When the board asks 'what decarbonization initiatives do we have?', this is the answer sheet: the proven dozen, with typical savings, paybacks and the report line each one produces. Efficiency first — it funds the rest.
| Initiative | Typical saving | Payback | What it does in the report |
|---|---|---|---|
| Heat-loss elimination (removable insulation on bare valves, flanges, fittings) | 2–5% of site fuel | <2 yr (often 9–11 mo) | Scope 1 ↓, SECR action, E1-3, tender CRP — negative net cost |
| Steam-trap survey & repair programme | 1–5% of steam fuel (10–20% of traps typically failed) | <1 yr | Scope 1 ↓ — the classic first-year initiative |
| Boiler combustion tuning / O2 trim | 1–3% of boiler fuel | <1 yr | Scope 1 ↓, zero capex variants exist |
| Economizer / flue-gas heat recovery | 3–8% of boiler fuel | 1–3 yr | Scope 1 ↓, named line item for E1-3 CapEx |
| Condensate return improvement | 1–5% of steam system energy | <2 yr | Scope 1 ↓ + water + treatment chemicals |
| Compressed-air leak programme | 10–30% of compressor electricity | <1 yr | Scope 2 ↓ |
| VSDs on pumps & fans | 20–50% of the drive's electricity | 1–3 yr | Scope 2 ↓ |
| LED + controls retrofit | 50–70% of lighting electricity | 1–3 yr | Scope 2 ↓ — visible, employee-facing |
| Waste-heat to process preheating | site-specific, often 5–15% of a stream | 2–4 yr | Scope 1 ↓, strong E1-1 transition-plan entry |
| Industrial heat pump on low-grade heat | COP 3–5 vs gas heating of that duty | 3–7 yr (grid-price dependent) | Scope 1→2 shift; transition-plan flagship |
| On-site solar PV / PPA | per sizing | 5–9 yr (PPA: 0 capex) | Scope 2 ↓, market-based reporting |
| Electrification of process heat (selected duties) | duty-specific | project | Scope 1→2; the structural 2030s lever |

Quantify (method + meter), cost it, link it to a target, and write the line. The Carbon Savings Certificate does this for heat-loss initiatives in 30 seconds; the same structure (measure → method → kWh → t CO2e → € → target) works for every row above.

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.
