Our verdict: Persefoni
Best for financial institutions (banks, PE/VC funds, asset managers) needing PCAF-certified tools to measure financed emissions and meet CSRD/SFDR obligations. Not ideal for industrial or commercial SMEs without financial disclosure constraints.
Our verdict: Watershed
Best for large international companies (revenue >€100M) needing to produce verifiable reports for strict investor or regulator requirements. Not ideal for any organization under 500 employees: complexity and cost are disproportionate.
