Persefoni vs Sphera

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 …

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.

A publicly traded company replacing a consultant-built spreadsheet will find that SpheraCloud Corporate Sustainability is purpose-built for this exact transition. The platform ingests activity data via questionnaires, manual import, and integration connectors, then applies emission factors from Sphera's Managed LCA Content (MLC) database (20,000+ annually updated, third-party-verified datasets) to calculate Scope 1, 2, and all 15 GHG Protocol Scope 3 categories without manual spreadsheet assembly. …

Limitations: While Sphera's consulting layer and methodology documentation clearly distinguish spend-based, LCA/average-data, and supplier-specific PCF methods at the category and project level, publicly available documentation does not confirm that the per-record primary-vs-estimated flag is automatically surfaced as structured me …

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 an unauditable spreadsheet, Sphera's SpheraCloud platform provides an end-to-end traceable data lifecycle across its Environmental Accounting and Corporate Sustainability modules. As documented in Sphera's own product and blog content, the integrated platform creates a traceable audit trail that records each stop on a data point's journey, from who touched it to how it was processed, covering ingestion from external systems through calculation, validation, and regulatory reporting output. …

Limitations: Sphera's public documentation confirms traceable, auditable data lineage and auditor-facing visibility into calculation logic, but does not explicitly specify whether the underlying event log uses cryptographic immutability or append-only write-protection to prevent post-hoc alteration of the log itself; buyers pursuin …

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 SEC- and CSRD-consistent target progress reporting, Sphera delivers this requirement through SpheraCloud Corporate Sustainability, which operates as a single platform where the same verified GHG inventory drives both external disclosure output and internal target tracking. Within the platform's 'Targets and Actions' capability, buyers configure science-based or internally defined reduction targets at any level of the organizational hierarchy: by scope (1, 2, 3), by business unit, or by operating asset, then track actual emissions trajectories against those targets over time. An independent analyst report (Verdantix Green Quadrant) …

Limitations: Deeper abatement scenario modeling, including transition planning methodology spanning GHG inventory forecasting, feasibility assessment, and carbon abatement cost analysis, is documented primarily as a consulting-assisted capability (Sphera's sustainability consultants engage alongside the software), which means the s …

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.

For a publicly traded company replacing a consultant-built annual spreadsheet with an auditable pipeline, SpheraCloud Corporate Sustainability (SCCS) covers three of the four required source types with documented mechanisms. For ERP spend data, Sphera's brochure states that 'SCCS integrates seamlessly via API, pulling all your metrics into one centralized platform' from existing ERP, fleet management, and asset management systems, and Sphera holds SAP-certified integration with SAP S/4HANA and NetWeaver (with a dedicated 'Streamline data management with the corporate sustainability API connector' webinar). …

Limitations: No evidence of a named, pre-built corporate travel system connector was found, leaving that source type dependent on custom API work or manual import; and while Sphera documents audit trails and traceability broadly, public documentation does not confirm a per-record lineage layer that captures the source system identi …

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 …

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 replacing a consultant-built spreadsheet with auditable supplier data flows, Sphera provides multiple dedicated mechanisms within its Supply Chain Sustainability module and SpheraCloud platform. The Product Carbon Footprint Assessment is pre-configured and ready to send: the buyer loads suppliers, launches a campaign, and suppliers respond directly within the platform with product-level carbon footprint data; the tool automatically scores data quality of reported PCFs, captures supporting documentation and verification details, and matches supplier PCFs to the buyer's existing product codes. …

Limitations: The clearest platform-level documentation of the campaign-to-inventory data flow sits within the Supply Chain Sustainability module (formerly SupplyShift), and the automated provenance tagging of primary vs. …
