Carbon Accounting for UK Businesses
SECR-aligned, audit-ready sustainability reporting — built for UK SMEs and growing businesses.
UK carbon reporting requirements are expanding. Is your business ready?
The UK's Streamlined Energy and Carbon Reporting (SECR) framework already requires qualifying large companies to disclose emissions annually. The UK Sustainability Reporting Standards (UK SRS), aligned to IFRS S1 and S2, are now published and moving toward mandatory adoption for listed companies. Supply chain pressure means SMEs are next.
GreenKPO gives UK businesses a practical, fast-to-deploy way to measure Scope 1, 2 and 3 emissions — and produce the audit-ready evidence your clients, investors and regulators will ask for.
UK regulatory context
The UK carbon reporting landscape
The UK carbon reporting landscape has multiple active frameworks. GreenKPO is designed to satisfy the data needs of all of them:
SECR — mandatory for large companies
If your company exceeds two of: 250 employees, £36M turnover, £18M balance sheet, you must report Scope 1 & 2 emissions plus an intensity metric in your annual report.
SECR — Scope 3 voluntary but expected
Scope 3 reporting is not yet mandatory under SECR, but regulators and investors are increasingly expecting it. Consultations to mandate Scope 3 categories are ongoing.
UK Sustainability Reporting Standards
The UK has formally endorsed IFRS S1 and S2 with minor amendments. The FCA is consulting on mandatory UK SRS-aligned reporting for listed companies (CP26/5, open to March 2026).
Supply chain contractual pressure
Large UK corporates subject to SECR and UK SRS are already requesting emissions data from suppliers. For many UK SMEs, Scope 3 reporting is already a contractual requirement.
UK SME Voluntary Standard
The UK SME Voluntary Emissions Standard (2024) provides a consistent framework for smaller businesses. GreenKPO is aligned to it.
Government procurement
UK public procurement increasingly requires carbon data disclosure. Missing this can exclude your business from government tenders.

Act now
Why UK businesses should act now
SECR thresholds catch more companies than most realise — if you are approaching the two-of-three criteria, plan ahead.
UK SRS mandatory reporting for listed companies is imminent. Voluntary adoption builds competitive positioning now.
Large clients are already requesting Scope 3 data. Starting today gives you two years of clean historical data before it becomes obligatory.
UK net-zero by 2050 means carbon regulation will only tighten. Early movers build systems once rather than scrambling under pressure.
Investors and ESG-conscious customers treat credible carbon data as a trust signal — not just a compliance checkbox.
