Study Notes

Life Cycle Thinking (LCT)

Holistic perspective beyond traditional manufacturing
Considers environmental, social and economic impacts throughout a product's lifecycle
Focuses on continuous improvement and sustainability
Essential for understanding consequences of choices in each life cycle phase
Offers potential for innovation by identifying opportunities and risks

Life Cycle Management (LCM)

Set of practices to manage information and activities related to product/service life cycle
Integrates sustainability into company strategy and planning
Encompasses product design, development, purchasing, communication policies
Promotes holistic view and understanding of interdependencies within an organization and between businesses

Life Cycle Assessment (LCA)

Quantitative method to assess environmental impacts of a product's entire life cycle
Used for decision-making in sustainability management, comparing multiple environmental options
Utilizes international ISO 14040 standards for consistency
Avoids "pollution shifting" by considering all environmental impacts throughout the lifecycle

LCA - The Four Steps

Goal & Scope Definition: Determining the purpose, boundaries, target audience, and unit of analysis for the LCA
Life Cycle Inventory (LCI): Quantifying the inputs and outputs of the product system through a process diagram
Impact Assessment: Evaluating the environmental impacts of the inputs and outputs using specific impact categories
Interpretation: Analyzing the results to identify improvement opportunities and inform decision-making

LCA - Additional Considerations

Pollution Shifting: Assessing the environmental impacts of a product's life cycle to ensure that pollution is not merely transferred from one stage to another
Elementary Flows: Inputs like resources and outputs like emissions directly released into the environment
Non-Elementary Flows: Intermediate products, materials, or waste exchanged between actors in the life cycle
Unit Processes: Components of the product system from which environmental impacts are quantified, such as raw material extraction, manufacturing, transportation, and use
Functional Unit (FU): The function of the product being assessed, clearly defining what the product delivers

Example of Life Cycle Thinking

T-shirt life cycle:
- Raw Material Extraction (cotton production): Impact on water consumption, pesticide use, soil erosion
- Manufacturing (processing into fabric): Impact on energy consumption, chemical emissions
- Distribution (shipping): Impact on transportation emissions
- Use (wearing): Impact on washing emissions, textile wear and tear
- End of Life (disposal): Impact on landfill space, potential for recycling or reuse

Life Cycle Management (LCM) – Key Aspects

Product Design: Incorporating environmental considerations into the design phase, such as reducing material usage and choosing sustainable materials
Supply Chain Management: Managing the flow of materials and information from suppliers to customers, ensuring sustainability practices throughout the chain
Production Processes: Optimizing production processes to minimize waste, emissions, and energy consumption
Marketing and Communication: Communicating the environmental benefits of products and services to customers
