Our take
Where Greenstone leads
- Stronger evidenced coverage on 8 of the 26 capabilities where they differ (led by emission factor library and water, waste & energy tracking).
Where Persefoni leads
- Stronger evidenced coverage on 18 of the 26 capabilities where they differ (led by calculation audit trail and financed / portfolio emissions).
Where they differ
The 26 capabilities (of 59 in the ESG & sustainability taxonomy) where the evidence separates them, biggest gaps first. “Not evidenced” means our research found no public documentation of this capability — the vendor may still offer it. Confirm on a demo.
