In their own words
Persefoni
Persefoni provides software for organizations to measure and report carbon footprints, work on decarbonization, and manage sustainability disclosures. Its Pro and Advanced plans cover Scope 1, Scope 2, and all 15 Scope 3 categories. The Sustainability Report Builder guides disclosure work using qualitative responses and emissions data for frameworks including CSRD, ISSB, and CDP. Persefoni Copilot offers in-app carbon accounting support, while PersefoniAI can detect data anomalies; natural-language emission factor mapping is listed as coming soon. Integrations include Amazon Web Services, Concur, Expensify, Google Sheets, Navan, and utility providers. Advanced includes APIs and an Integration Hub for data ingestion. Persefoni describes the service as multi-tenant SaaS hosted on AWS, with encryption at rest using AES 256 and in transit using TLS 1.2 or above. The free Pro plan is limited to one user and excludes detailed GHG Metrics Reports. Advanced allows unlimited users, with pricing available by demo request. Personalized Concierge Support is a paid upgrade; all users can access the Help Center, guides, and tutorials.
