    Study Notes

    Importance of Life Cycle Approaches

    • Sustainability is a major trend impacting companies due to regulatory, investor, consumer, and stakeholder pressures, as well as competition, costs, and risk.
    • Companies can improve sustainability performance, gain competitive advantage, and enhance reputation by:
      • Reducing risks and costs of scarce resources
      • Developing more sustainable products, processes, or business models
      • Targeting specific environmental and social needs
    • Sustainable value creation involves increasing economic, social, and environmental worth of goods, services, or businesses while ensuring sustainability.

    From Life Cycle Thinking to Life Cycle Assessment

    • Life Cycle Thinking (LCT) considers the entire life cycle of a product, going beyond traditional production focus to include environmental, social, and economic impacts.
    • LCT is a mindset that integrates into business practices through life cycle management, policy, strategies, and systems.
    • Life Cycle Assessment (LCA) is a data-driven tool using various scientific methods to assess the environmental impact of a product or service throughout its life cycle.
    • LCA uses software, models, and databases to analyze environmental impacts and interpret results.
    • ISO 14040 and ISO 14044 are standards for the LCA framework, developed by the Society of Environmental Toxicology and Chemistry (SETAC), the United Nations Environment Program (UNEP), and the International Organization for Standardization (ISO).

    Life Cycle Assessment (LCA)

    • LCA is a standardized process with 4 main steps:
      • Goal and Scope Definition: Defining the purpose and scope of the LCA.
      • Inventory Analysis (LCI): Quantifying the inputs and outputs of each stage in the product's life cycle.
      • Impact Assessment: Evaluating the environmental impacts associated with the inputs and outputs identified in the inventory.
      • Interpretation: Analyzing the results and deriving conclusions.
    • LCA has direct applications in:
      • Product development and improvement
      • Strategic planning
      • Public policy making
      • Marketing

    Pollution Shifting

    • Pollution shifting occurs when environmental impact is transferred from one stage of the life cycle to another or from one geographic location to another.

    Life Cycle Inventory (LCI)

    • LCI is a quantitative list of inputs and outputs for a product or service.
    • Inputs are resources, such as raw materials and energy.
    • Outputs are emissions and waste products.
    • Information is organized into a process diagram.
    • The scope and goals of the study guide the LCI.

    ###Impact Assessment (LCIA)

    • LCIA aims to understand and evaluate the environmental impacts of a product or service.
    • It involves selecting a database and an impact assessment method.
    • The choice of database and method is based on:
      • Impact categories, including midpoint and endpoint.
      • Product and/or process.
      • Industry.
      • Specific environmental regulations, ecolabels, ecoprofiles.
      • Company environmental agenda.
      • Consistency with other studies.

    Impact Assessment (LCIA) - Midpoint and Endpoint Categories

    • Midpoint categories focus on environmental stress, while endpoint categories focus on human well-being.
    • There are many different categories that you can use.
    • Example categories : Acidification, Eutrophication, Global Warming, Ozone Depletion.

    Impact Assessment (LCIA) - Reconciliation of Flows

    • The process of turning raw data into meaningful information to determine impact involves 3 steps:
      • Classification: Categorizing inputs and outputs into one or more impact categories.
      • Characterization: Quantifying each flow into a common unit of measurement. Characterization factors are used to express the impact potential per unit of each substance.
      • Normalization and Weighting: >- Normalization: Adjusting the results using reference values to create a relative impact score. The score is relative to the average annual impact in the environment. >- Weighting: Assigning weight to different impact categories. The weights are subjective and reflect community values.

    Interpretation and Conclusion

    • Interpretation focuses on:
      • Analyzing the results to identify the major contributors to impacts.
      • Performing sensitivity and uncertainty analyses to evaluate the robustness of the results.
      • Providing recommendations for improvements.

    Sensitivity Analysis

    • Evaluates the extent to which variations in input data or assumptions affect the results.

    Uncertainty Analysis

    • Evaluates uncertainty in the data and in the model.
    • Uncertainty reflects gaps in knowledge or potential variability in real-world conditions.
    • Uncertainty can be quantified and communicated alongside the results.

    Decision Tree

    • A decision tree combines sensitivity and uncertainty information to identify the most important data to improve.
    • This helps to focus efforts and make informed decisions.

    Limitations of LCA

    • Data quality and model quality can severely impact the validity of the study.
    • LCA is a tool for comparing options, but does not tell us if a product or service is sustainable.
    • LCA only considers environmental impacts.

    Other Considerations

    • Environmental Life Cycle Costing (eLCC): incorporates environmental costs alongside monetary costs for a more comprehensive assessment of environmental and economic performance.
    • Social Life Cycle Analysis (S-LCA): considers social issues that are related to the product or service throughout its lifecycle. This helps to evaluate the social impacts of products and services.
    • Life Cycle Sustainability Assessment (LCSA) is a more holistic approach that combines LCA, eLCC, and other sustainability assessment methods for a more comprehensive and integrated evaluation of sustainability performance.

    Life Cycle Inventories (LCI)

    • An LCI quantifies the elementary flows (inputs and outputs) needed for a functional unit (FU).
    • It includes both resources and emissions, as well as secondary flows (intermediate and final products or waste).
    • LCI relies on a process diagram and aligns with the goals and scope of the Life Cycle Analysis (LCA).

    Impact assessment (LCIA)

    • LCIA evaluates the magnitude and significance of potential environmental impacts from the studied system.
    • Choosing the database and impact assessment method depends on factors like:
      • Impact categories (midpoint and endpoint)
      • Product or process
      • Industry
      • Environmental regulations
      • Ecolabels or ecoprofiles
      • Company's environmental agenda
      • Consistency with other studies.

    Impact Assessment Method

    • Three main steps for reconciling different flow quantities into specific impact categories:
      • Classification: Linking all flows (from LCI) to their corresponding impact categories.
      • Characterization: Expressing flows from LCI in terms of equivalent quantity of a reference substance using characterization factors.
      • Normalization and Weighting:
        • Normalization uses an exposure of reference (average annual impact) to create a relative impact.
        • Weighting assigns a relative importance to each impact result, allowing for a single score expressed in "points."

    Interpretation & Conclusion

    • Analyzing the results identifies the main contributors to the analyzed impacts.
    • Sensitivity analysis determines the extent to which variations in input parameters or choices affect results.
    • Uncertainty analysis addresses baseline assumptions and bill of activities data, clarifying the precision of the study and the robustness of its conclusions.

    Limitations

    • Many decisions are made throughout LCA, including:
      • Functional unit and scope definition
      • Type of LCA
      • Cut-offs
      • Impact categories
      • Allocations
      • Weighting

    Data and Model Quality

    • Uncertainties can arise from parameters (data quality, gaps), scenarios, and models (limited system knowledge).

    LCA ≠ Sustainability

    • LCA provides information on the best option, but not environmental sustainability.
    • Environmental Life Cycle Costing (eLCC) and Social Life Cycle Analysis (S-LCA) can help address this gap.
    • Sustainable LCA can provide a more holistic understanding of environmental, economic, and social impacts.
