Carbon software splits into marketplace and accounting
Paul Gambill, CEO of Nori, on tokenized projects for social good
This split shows that carbon software is breaking into separate layers, one layer that measures emissions, and another that sources and retires credits. Nori and Patch both sit on the transaction layer, helping companies or apps buy carbon removal and plug it into an existing product flow. Persefoni sits earlier in the workflow, where a company gathers activity data, calculates its footprint, and decides how much carbon still needs to be addressed.

Nori describes itself as a carbon removal payments and price discovery company. It pays suppliers through sales of Nori Carbon Removal Tonnes, takes a 15% transaction fee, and uses its token to let buyers or suppliers lock in a future carbon price. That puts it in the same budget line as Patch, which also intermediates carbon credit purchases.
-
Patch is built as an API first marketplace that aggregates many project developers, standardizes project data, and lets customers buy portfolios of credits without negotiating with each supplier. That is direct overlap with Nori’s goal of being embedded in other products as the backend for carbon removal purchases.
-
Persefoni is carbon accounting software, closer to an ERP for emissions. Its job is to collect fuel, electricity, supply chain, and travel data, convert that into a company footprint, and support reporting. Both Persefoni and Patch explicitly frame offset procurement as a partner function, which is why Nori can fit behind an accounting product rather than compete with it.
The market is moving toward a climate stack where accounting becomes a system of record, and procurement becomes an embedded service. If that structure holds, the winning carbon marketplaces will be the ones that plug into CFO workflows, accounting platforms, and consumer apps, not just the ones with the best standalone dashboard.
