Replacing clinker with slag, fly ash, calcined clay or limestone filler cuts cement's process CO2 in direct proportion — the sector's biggest near-term lever.
| Metric | Value | Note |
|---|---|---|
| Abatement cost | ≈€0–30/t CO2 | |
| Addresses | 20–35% of cement CO2 | of relevant emissions |
| Typical payback | 1–3 yr | |
| Carbon value at full price | €80.01/t avoided | EUA July 13, 2026 |
LC3 (calcined clay + limestone) reaches ~40% clinker reduction with local clays — the technology transfer story of the decade for cement. Constraints are standards and customer acceptance, not chemistry. Every 10% clinker substitution ≈ −7% cement CO2.
Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes Inzonex Modular Insulation — snap-fastened modules engineered per temperature tier, not generic off-the-shelf jackets:
Every tonne you stop emitting is a tonne you don't have to report: cutting heat loss is a measurable, auditable Scope 1 reduction that flows straight into EU ETS, CBAM and your ESG / CSRD disclosures — not an offset, an actual emission cut.
