Every figure on this hub is dated and sourced. This page lists the sources, the update cadence, and — just as important — what we do NOT know precisely.

Prices are snapshots, not live feeds — the as-of date is printed wherever a price is used. National tax rates: World Bank State & Trends of Carbon Pricing 2025 and ICAP Allowance Price Explorer; approximate rates are marked with ≈.
The free-allocation phase-out and CBAM phase-in are not our model — they are Annex provisions of Regulation (EU) 2023/956: 2.5% payable in 2026 → 48.5% in 2030 → 100% in 2034. Any future EU amendment would change these numbers; we track the regulation as in force.
Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:
| Sector | Default | Notes |
|---|---|---|
| Cement | 0.70 t CO2/t cement | clinker-driven; range 0.5–0.9 |
| Steel — BF-BOF | 1.90 t CO2/t steel | integrated route; range 1.8–2.2 |
| Steel — EAF | 0.40 t CO2/t steel | scrap-based, direct; grid-dependent |
| Aluminium | 1.60 t CO2/t Al | smelting direct; indirect (power) can add ~10 t |
| Ammonia/fertilizer | 2.00 t CO2/t NH3 | SMR route; range 1.6–2.4 |
| Power — gas CCGT | 0.37 t CO2/MWh | 55–60% efficiency |
| Power — coal | 0.95 t CO2/MWh | subcritical–supercritical range |
Typical literature/benchmark values (IEA, EU ETS benchmarks) for indicative calculation only — your verified MRV data replaces them in any real assessment, and the calculator lets you enter t CO2 directly.
Facility tables use Climate TRACE satellite-derived estimates (2023 vintage) — independent, global, but modelled: individual-facility error can be ±20-30%. They are labeled «est.» everywhere and are NOT verified declarations. EU installations' verified EU ETS data exists separately at registry level. If a figure for your facility looks wrong, tell us — we correct on evidence.
