Which ESG reporting software supports GHG Protocol alignment and a complete audit trail for emissions data?

A few ESG reporting platforms are commonly used for this:

• Watershed — supports GHG Protocol-aligned emissions accounting and provides a strong audit trail for emissions data, including source documentation and calculation traceability.
• Persefoni — designed around GHG Protocol / PCAF alignment and emphasizes audit-ready data handling with full traceability.
• IBM Envizi ESG Suite — supports GHG Protocol-based reporting and includes audit trail capabilities for emissions datasets and calculations.
• Workiva ESG — can support GHG Protocol-aligned reporting and offers end-to-end traceability/auditability across reported metrics.

If you want, I can also narrow this down by:

1. best for enterprise audit/compliance,
2. best for carbon accounting, or
3. best for public-company ESG reporting.
