Sweep is the sustainability intelligence platform that lets you collect, calculate, and report your emissions with minimal setup.
Connect your data once. Let Sweep handle the calculations and structure.
Simple workflows that don’t require ESG experts.
One dedicated expert supports you through the audit process.
Why most teams struggle with SB 253 reporting
SB 253 requires assured climate disclosures, including Scope 3, but data rarely lives in one place. Manual reporting increases cost, effort, and risk.
Sweep makes it much easier to achieve compliance, and really streamlines what is a complex audit process.
Never fail an SB 253 audit
With Sweep, you’ll have audit-ready emissions data, with built-in checks and expert support.
Sweep’s structured data trails reduce preparation time and assurance fees.
