Platform Review
Emitwise Review
Independent analysis of Emitwise for UK carbon reporting — a London-founded platform that used machine learning to close Scope 3 data gaps and drive supplier engagement for manufacturing supply chains, before its 2025 acquisition.
We cover SECR relevance, fit, and implementation.
Emitwise platform overview
Emitwise was a London-headquartered carbon accounting platform founded in 2019, specialising in AI-driven Scope 3 analytics for manufacturing enterprises.
The platform applied machine learning to estimate and fill supplier data gaps, surface the emissions hotspots that matter, and structure supplier-engagement workflows.
That focus addressed the hardest part of Scope 3 — sparse, inconsistent primary data from suppliers — directly, rather than treating it as an afterthought.
Emitwise was deliberately specialised: strong on supply-chain carbon and ML insight, less broad on whole-of-ESG governance and disclosure modules.
Green Project Technologies (ACT Group) acquired the Emitwise technology platform on 28 July 2025; it is described here as it operated before that acquisition.
SECR & UK reporting fit
Emitwise SECR and Scope 3 assessment
Emitwise produced GHG Protocol-aligned Scope 1, 2 and 3 figures that provided the basis for SECR disclosure, with particular strength in the Scope 3 categories most companies struggle to quantify.
Its supplier-engagement workflows and ML estimation improved primary-data coverage over time, which matters for credible value-chain reporting.
UK statutory SECR formatting was a lighter part of the proposition than its Scope 3 analytics; the platform was chosen primarily for supply-chain accuracy.
Robust Scope 3 data is foundational to UK SRS S2 reporting, and this was where Emitwise contributed most, for organisations assessing it before the 2025 acquisition.
Carbon inventories follow the GHG Protocol Corporate Accounting and Reporting Standard.
Scope 3 value-chain emissions span all 15 categories per the 3 GHG Protocol Scope 3 Standard — purchased goods and services (Category 1) and upstream transportation and distribution (Category 4) are typically the largest for manufacturers.
UK energy conversion uses 4 DESNZ government conversion factors.
Large UK companies in scope of the Streamlined Energy and Carbon Reporting (SECR) regulations must comply with them.
The UK SRS S2 standard asks preparers who choose to report against it to disclose Scope 3 value-chain emissions — but UK SRS remains voluntary today, and no entity is yet required to report against it.
The FCA's CP26/5 consultation proposes moving UK SRS S2 climate reporting to mandatory for in-scope listed issuers from January 2027, while keeping Scope 3 reporting on a comply-or-explain basis rather than mandatory; the FCA has not yet published a Policy Statement.
Companies with science-based targets should align supplier engagement with 8 SBTi supply-chain requirements.
| Capability | Emitwise | Implementation effort | UK alignment |
|---|---|---|---|
| Scope 3 estimation | AI / ML-driven | Standard setup | Strong |
| Supplier engagement | Built-in workflows | Standard setup | Strong |
| Manufacturing fit | Sector-tuned | Standard setup | Strong |
| SECR statutory format | Supported, not the focus | Configuration | Moderate |
| Whole-of-ESG governance | Limited | N/A | Limited |
"Emitwise picks the hardest carbon problem — supplier Scope 3 data — and points machine learning straight at it. For manufacturers, that focus is the point."Supply-chain carbon analysis
Fit & implementation
Where Emitwise fits
Emitwise suited manufacturing enterprises with complex supply chains, where Scope 3 dominates the footprint and supplier engagement is the priority.
Its ML-based gap-filling and hotspot analysis were the platform's decisive advantages for these organisations.
Green Project Technologies (ACT Group) acquired Emitwise on 28 July 2025, and the technology is no longer sold as a standalone platform; prospective buyers are now routed to the acquirer's suite50 platform, so implementation now runs through that route rather than a direct Emitwise deployment.
Organisations wanting an all-in-one ESG and governance suite, rather than deep Scope 3, may prefer a broader platform.
What is Emitwise best known for?
Emitwise specialises in AI-driven Scope 3 analytics for manufacturing supply chains.
It uses machine learning to fill supplier data gaps, surface emissions hotspots and run supplier-engagement workflows — tackling the most common Scope 3 problem, poor primary data.
Is Emitwise a UK platform?
Emitwise was founded in London in 2019 with a product oriented to UK and European carbon accounting needs, including SECR-relevant Scope 1–3 reporting.
It was acquired by Green Project Technologies (ACT Group) in July 2025 and is no longer sold as a standalone platform; emitwise.com now routes to the acquirer's suite50 platform.
Who is Emitwise best for?
Manufacturing enterprises with complex supply chains where Scope 3 dominates the footprint and supplier engagement is the priority — rather than organisations seeking a broad, all-of-ESG governance suite.
Does Emitwise cover SECR?
Emitwise produces GHG Protocol-aligned Scope 1, 2 and 3 figures that support SECR disclosure; its emphasis is supply-chain (Scope 3) accuracy rather than statutory templating.
