Why Software Is Now Core to Climate Compliance

SB 253 isn’t just a regulatory checkbox. It’s a systemic shift in how large corporations collect, verify, and report greenhouse gas (GHG) emissions. The law mandates public disclosures of Scope 1, 2, and eventually Scope 3 emissions, validated by independent third-party assurance. This requires more than spreadsheets and siloed teams — it demands software that can centralize data, maintain an audit trail, and ensure readiness for regulatory scrutiny.

In this post, we break down the key software capabilities needed for SB 253, common challenges in implementation, and how Sprih offers a purpose-built solution designed for sustainability leaders navigating complex compliance landscapes.

1. What SB 253 Requires from a Systems Perspective

To comply with SB 253, companies must:

Measure Scope 1 and Scope 2 emissions starting 2026 (based on 2025 data)
Include Scope 3 emissions disclosures by 2027
Publish annual reports to a digital, searchable platform
Undergo limited assurance, and eventually reasonable assurance

Implications for software:

Centralized data ingestion across energy, travel, freight, and suppliers
Emission factor application consistent with GHG Protocol
Version control and audit history of reported data
Export-ready reports aligned with regulatory formatting
Real-time tracking of gaps, anomalies, and incomplete supplier data

2. Why Traditional Tools Fall Short

Many sustainability teams still rely on spreadsheets, PDF-based reporting, or fragmented tools bolted onto ERP systems. These setups:

Can’t handle the dynamic complexity of Scope 3 supply chains
Lack audit trails and data lineage
Fail to provide real-time insights or assurance readiness
Require manual consolidation and duplicate effort

Software purpose-built for climate compliance solves for accuracy, efficiency, and accountability at scale.

3. Core Software Capabilities for SB 253 Compliance

Here’s what a sustainability platform needs to do — out of the box:

A. Automated Emissions Data Collection

Integration with telemetry, energy systems, travel data, logistics platforms
OCR for PDF bills and utility data
APIs for vendor and fleet data

B. Emission Factor Management

Use of EPA, DEFRA, and other approved databases
Application based on activity type, geography, and year
Transparent factor sources for assurance purposes

C. Scope 3 Supplier Engagement Tools

Multi-lingual supplier portals
Custom data-sharing options: direct input or public data proxy
Role-based access and validations

D. Audit Readiness

Immutable logs and timestamps
Auto-generated audit trails for each disclosure
Version comparisons with comments and flags

E. Reporting & Compliance Alignment

Automated templates for SB 253 formats
Parallel alignment with CSRD, BRSR, CDP
Peer benchmarking modules
