Persefoni vs Sweep

Requirement evaluated: The platform must calculate a full Scope 1, 2, and 3 greenhouse-gas inventory aligned to the GHG Protocol, explicitly covering the hard Scope 3 categories (purchased goods and services, upstream and downstream transportation, use of sold products, investments, and employee commute) without requiring manual spreadsheet assembly. Each category calculation must identify whether the underlying activity data is primary (supplier-measured) or estimated (spend-based or average-data method), with that distinction surfaced in the output.

For a publicly traded company replacing a consultant-built spreadsheet with an auditable inventory, Persefoni's integrated Emissions Calculation Engine ingests activity and spend data and calculates a full Scope 1, 2, and 3 inventory without manual spreadsheet assembly. <cite index="12-1">The engine is aligned with both the Greenhouse Gas Protocol and the Partnership for Carbon Accounting Financials (PCAF), leverages a global set of out-of-the-box emission factors, and allows creation of custom emission factors unique to the business.</cite> All 15 GHG Protocol Scope 3 categories are pre-built into the platform. …

Limitations: The AI-powered natural language emission factor mapping for spend files (which would further automate Category 1 spend-based calculations) is <cite index="5d7bd313-950f-48fb-a5d5-95d0b52d1bf9">labeled 'Coming Soon'</cite>, so buyers relying on automated spend-file-to-emission-factor mapping at scale today will need to …

For a publicly traded company replacing a consultant-built annual spreadsheet, Sweep ingests activity data from across the value chain (ERP spend, utility, travel, and supplier submissions) into a centralized platform and calculates a full Scope 1, 2, and 3 GHG inventory without manual spreadsheet assembly. <cite index="1b6a845e-c5f6-4d28-a5e9-e4e31ebdb13c">Sweep describes carbon accounting as 'a data and a network problem' and automates data collection across complex organizations to measure and manage Scope 1, 2, and 3 emissions.</cite> For Scope 3, the platform covers the full set of GHG Protocol categories: <cite index="31-1,31-2">Sweep's carbon accounting page documents measurement of S …

Limitations: Sweep's documentation describes data lineage and immutable audit trails at the inventory level, but does not publicly detail whether the primary-vs-estimated tag appears as structured per-record metadata on every output line item versus as an auditor-navigable lineage trail; buyers should confirm in a demo that this di …

Requirement evaluated: The platform must maintain a complete, immutable audit trail covering every data input, emission factor selection, calculation step, methodology change, and user action, sufficient to support third-party limited assurance engagements without supplemental documentation from the buyer. The audit trail must be exportable in a format that an external assurance provider can independently review, directly addressing the buyer's stated problem that the current spreadsheet is not auditable.

For a publicly traded company replacing an un-auditable consultant spreadsheet, Persefoni's Footprint Ledger is the core mechanism. The platform's named 'Activity & audit logs' feature records every data addition, modification, and deletion alongside the identity of the user who made the change, directly addressing the buyer's stated problem of non-auditable spreadsheet processes. …

Limitations: Persefoni's public documentation describes the audit log in terms of user-stamped add/modify/delete events and per-calculation factor visibility, but does not publicly document cryptographic immutability (e.g., hash-chaining or write-protected append-only storage) …

The audit trail must be exportable in a format that an external assurance provider can independently review, directly addressing the buyer's stated problem that the current spreadsheet is not auditable.

For a publicly traded company replacing a non-auditable consultant spreadsheet, Sweep's platform page explicitly commits to 'complete traceability and immutable audit trails for external assurance' and states that 'complete data lineage, immutable audit trails, and governance controls mean you can answer any auditor question with confidence, meeting mandatory assurance requirements under CSRD.' The platform centralizes emissions data from all sources, applies built-in governance controls and validation templates, and positions itself as providing audit-ready data from a single trusted source. …

Limitations: Sweep uses the language of immutable audit trails and complete data lineage in its marketing, but no public documentation found describes the technical depth at the level this buyer requires: whether emission factor vintage is version-locked per calculation, whether field-level before/after values are captured on every …

Requirement evaluated: The platform must support science-based or internally defined decarbonization target setting, allow the buyer to track actual emissions trajectories against those targets by scope and business unit, and model abatement scenarios. This capability must be connected to the same verified inventory data used for external disclosure, so that target progress reporting is consistent with the publicly disclosed figures required under the SEC and CSRD regimes.

For a publicly traded company needing target progress to reconcile exactly with SEC and CSRD disclosed figures, Persefoni addresses this through two connected components that both draw from the same Footprint Ledger inventory. First, the 'Reduce Footprint' feature, embedded in the core Climate Management and Accounting Platform (CMAP), lets users model percent-reduction scenarios across Scopes 1, 2, and 3 individually, visualize year-over-year progress against a target reduction goal, and identify which footprint sources offer the greatest abatement opportunity. …

Limitations: Publicly available documentation for CTM and Reduce Footprint describes tracking against a 'corporate target' and scope-level decomposition, but does not explicitly confirm that sub-targets can be configured at the business-unit or subsidiary hierarchy level and rolled up to the consolidated group total; buyers with ES …

Requirement evaluated: The platform must support science-based or internally defined decarbonization target setting, allow the buyer to track actual emissions trajectories against those targets by scope and business unit, and model abatement scenarios. This capability must be connected to the same verified inventory data used for external disclosure, so that target progress reporting is consistent with the publicly disclosed figures required under the SEC and CSRD regimes.

