Apply Life Cycle Thinking
Apply life cycle thinking — evaluating environmental impacts across all stages from raw material extraction through end-of-life — to identify where in a product or process's life cycle the highest impacts occur, and design or procurement decisions can reduce total impact.
Why This Is Best Practice
Adopted by: ISO 14040/44 (Life Cycle Assessment standards) are the international reference framework adopted by the European Commission, US EPA, and companies including BASF, IKEA, Procter & Gamble, and Unilever for product environmental claims and ecodesign decisions. The EU's Product Environmental Footprint (PEF) methodology and the UNEP/SETAC Life Cycle Initiative both build on ISO 14040/44. The EU Ecodesign for Sustainable Products Regulation (2024) requires LCA-based data for product categories sold in the EU.
Impact: Without life cycle thinking, environmental improvement efforts focus on the most visible stage (often manufacturing or disposal) rather than the highest-impact stage. Studies show that for many consumer products, 70–80% of environmental impact occurs during raw material extraction or use phase (e.g., energy consumption while in use) — not in production or disposal. LCA thinking prevents "pollution shifting" — a change that reduces one impact while increasing another is not an improvement.
