Total Lifecycle CO2 vs Product Lifespan
How to Calculate Product Lifecycle Impact
A lifecycle assessment (LCA) evaluates environmental impact from cradle to grave.
Lifecycle Stages
1. Raw materials: Extraction and processing 2. Manufacturing: Assembly and production 3. Transportation: Distribution to consumer 4. Use phase: Energy consumed during use 5. End of life: Disposal, recycling, or landfill
Formula
Total CO2 = Materials + Manufacturing + Transport + (Annual Use * Years) + End of Life
Example Calculation
A laptop with 10kg materials, 15kg manufacturing, 5kg transport, 20kg/year use, 5-year life, 3kg end-of-life.
- 01Use phase: 20 * 5 = 100 kg CO2
- 02Total: 10 + 15 + 5 + 100 + 3 = 133 kg CO2
- 03Annualized: 133 / 5 = 26.6 kg CO2/year
- 04Use phase share: 100 / 133 = 75.2%
