Carbon Accounting Software for UK SMEs
SECR-aligned, audit-ready sustainability reporting — built for UK SMEs and growing businesses.
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.
What is driving UK carbon reporting now
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.
How GreenKPO works
- Data from your existing systems — Pull in energy bills, IT asset data, financial data, travel records and supplier invoices. GreenKPO structures it for you.
- SECR-aligned Scope 1 & 2 calculation — Uses BEIS-aligned emission factors updated annually. Your output is ready to drop into your Directors’ Report.
- Scope 3 value chain tracking — Map your upstream and downstream emissions across all relevant GHG Protocol categories. Ready for UK SRS and supply chain disclosure.
- Intensity metric and year-on-year trending — SECR requires an emissions intensity ratio. GreenKPO calculates it automatically and tracks it over time.
- Audit evidence pack — Every data point is tagged, sourced and traceable. Designed to be handed to your statutory auditor with zero additional work.
- SME-friendly pricing and setup — No sustainability team required. Onboard in a 30-minute call. First report typically within five working days.
Why 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.

Built for practical SME reporting
GreenKPO is not an enterprise ESG platform. The workflow is built around data that finance and operations teams already hold — energy, fuel, vehicles, travel, purchases and supplier information — so UK SMEs can produce reliable emissions figures without a dedicated sustainability department.
What you can produce
Upload or enter business data, map it to an emissions category, calculate with an auditable methodology, review the result and produce outputs for customer requests, tenders, internal reporting or compliance preparation.
- Business carbon footprint
- Separate Scope 1, Scope 2 and relevant Scope 3 outputs
- Customer carbon-data responses and tender support
- Evidence for adviser or consultant review
Why the evidence matters
Figures should be tied to underlying evidence so they can be explained, reviewed and updated — not left only in a spreadsheet. That is how GreenKPO supports customers, tenders, management reporting and SECR-related preparation from one controlled dataset.
