Which brand does AI favour?Answers collected Mar 17 – Sep 10, 2026
The answers split on target audience, with some recommending Persefoni for strict auditor access and others choosing Watershed for manufacturing companies.
“If your requirement is “an external auditor gets strictly read-only access and can trace a reported emissions number all the way back to the underlying invoice/source evidence,” I’d shortlist Persefoni first, with Watershed as another strong enterprise option.”
“For a manufacturing company, I’d shortlist Watershed, Persefoni, Normative, Greenly, and Sphera—but the best choice depends heavily on whether you need corporate carbon accounting, product carbon footprints/LCA, or both.”
The answers call Persefoni and Watershed even for specialized carbon management and emissions measurement.
A few answers separate them by pointing to Watershed specifically for reduction planning and decarbonization programs.
