SECR carbon accounting you can defend.
IQCO₂ turns your activity data into SECR-ready reports — DEFRA-aligned calculations, a full audit trail for every number, and one place your finance and sustainability teams both trust.
What IQCO₂ is
Carbon accounting software, built specifically for UK SECR compliance reporting — not a general sustainability platform.
How it works
From activity data to an audit-ready report.
Enter activity data
Log electricity, fuel, travel, waste, and more — by category, by reporting period. Import by CSV or enter directly.
DEFRA factors applied automatically
The calculation engine applies the correct versioned DEFRA emission factor set for your period — no lookup tables, no manual maths.
SECR-ready report
Scope 1, 2 and 3 emissions broken down and totalled, ready to file — not a spreadsheet you have to reformat yourself.
Full audit trail
Every calculation is kept as an immutable record — inputs, engine version, factor set, and timestamp — for whoever has to sign off on it.
Who needs this
Large UK companies and LLPs are required to report under SECR.
The Streamlined Energy and Carbon Reporting (SECR) framework applies across sectors — these are the kinds of organisations IQCO₂ is built for.
Manufacturing
Commercial Property
Logistics
Education
Retail
Why IQCO₂
Built for the number you have to stand behind.
Defensible, not just fast
Every figure traces back to its inputs, engine version, and factor set — not a black-box total.
Factors kept current
DEFRA emission factor sets from 2019 through 2025 are built in and versioned — no manual lookup tables to maintain.
Less spreadsheet reconciliation
Activity data, calculations, and reports live in one place instead of scattered across exports and copy-pasted totals.
One source both teams trust
Sustainability teams enter the data; finance and compliance review the same audit trail — no separate versions of the truth.