For a publicly traded company needing its decarbonization targets, trajectory tracking, and scenario modeling to be numerically consistent with SEC- and CSRD-disclosed figures, Sweep's architecture directly addresses this requirement through its three-pillar 'Track, Disclose, Act' platform, where all three functions operate against the same verified inventory dataset rather than separate copies of it. …

Limitations: Sweep's published documentation describes scenario modeling and trajectory tracking at a product-marketing level of detail; the specific mechanism by which forward-looking scenario outputs are version-locked to the same audited inventory snapshot used for external disclosure (preventing divergence between internal plan …

Requirement evaluated: The platform must ingest activity and spend data from at least four named source systems: utility bills, ERP spend exports, corporate travel systems, and supplier survey responses. Each data connection must maintain a documented lineage record showing the source, ingestion timestamp, and transformation applied, replacing the current consultant-built annual spreadsheet with a continuously updatable data pipeline.

For a publicly traded company replacing a consultant-built spreadsheet with a continuously auditable pipeline, Persefoni's Integration Hub provides named connectors to each of the four required source types: 9,000+ utility providers for Scope 1/2 consumption data, SAP Concur and Navan/TripActions for corporate travel activity, NetSuite and SAP Ariba/Coupa for ERP spend exports, and the Scope 3 Data Exchange module for supplier survey responses. Once connections are authenticated, the platform automatically extracts activity data on a configurable cadence and calculates footprints. …

Limitations: The documented audit log captures user-action timestamps and per-calculation factor transparency, but available public documentation does not explicitly confirm that connector-level ingestion events are stamped and stored as individual provenance records per raw activity row (versus per-import batch or per-user action) …

Requirement evaluated: The platform must ingest activity and spend data from at least four named source systems: utility bills, ERP spend exports, corporate travel systems, and supplier survey responses. Each data connection must maintain a documented lineage record showing the source, ingestion timestamp, and transformation applied, replacing the current consultant-built annual spreadsheet with a continuously updatable data pipeline.

Your scenario -- a publicly traded company replacing a consultant-built annual spreadsheet with a continuously auditable, multi-source data pipeline -- maps closely to Sweep's stated positioning. Sweep's platform page explicitly documents integration with ERP, procurement, and HRMS systems, and the sustainability reporting FAQ confirms the platform 'supports multiple integration methods including REST APIs, middleware connectors, SFTP file exchange, and direct connections to common ERP and finance systems.' A named 'Smart ETL engine' is described as being able to 'ingest, map, and transform data from virtually any source, acting as a centralized data fabric for sustainability information.' T …

Limitations: Corporate travel system integration is not documented with any named connector in public-facing materials, leaving one of the buyer's four required source types covered only by generic API language rather than a demonstrated pre-built integration. …

Requirement evaluated: The platform must include a supplier data collection module that enables the buyer to send data requests to suppliers, receive primary emissions data or product-level carbon footprints directly into the platform, and distinguish that primary data from spend-based estimates in Scope 3 Category 1 and other relevant categories. This replaces ad hoc supplier survey management and is required to improve data quality for the hard Scope 3 categories beyond the spend-based default.

For a publicly traded company moving off a consultant spreadsheet and toward assurance-grade Scope 3 reporting, Persefoni addresses this requirement through two integrated, natively built components: the Scope 3 Data Exchange module and Persefoni Pro. The buyer's sustainability team initiates the workflow inside the platform by sending auditable data requests to suppliers; suppliers do not need to be existing Persefoni customers, and those who have never calculated a footprint can respond by creating a free Persefoni Pro account to measure and share their own emissions. …

Limitations: Published documentation describes requests as 'auditable' and the workflow as replacing spend-based estimates, but granular technical detail on exactly how the platform tags incoming supplier responses as 'primary data' versus retained spend-based estimates in the calculation engine (the precise provenance distinction …

Requirement evaluated: The platform must include a supplier data collection module that enables the buyer to send data requests to suppliers, receive primary emissions data or product-level carbon footprints directly into the platform, and distinguish that primary data from spend-based estimates in Scope 3 Category 1 and other relevant categories. This replaces ad hoc supplier survey management and is required to improve data quality for the hard Scope 3 categories beyond the spend-based default.

For a publicly traded company moving off ad hoc spreadsheet-based supplier surveys toward auditable Scope 3 primary data collection, Sweep offers a dedicated supplier engagement layer branded 'Sweep for Supply Chain,' which operates as an integrated module within the main platform rather than a standalone survey tool. The buyer's procurement and sustainability teams use supplier portals and automated data collection tools built into the platform to send structured data requests to individual suppliers, segment them by emissions impact and spend exposure, and receive emissions data directly into the platform's carbon inventory — eliminating the manual re-entry and broken audit trail of the cu …

Limitations: Sweep's publicly available documentation describes the supplier portal and data lineage concepts at the product and marketing level, but does not publish granular technical detail on exactly how the platform tags and systematically overrides a specific spend-based estimate with a supplier-submitted primary data point a …
