Sweep carbon accounting software

Sweep sells carbon and ESG data software whose central claim is that data uploaded once can be used across every reporting framework (sweep.net).

It is one of the few vendors whose own pages name UK SRS, which makes the UK tests on this page directly relevant.

We have not tested Sweep and give it no rating.

Sweep describes itself as software that turns sustainability data into measurable business performance.

Its UK home page lists what it says the product helps with: staying compliant by uploading data once and using it across all frameworks, cutting operating costs, reducing supply-chain risk and building credibility with transparent ESG reporting.

Its reporting page is more specific: sustainability data, materiality assessment and disclosure in one workspace, mapped to CSRD, ISSB, GRI, CDP, SASB, TCFD, California SB 253 and SB 261, and UK SRS.

It describes connectors to ERP, HR, energy, procurement and travel systems; supplier portals for value-chain and Scope 3 data; and version control on every figure and narrative.

For assurance it describes an audit trail from raw input to filed disclosure and an interface that gives auditors direct access.

A separate financed-emissions module is aimed at banks, lenders and investors.

These are Sweep’s statements about its own product.

Sweep describes centralising carbon data across entities, sites and suppliers, and collecting supplier data in real time for Scope 3.

The UK SRS S2 tests are the same for every tool: gross Scope 1, 2 and 3 under the GHG Protocol Corporate Standard; location-based Scope 2 as the required figure; all fifteen Scope 3 categories considered and the included ones disclosed (¶29(a); ¶¶B30–B33).

Because Sweep also names the ESRS, a UK group reporting under both regimes will want both Scope 2 figures from the same data: the revised ESRS E1 requires market-based as well, UK SRS S2 does not.

For a financial institution, UK SRS S2 ¶29A allows Scope 3 category 15 to be limited to financed emissions, which is where Sweep’s PCAF-aligned module would sit.

PCAF’s standard is now in its third edition for Part A (2025); a module built on an earlier edition would need updating.

People searching for a Scope 1, 2 and 3 emissions calculator should note that a calculation is the start: UK SRS S2 needs the category record and the method behind each figure, explained on Scope 3 under UK SRS.

Sweep says every figure traces back to its source, with methodology and version history captured automatically, and that auditors can be given direct access.

Its reporting page also says Sweep supports “limited assurance under CSRD, reasonable assurance when it phases in”.

The law on that point changed in 2026: Omnibus I removed the empowerment to adopt reasonable-assurance standards, and CSRD assurance is a limited assurance engagement (Directive (EU) 2026/470, recital (5), Art 1(3)).

The final FCA UK SRS rules do not impose a general requirement to obtain third-party assurance; listed companies in scope state whether they obtained it.

One third-party view can be checked at its owner’s page: Verdantix’s 2026 Green Quadrant press release names Sweep among eight firms in its leading group — Verdantix’s assessment, not ours.

Sweep also names CDP among its frameworks; CDP’s own disclosure platform is where those responses go.

Because Sweep names UK SRS, the FCA listing-rule requests are worth putting to it directly: the comply-or-explain statement, the relief statement and the assurance statement.

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

The rules behind those requests are on UK SRS compliance.
