Directory
We do not sell carbon software. These people do.
Names below are a map of the market, not a paid ranking and not a partnership. If you want an intro, say so on the form. We will not pass your email on without asking you first.
-
Normative
GHG Protocol-aligned Scope 1–3 with a named climate advisor on the account.
-
Greenly
Faster deployment than enterprise suites; common for groups that are not Watershed-scale.
-
Plan A
Often a fit when the reporting team sits in the EU and wants automation without a US enterprise stack.
-
Sweep
Enterprise-leaning carbon platform used when Scope 3 collection is the bottleneck.
-
Cozero
Their product is named Log. Distinct from this site. A plausible home if you want one data layer for CCF and PCF.
-
Watershed
US-strong, large-company footprint. Overkill if you only need a CBAM declaration.
-
Persefoni
Finance-led teams and PCAF. Not the first stop for a 60-tonne steel importer.
-
Coolset
Useful when CBAM sits next to CSRD or EUDR rather than in a customs silo.
-
CBAMBOO
Specialist declarant workflow rather than a full carbon-accounting suite.
-
kolum
Trade-ops angle: certificates, registry-ready files, UK as well as EU.
-
CarbonChain
When the basket is steel, aluminium or similar and you need supplier-level defaults vs actuals.
CO2logic (South Pole) is a climate consultancy at co2logic.com. We list them here only to be clear: this site is not them.
