Carbon stack splitting into layers
Ryan Miller, VP & GM of Private Markets at Persefoni, on building an ERP for carbon
This points to a carbon stack that is splitting into specialist layers, not collapsing into one winner. EcoVadis helps a large buyer collect broad ESG data from thousands of suppliers, while Persefoni turns emissions data into auditable Scope 1, 2, and 3 carbon footprints and disclosure outputs. In practice, a company can use EcoVadis to push suppliers for sustainability information, then use Persefoni to calculate, report, and manage the carbon piece with finance grade workflows.

EcoVadis is built around supplier engagement and procurement workflows. Its ratings are used by over 1,400 multinational procurement teams, and its index covers tens of thousands of annual ratings across environment, labor, ethics, and sustainable procurement. That makes it a system for gathering and benchmarking supplier ESG data at scale, not a dedicated carbon ledger.

Persefoni is built around carbon accounting mechanics. Its product centers on Scope 1, 2, and 3 measurement, disclosure, financed emissions, auditability, and supplier engagement for emissions data. That is why it fits beside broader ESG systems like EcoVadis and Novata, as the carbon engine inside a wider reporting workflow.

The same pattern shows up downstream with offsets. Sylvera rates the quality and risk of carbon credit projects, and Patch describes carbon accounting providers, credit marketplaces, and ratings firms like Sylvera as separate pieces of the same workflow. First measure emissions, then reduce them, then evaluate and buy offsets for the remainder.
The market is moving toward connected climate systems, where procurement platforms gather supplier evidence, carbon platforms calculate footprints, and offset intelligence firms rate the credits buyers may eventually use. Companies that own one layer well can become the default partner for adjacent layers, which gives Persefoni room to embed itself as the accounting core inside broader ESG and net zero workflows.
