Independent directory
Find the right questions before you find a vendor.
SB253 Vendors is an editorial research project mapping the companies and consultancies that work across GHG accounting, emissions data, climate reporting, assurance and related services.
The directory is in progress. It is independent of California, CARB, every regulator and every vendor listed here. A listing is not an endorsement or promise of a particular outcome.
How the directory works
A useful index starts with visible limits.
There are no paid placements. The pages in the directory describe the standards the directory will use as research is added.
01
Define the work
Group services by the work they describe, not by a claim that a provider guarantees an outcome.
02
Show the evidence
Material facts will carry a source and a last-reviewed date so readers can inspect the basis for a listing.
03
Keep the status clear
Corrections, missing information and editorial decisions will be visible rather than filled with invented certainty.
