CLAIMBOUND / SOURCE-PUBLICATION EVIDENCE
Waste management
Every card identifies what it proves, what it does not prove, its exact quote, locator, source hash, and local rerun command.
1. IPCC Good Practice Guidance Chapter 5 Waste · PDF page 5
Narrow public claim
If the amount or composition of waste disposed of at SWDS is changing more rapidly over time, however, the IPCC default method will not provide an accurate trend.
What this card proves
The exact quoted statement occurred in the named official PDF fetched on 2026-09-06, and the complete PDF matched the recorded SHA-256.
What this card does not prove
It does not independently establish the underlying model capability, safety, comparison, or real-world truth. This is a retrospective single-maintainer source-publication audit.

Equation 5.1 is based on the derivative of the general FOD equation (see p 6.10, Reference Manual, IPCC Guidelines) with t replaced by t – x, representing a normalisation factor that corrects for the fact that the evaluation for a single year is a discrete time estimate rather than a continuous time estimate.
