Verdict
Persefoni is the pick when carbon accounting must withstand audit because it applies GHG Protocol methodology with financial-grade controls and lineage on every emissions figure.
What customers praise
Rigorous emissions methodology, controls and audit trails, and strong TCFD and ISSB alignment suit finance-led sustainability teams.
What customers criticise
It is carbon-centric, so full social and governance disclosure needs complementary tooling, and depth adds onboarding time.
Best for
Finance and sustainability teams that want GHG Protocol carbon accounting with the rigor and controls of a financial system.
