What Good Looks Like in Carbon Management Software in 2026: The Table Stakes, and What to Ask for Above Them

A carbon management RFP that lists data ingestion, GHG Protocol calculations, audit-ready logging and supplier portals will get a yes from every vendor. Verdantix calls those features table stakes. Four questions above that line separate vendors, and each can be tested on your own purchase data. DitchCarbon answers each one below.

What does Verdantix call table stakes in carbon management software?

Verdantix names manual data ingestion, GHG Protocol-aligned calculations, audit-ready logging and supplier portals as the baseline. In Verdantix Green Quadrant For Carbon Management Software Reveals How Leading Providers Are Defining A New Era (18 March 2026), Alessandra Leggieri introduces the Green Quadrant: Enterprise Carbon Management Software (2026). The research evaluated 21 providers using a 91-point questionnaire, two-hour live demonstrations and 38 buyer interviews.

What are buyers asking for beyond the baseline?

Verdantix reports three things. Buyers want real-time visibility at asset, product and supplier level, beyond static reports. Pressure for product carbon footprints is pushing firms toward automated, auditable and standardised workflows. AI counts as a differentiator when it removes manual bottlenecks, for example emission factor matching or flagging anomalies before audits.

What should procurement ask above the table stakes?

Each table stakes feature has a question that separates one vendor from the next:

Table stakes featureThe question that separates vendorsData ingestionCan it take our ERP purchase data as it is, and what happens to lines it cannot match?GHG Protocol-aligned calculationsWhich method produced each line, and how many rest on a sector average?Audit-ready loggingIs the log backed by a verification of the calculation method, and to which standard?Supplier portalsHow much of my supplier list has usable data before any request goes out?

Can DitchCarbon take ERP purchase data as it is?

Yes. DitchCarbon takes ERP purchase data as it is, and matches from a company name alone where that is all the list holds. A spend export is the minimum. Where quantities and units are available, lines move up to activity data, and product-level detail lets a published product carbon footprint match to the line.

Which method produces each Scope 3 line in DitchCarbon?

Each figure is a hybrid calculation: the most accurate method available for every line, with an industry factor used only where nothing above it exists. DitchCarbon calculates on product data, activity data and supplier-specific (primary) spend, and only when all else fails, industry-level spend. Every figure shows which method produced it, and the share of a baseline still on an industry factor is shown as a number.

Is DitchCarbon's audit-ready logging backed by verification?

Audit-ready means an auditor can follow the figure: every figure carries its source and change history. The DitchCarbon calculator is verified to ISO 14064-3, limited assurance, by UL Solutions, renewed annually. DitchCarbon was the first company to earn UL Solutions' Sustainability Information Calculator Verification, in June 2025, and it is the only specialist Scope 3 tool with third-party assurance of its calculation methodology. The table of every vendor we checked is in Who's Really Verified? A Reality Check on Carbon Software Assurance, and the documents are in the trust centre.

How much of a supplier list does DitchCarbon cover before any request goes out?

A Category 1 baseline starts from verified emissions data for over 2 million organisations, built on primary emissions data wherever it exists, so suppliers and portfolio companies that have already published are covered before a request goes out. A recent deployment reached 70% coverage of emissions with primary data within 2 weeks. For the detail a buyer still needs, the request goes out prepopulated with what the supplier has already published, and the supplier adds the rest. Where nothing comes back, the line shows that it still rests on an industry factor.

On DitchCarbon, each of the four answers is something a buyer can open on their own list: the method behind every line, the share still on an industry factor, the verification behind the log and the coverage before any request.
