How to evaluate ESG & Sustainability

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Persefoni. It comes from our Sustainability & ESG Reporting buyer guide.

25%
Carbon-Accounting Methodology & Data Quality
GHG Protocol alignment across Scope 1/2/3, location- and market-based Scope 2, breadth and currency of emission-factor libraries, calculation transparency (can you trace a number back to activity data and the factor used), versioning of methodologies, and restatement handling when factors change
20%
Scope 3 & Supplier Engagement
Coverage of all 15 Scope 3 categories, ability to move from spend-based estimates to supplier-specific primary data, built-in supplier surveys and outreach, product-level and category footprints, and how the platform documents the primary-vs-secondary data split that ESRS E1 now requires
20%
Regulatory Framework Coverage & Re-mapping
Current support for CSRD/ESRS, ISSB (IFRS S1/S2), California SB 253/261, CDP, GRI, SASB, and CBAM; how quickly the vendor ships framework updates; and — critically given 2025’s upheaval — whether one emissions dataset re-maps across frameworks rather than being locked to a single regime
15%
Auditability & Assurance Readiness
Immutable audit trail of who changed what and when, evidence and document linkage, internal controls and approval workflows, prior-period locking, auditor/assurer access, and a track record supporting limited and reasonable assurance engagements
12%
Data Integration & Source Connectivity
Connectors to ERP, procurement, utility/energy, travel, and HR systems; utility-bill and meter ingestion; API and data-pipeline coverage; data-quality validation on ingest; and fit with your existing cloud and identity (SSO/SAML, RBAC)
8%
Decarbonization Planning, Targets & Usability
Science-based target setting and tracking, scenario and reduction-pathway modeling, initiative/abatement management, and whether non-specialist contributors across the business can actually enter and review data without a consultant
