Cement is decarbonization's hardest case: ~60–65% of its CO2 is process chemistry — calcination of limestone releases CO2 regardless of fuel — and only ~35–40% comes from burning fuel in the kiln. That split dictates the strategy: efficiency and fuel measures attack the fuel share now; the calcination share ultimately needs clinker substitution or CCS. For the reporting desk that means: which frameworks bite, which KPI to disclose, and which completed measure to show. Here is the cement profile.
| Framework | Applies to cement? |
|---|---|
| EU ETS (if EU site) | Yes — full free-allocation phase-out applies |
| CBAM (if exporting to EU) | Yes |
| SECR (if large UK company) | Yes — energy, Scope 1+2, intensity ratio, efficiency actions |
| ESOS (if large UK undertaking) | Yes — audit by 5 Dec 2027 (Phase 4) + public action plan |
| CSRD / ESRS E1 (if large EU company) | Yes — actions (E1-3), targets (E1-4), energy (E1-5), Scope 1-3 (E1-6) |
| Customer SBTi / CDP requests | Sector-independent — arrives with the RFQ |
The intensity ratio your sector benchmarks against: ≈0.7 t CO2/t cement (clinker-driven; GNR/IEA range 0.5–0.9). SECR requires an intensity metric of your choice; ESRS E1-5 wants energy per net revenue; CBAM (where in scope) uses exactly t CO2 per tonne of product. Reporting the same physical KPI everywhere keeps the numbers reconcilable — and auditors happy.
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:
~35% of cement CO2 is fuel-side — the share efficiency measures can touch. Heat-loss surveys typically recover 2–5% of fuel use, i.e. 0.7–1.8% of this sector's total CO2, at sub-2-year payback. Worked example at a 500,000 t cement/yr site (≈350,000 t CO2/yr at the benchmark intensity): an insulation programme is worth 2,450–6,125 t CO2e/yr — a complete, verifiable entry for SECR disclosure 4, an ESOS progress update, ESRS E1-3 and the tender CRP, plus €189,630+ off the carbon bill where ETS/CBAM applies.
