California Climate Disclosure
Navigating the 2026 Deadlines
The Compliance Gap.
Why Manual Processes Fail the California Test.
California’s third-party assurance requirements make a digital, auditable reporting system essential for SB 253 and SB 261 compliance.
Scope 3 Paralysis
The complexity of tracking value chain (Scope 3) emissions at scale and with auditable rigor is simply too high for manual methods.
Assurance Failure
SB 253's phased assurance (Limited by 2026 → Reasonable by 2030) requires a verifiable, time-stamped audit trail that is impossible to maintain manually.
Financial Risk Disconnect
SB 261 demands you link climate risks (physical and transition) directly to your financial strategy, a dynamic assessment that requires integrated data.
