Waste Treatment & Disposal Emission Factors

178 emission factors held in the GreenCalculus MasterBrain, drawn from IPCC 2006 Guidelines Vol 5 — Waste and UK Government GHG Conversion Factors 2026. Values are read live from the data layer on every page build, so nothing here is re-typed and nothing can drift from the figures the calculators use. They span 34 units of measurement — 28 of them in fraction — which is why the spread below is reported per unit and never blended. The count includes 2 water supply and treatment factors, a family too small to warrant a page of its own and published nowhere else.

Where these factors are used

Waste Stream Emissions and Landfill Gas and Wastewater Treatment Emissions set out how factors in this group are applied, and Scope 3 Cat 5 Waste Streams Calculator and Landfill Gas & Wastewater Treatment Emissions Calculator draw on them directly. The published dataset these rows are drawn from is Waste Treatment & Disposal Emission Factors, which carries a DOI for citation.

What this group contains

Figures are computed per unit and never blended: a median across different units would be arithmetically valid and physically meaningless. 21 further units in this group have fewer than 3 factors and are counted above but not described.

Values change between editions. Quoting the MasterBrain version is what lets a reader resolve the exact number you used — see the change record above for factors in this group that have moved.

Both responses carry an X-GC-Version header, so a consumer can detect a new edition without diffing the payload. The CSV filename carries the edition too, so two downloads months apart do not collide.

All factors

Last changed names the data-layer edition in which a factor last took a new value, reconstructed from every released edition since v2025.13. A dash means the value has not moved since tracking began — which is the answer to "is the figure I used last year still current?".
