    Study Notes

    Introduction to Life Cycle Assessment

    • Life Cycle Assessment (LCA) is a quantitative method used to assess the environmental impact of a product throughout its lifecycle, from the extraction of raw materials to its disposal.
    • LCA is used as a decision-making tool for sustainability management, helping organizations choose between multiple options.

    Importance of LCA

    • LCA is becoming increasingly important due to rising pressures from various stakeholders, including regulators, investors, consumers, employees, and competitors.
    • These pressures demand sustainable practices and environmental responsibility.
    • Companies using LCA can reduce risks and costs associated with resource scarcity, while developing more sustainable products and processes.
    • LCA helps organizations focus on specific environmental and social needs by targeting areas for improvement and innovation.

    Life Cycle Thinking

    • Life Cycle Thinking (LCT) moves beyond traditional production-focused approaches to consider a product's overall impact throughout its lifecycle.
    • It seeks to integrate environmental, social, and economic factors.
    • LCT encourages a holistic perspective, recognizing the interconnectedness of different life cycle stages and the potential for innovation.

    Life Cycle Management (LCM)

    • LCM encompasses practices for managing information and activities related to a product or service's lifecycle.
    • Its goal is continuous improvement by considering sustainability at all stages.
    • LCM involves integrating sustainability into various aspects of a business, including strategic planning, product design, purchasing decisions, and communication policies.

    LCA Framework

    • LCA follows a structured framework with four phases:
      • Goal and Scope Definition: Defining the study's objectives, boundaries, and key considerations.
      • Inventory Analysis: Quantifying resource inputs and environmental outputs for each life cycle stage.
      • Impact Assessment: Evaluating the environmental consequences of the identified inputs and outputs.
      • Interpretation: Analyzing the results and drawing conclusions to inform decisions.

    Goal & Scope Definition: Key Elements

    • System Boundaries: Determining which parts of the lifecycle will be included in the study (e.g., "cradle to gate," "cradle to grave," "cradle to cradle").
    • Cut-off Rules: Establishing criteria for excluding specific activities or inputs based on factors like:
      • Physical measure (e.g., % total mass)
      • Cost or revenue contribution (e.g., % total cost)
      • Environmental aspects contribution (e.g., % total impact).
    • Location: Determining the geographical locations associated with each life cycle phase.
    • Functional Unit: Defining the specific function the product is intended to perform, providing a basis for comparison between different options.
