Refinery CO2 is almost all combustion: process heaters and boilers (~65%), the FCC regenerator, hydrogen production. Energy is 50–60% of operating cost net of crude, so carbon and margin point the same direction — every wasted GJ is paid twice. For the reporting desk that means: which frameworks bite, which KPI to disclose, and which completed measure to show. Here is the oil refining profile.
| Framework | Applies to oil refining? |
|---|---|
| EU ETS (if EU site) | Yes |
| CBAM (if exporting to EU) | No — named in the pre-2030 CBAM extension review |
| 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: ≈0.2–0.3 t CO2/t throughput (Solomon/Concawe range). 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:
~95% of oil refining CO2 is fuel-side — the share efficiency measures can touch. Heat-loss surveys typically recover 2–5% of fuel use, i.e. 1.9–4.8% of this sector's total CO2, at sub-2-year payback. Worked example at a 5,000,000 t crude/yr site (≈1,250,000 t CO2/yr at the benchmark intensity): an insulation programme is worth 23,750–59,375 t CO2e/yr — a complete, verifiable entry for SECR disclosure 4, an ESOS progress update, ESRS E1-3 and the tender CRP, plus €1,838,250+ off the carbon bill where ETS/CBAM applies.
