California Climate Disclosure Supplier Data Infrastructure
California climate disclosure requirements increase the need for controlled Scope 1, 2 and 3 source data, especially supplier and value-chain information. Emissa can connect the supplier evidence layer to the organization’s reporting process.
CARB program development
CARB is developing the corporate greenhouse-gas reporting program authorized by SB 253 and the climate-related financial-risk disclosure program authorized by SB 261, as amended by SB 219.
Supplier data matters for Scope 3
CARB describes SB 253 as requiring covered reporting entities to disclose Scope 1, 2 and 3 greenhouse-gas emissions. Supplier, purchasing, logistics and product data therefore become part of the reporting evidence architecture.
Preserve methodology and source records
A defensible process should keep reporting-period data, calculation methodology, source-system references, supplier-specific inputs, assumptions, approvals and version history together.
Emissa operating model
Emissa can structure supplier and purchasing evidence used in Scope 3 workflows while connecting that same data to buyer requests, product footprints and other supplier compliance requirements.
Verify requirements against current official guidance.
Regulatory requirements change. Emissa uses these sources as reference points for workflow design; organizations should confirm current applicability and obligations before relying on a compliance decision.

Frequently asked questions
What California programs are covered here?
CARB identifies SB 253 corporate GHG reporting and SB 261 climate-related financial-risk disclosure programs, as amended by SB 219.
Why is supplier data important?
Scope 3 reporting can depend heavily on value-chain, purchasing and supplier information.
Does Emissa replace CARB reporting systems or assurance providers?
No. Emissa supports source-data and evidence workflow around the organization’s reporting process.
