In biology a life cycle is series of changes an organism goes through before returning its original state.
When it comes to greenhouse gas emissions (ghg) over a product’s life cycle there are five (5) stages.
- Stage 1: Materials Extraction
- Stage 2: Manufacturing
- Stage 3: Distribution
- Stage 4: Usage
- Stage 5: End-of-Life Management
