Our verdict on Persefoni
Persefoni is a cloud-based carbon accounting and sustainability management platform for organizations measuring, reporting, and reducing greenhouse-gas emissions. It supports Scope 1, 2, and 3 accounting, emissions-factor management, sustainability reporting, supplier emissions data exchange, analytics, decarbonization planning, and audit-oriented data controls. The free Pro plan is positioned for companies with low to medium operational complexity, making Persefoni a fit for teams that want to establish carbon accounting without starting with a paid tier.
Its strongest differentiator is the combination of accounting depth and reviewability. The Footprint Ledger provides calculation transparency, while audit history and data review workflows help teams examine emissions data and calculations. Custom emissions factors, automated data collection through integrations, and supplier emissions data exchange support both internal data gathering and external supplier collaboration. The platform is available through the web and API, with integrations for Amazon Web Services, Concur, Expensify, Google Sheets, Navan, and Utilities.
The published plans separate a free Pro tier from Advanced capabilities. Pro includes Scope 1–3 carbon footprint accounting, a Sustainability Report Builder, Copilot, and Help Center and self-serve resources. Advanced adds scalable carbon accounting, advanced analytics, decarbonization planning, integration capabilities, and advanced controls. AI anomaly detection and Copilot are useful for teams managing review and analysis workflows, while the broader feature set suits sustainability-focused and enterprise-scale organizations. Choose Persefoni for a free, structured starting point with supplier and audit workflows; teams needing Advanced controls and planning should evaluate the Advanced tier.
