IBM Envizi carbon accounting software

IBM Envizi is IBM’s ESG data management and reporting software, which IBM describes as “a proven compliance ready solution for ESG data” (ibm.com).

This page sets IBM’s description of the ESG suite, its carbon modules and its pricing model beside what SECR, UK SRS and the FCA’s rules require.

We have not tested Envizi and give it no rating.

IBM presents Envizi as a lens on sustainability performance: analytics, reporting and planning tools on one ESG dataset, with AI used, in its words, “where it matters”.

The product page groups the modules in two.

Emissions management covers Scope 1 and 2 accounting, AI-assisted Scope 3, an emissions API for other software vendors, emissions calculations in Excel, Scope 3 financed emissions, and supply-chain intelligence for Scope 3 categories 1 and 2.

ESG reporting covers reporting frameworks, building ratings and benchmarks, surveys, planning analytics, programme tracking, utility-bill and interval-meter analytics, and target setting.

Underneath, IBM describes automated ingestion from ERP, metering, utility and supplier sources, configurable data tags so one dataset serves several outputs, organisational roll-ups, and data health checks with full audit trails.

These are IBM’s statements about its own product.

IBM describes a Scope 1 and 2 engine built on the GHG Protocol, and AI used to accelerate Scope 3 calculation.

UK SRS S2 asks for absolute gross Scope 1, 2 and 3 emissions to the GHG Protocol Corporate Standard, with location-based Scope 2 as the required figure (¶29(a)).

Every one of the fifteen Scope 3 categories must be considered, and the included ones disclosed (¶¶B32–B33).

IBM’s supply-chain intelligence module is described for categories 1 and 2, purchased goods and capital goods, so ask how the other thirteen are handled.

For banks, insurers and asset managers, ¶29A lets category 15 be limited to financed emissions; IBM’s financed-emissions module sits there, and PCAF’s standard is now in its third edition for Part A (2025).

For UK figures, ask which DESNZ conversion factor set was applied to each line and why.

The category rules are explained on Scope 3 under UK SRS and the standard on UK SRS S2.

IBM says every change in Envizi is logged with a full audit trail, that automated health checks monitor completeness, accuracy and timeliness, and that auditors can be given log-in access to the supporting data and documents.

The final FCA UK SRS rules do not impose a general requirement to obtain third-party assurance over these disclosures.

Listed companies in scope of the FCA rules state whether they obtained it and, if so, the provider, the disclosures covered and the standard used.

The practical test is a trace: one reported figure followed back, inside the system, to the bill or meter reading behind it.

One third-party view can be checked at its owner’s page: Verdantix’s 2026 Green Quadrant press release names IBM among eight Leaders in enterprise carbon management software, out of 21 vendors evaluated — Verdantix’s assessment, not ours.

If you file with CDP, its disclosure platform is where the response goes, and IBM names the frameworks CDP draws on.

Envizi’s pitch is the data layer, so the most useful requests test what comes out of it in UK form: an SECR section, location-based Scope 2 with its factor year, and a Scope 3 inclusion record.

The builder beside this text lists them with their provisions; mark each as shown on your data, described only, or not yet asked.

What the FCA’s rules ask of listed companies is on UK SRS compliance.

A fictional buyer asks IBM to demonstrate one utility record through site and group totals.
