California SB 253 raises the bar for climate disclosure. If your organisation does business in California and falls within scope, you need reliable Scope 1, 2 and 3 data, a defensible reporting process and confidence in your public disclosure. We help clients turn the legislation into a practical programme of work.
The legislation targets organisations with significant revenues and requires annual greenhouse gas disclosure. For many businesses, the real challenge is not the headline requirement — it is building the data, governance and assurance-ready workflow behind it.
Bring operational emissions, energy data and organisational boundaries into one consistent reporting approach that stands up to internal and external scrutiny.
Map value-chain emissions, prioritise material categories and build a supplier data plan that moves you beyond rough estimates.
Create an evidence trail, clear methodologies and stronger controls so disclosures are credible, reviewable and ready for assurance requirements.
We help you define scope, collect the right data and build a reporting process that is efficient enough to repeat year after year.
We assess applicability, reporting boundaries, current data maturity and the practical gaps between your current state and SB 253 readiness.
Using Sustrax and our Carbon Data Intelligence platform, CaDI, we help organise activity data, apply robust emissions factors and improve auditability.
From management information to public-facing disclosures, we help shape the reporting pack, supporting narrative and internal review process.
Our approach is designed to make SB 253 manageable across finance, sustainability, procurement and operations teams.
Identify in-scope entities, boundaries, owners and reporting expectations.
Capture activity data, define calculation logic and align supporting evidence.
Improve review points, methodology notes and assurance readiness across the workflow.
Prepare annual disclosures supported by clear documentation and repeatable processes.
We combine consultancy, software and verification capability so your compliance work is not fragmented across multiple providers.
