What this page is
A structured reference page meant to be cited. Replace placeholders with your preferred sources (government + reputable datasets) and keep an update log.
Key points
- Define metrics clearly (rates, boundaries, contamination definitions).
- Separate measured values from estimates and assumptions.
- Note local variability (collection system, energy mix, distance, end markets).
Suggested source types
- Government statistics agencies
- Municipal annual reports
- Peer-reviewed LCAs or meta-analyses
- International datasets (with consistent definitions)
Update tip: add a “Last updated” date and a short methodology block.
