aggregate inventory flows into impact category indicators.
  • Support optional normalization, weighting, and grouping steps to further interpret results.

Interpretation And Reporting

We facilitate the analysis of results, checking consistency, drawing conclusions, and communicating findings in line with standards like ISO 14040/44.

  • Identify significant issues based on inventory and impact assessment results.
  • Perform completeness, sensitivity, and uncertainty checks to evaluate the robustness of the study.
  • Help prepare transparent reports, summaries, or declarations (e.g., Environmental Product Declarations) for stakeholders.

Application Support

We provide guidance on applying LCA results to inform decision-making in areas such as product design, policy, marketing, and supply chain management.

  • Support comparative assertions between products for public disclosure.
  • Aid in eco-design and identifying environmental hotspots for improvement.
  • Assist in using LCA for strategic planning, procurement, and sustainability reporting.

Frequently Asked Questions (Q&A)

A: The key phases of an LCA, as defined by ISO 14040/14044, are: Goal and Scope Definition (setting the purpose and system boundaries), Life Cycle Inventory (LCI) - collecting data on energy and material inputs and environmental outputs, Life Cycle Impact Assessment (LCIA) - evaluating the potential environmental impacts, and Interpretation - analyzing results, drawing conclusions, and providing recommendations. This framework ensures a systematic and comprehensive evaluation.

A: LCA is applied to support eco-design of products, identify supply chain hotspots for improvement, develop environmental product declarations (EPDs) for marketing, inform corporate sustainability strategies, and shape environmental regulations and policies (e.g., eco-labeling criteria, carbon footprint regulations). It provides a science-based foundation for comparing alternatives and reducing overall environmental impacts.

A: Common challenges include data availability and quality (especially for upstream processes), defining appropriate system boundaries and functional units, selecting impact assessment methods and categories, dealing with allocation of multi-output processes, and interpreting results amidst uncertainty. These limitations require careful methodological choices and transparent reporting to ensure credible and useful outcomes.
