Question

What carbon reporting is mandatory for industrial companies in 2026?

Answer

Depends on where you sit: large UK companies file SECR disclosures in the directors' report and complete ESOS audits (Phase 4 by 5 Dec 2027); large EU companies report under CSRD/ESRS E1 (first wave already reporting, later waves delayed by the 2025 Omnibus); EU importers of CBAM goods file the CBAM declaration from 2026; suppliers to net-zero-committed customers face contractual carbon questionnaires (SBTi/CDP); and UK public-sector bidders above £5M need a published Carbon Reduction Plan.

Hot industrial equipment? Cut the heat loss.

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:

  • Up to 90% less heat loss from insulated surfaces
  • Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
  • 6× faster maintenance access than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
  • Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
  • Typical payback under 2 years (some 9–11 months)
