Emitwise: no longer sold, and what an inventory built on it needs next
Emitwise is no longer sold as a standalone product: Green Project Technologies acquired its software in July 2025, and its technology now sits inside Green Project’s supply-chain products.
So this page is not a review; it records what Green Project says happened, read on 1 October 2026, and sets out what a company moving its carbon inventory off a withdrawn platform has to carry into its next report.
This site has tested no carbon software.
What happened to Emitwise
From product to component, in its owner’s words
The page at emitwise.com is now a transition notice headed “Emitwise is now Green Project Technologies”.
It says Green Project Technologies acquired Emitwise’s software solution in July 2025, and that the platform and the Emitwise team are now part of Green Project.
It answers the obvious question directly: Emitwise is no longer sold as a standalone product or brand.
The technology, the notice says, now powers Green Project’s supply-chain and product carbon footprint capabilities, packaged as suite50.
Green Project’s own account50 FAQ is more specific: Emitwise’s technology powers engage50, its supplier engagement product, and is not the same thing as account50, its carbon accounting product.
The notice sends anyone wanting product information, a demonstration or support to the Green Project website.

Green Project’s suite50
Three products, as Green Project describes them
Green Project announced suite50 on 1 October 2025 as a platform uniting supplier engagement, carbon accounting and renewable energy procurement, aimed at Scope 3.
Green Project describes itself as an ACT Group company.
Its account50 FAQ says the product uses activity-based accounting aligned with the GHG Protocol, and supports reporting for CDP, CSRD, SBTi, EDCI and EcoVadis.
SECR, ESOS and UK SRS are not named on the Green Project pages read.
account50 is, in Green Project’s words, an enterprise licence tailored to each organisation, priced on coverage, entities, complexity, integrations and assurance needs; no figure is published, so this site lists it as Enterprise level · TBD.
act50 sells energy attribute certificates, which affect a market-based Scope 2 figure.
UK SRS S2 requires location-based Scope 2 under ¶29(a)(v) and asks for information about contractual instruments only where it informs users, so certificates never replace the location-based figure.
| Product | What Green Project says it does |
|---|---|
| engage50 | Supplier engagement: free tools for suppliers to measure, track and reduce emissions and set targets. Emitwise’s technology now powers it. |
| account50 | Carbon accounting for Scope 1, 2 and 3 from primary supplier data, for corporate, product and service-level footprints |
| act50 | Access to a renewable energy certificate (EAC) marketplace for supplier decarbonisation |
Moving an inventory off a withdrawn platform
What the next report has to carry
When a carbon accounting product is withdrawn, the inventory does not move by itself; the company that reported the figures still owns them.
The first job is an export: activity data, every factor with its version, and the methodology notes, so each figure already published can be rebuilt.
The GHG Protocol’s consistency and transparency principles, in Chapter 1 of the Corporate Standard, are what make that record necessary rather than tidy.
The second is a reconciliation: last year’s published total, reloaded in the new tool, should come out the same, and any difference is either an error to correct or a method change to explain.
Factors are the commonest source of difference, because each DESNZ set is for activity data falling within its own year, under ¶1.10 of the 2026 methodology paper.
A new platform that re-runs old years on its own current library changes history without anyone deciding to.
The checker beside this lists what the next report has to carry, given what you report under and what the move changes.

Restatement
Does a change of software move the base year?
A base year is recalculated for significant changes — in the company’s structure, in calculation methodology, or for significant errors — according to the GHG Protocol’s 2019 Inventory Guidance.
The Corporate Standard sets no definition of “significant”; the company sets and discloses its own threshold.
A science-based target has its own rule: GHG Protocol’s technical assistance notes that the SBTi requires a significance threshold of 5% or less for recalculating target emissions.
A move that only re-keys the same data on the same method is not a methodology change.
A move that swaps the factor library, or switches Scope 3 categories from spend to supplier data, may be — which is why the test is the size of the effect, not the fact of the move.
The checker beside this walks the GHG Protocol test for structural changes; the method side is covered in the GHG Protocol.

The UK disclosures
SECR and UK SRS in the year of the switch
SECR keeps a two-year view: last year’s energy and emissions appear beside this year’s, under paragraphs 18 and 20H of Schedule 7, and a methodology statement describes the methods used.
The government’s guidance on each line is in the Environmental Reporting Guidelines, and the UK factor sets are in the DESNZ conversion factors collection.
For UK SRS S2, a change of platform that changes the measurement approach, inputs or assumptions is a disclosure: ¶29(a)(iii) of the standard asks for those changes and the reasons for them.
Where Scope 3 categories change method, the extent of Scope 3 measured from specific-activity and verified inputs, disclosed under ¶B56, changes with them.
Listed companies in UKLR 6, 14, 15, 16 and 22 report against UK SRS on a comply-or-explain basis for periods from 1 January 2027, under the FCA’s PS26/19, which replaced the CP26/5 proposal.
The standards themselves, UK SRS S1 and S2, were published by the Department for Business and Trade on 25 February 2026 for voluntary use.
The Scope 3 inventory a replacement must hold is defined by the GHG Protocol Scope 3 Standard, with exclusions disclosed and justified.
The SECR lines are on SECR requirements, and the comparatives on the SECR reporting guide.
Choosing what comes next
A replacement platform, tested on what it must produce
The checklist beside this lists what each UK regime requires a platform to produce, cited to the provision, so a replacement can be tested on outputs rather than features.
Other platforms profiled here in their owners’ own words include Normative and Sweep; every vendor is listed on carbon reporting software.
The measurement-layer tests that matter most after a forced move — factor versions, restatement, audit trail, export — are on carbon accounting software.

Frequently asked
Emitwise, answered from its owner’s pages
What happened to Emitwise?
Green Project Technologies acquired Emitwise’s software in July 2025.
The notice now at emitwise.com says the platform and the Emitwise team are part of Green Project, and that Emitwise is no longer sold as a standalone product or brand.
Is Emitwise still available?
Not as Emitwise.
Its owner says the technology now powers Green Project’s supply-chain and product carbon footprint capabilities, and directs anyone wanting product information or a demonstration to the Green Project website.
Is Emitwise the same as account50?
No, on Green Project’s own account.
Its account50 FAQ says Emitwise’s technology now powers engage50, Green Project’s supplier engagement product, and that engage50 and account50 together form part of its supply-chain decarbonisation platform.
What is suite50?
Green Project announced suite50 on 1 October 2025 as three products: engage50 for supplier engagement, account50 for carbon accounting, and act50 for buying renewable energy certificates.
Green Project describes itself as an ACT Group company.
Do I have to restate my base year if I change carbon accounting software?
Not because of the software itself.
Under the GHG Protocol a base year is recalculated for significant changes in structure, in calculation methodology, or for significant errors, measured against a significance threshold the company sets for itself; a new tool that changes factors or Scope 3 methods can be such a change, a tool that re-keys the same method usually is not.
What does SECR need from a company that changed platform mid-year?
The directors’ report still shows last year’s energy and emissions beside this year’s, and the methodology statement describes the methods used.
If the comparatives were restated on a new method, saying so lets a reader compare like with like.
How much does Green Project’s account50 cost?
Green Project says account50 is offered as an enterprise licence tailored to each organisation, priced on factors including Scope 1–3 coverage, number of entities and reporting complexity.
It publishes no figure, so this site records it as Enterprise level · TBD.
Has this site tested Emitwise or Green Project?
No. This site has tested no carbon software.
This page reports what Green Project publishes about Emitwise and its own products, dated, beside the UK provisions a change of platform touches.
