SB 253 deadline: November 10, 2026

Most emissions consultants clean data by hand. We use AI.

Modus Group helps California companies subject to SB 253 turn messy activity and utility data into a compliant Scope 1 & 2 filing — faster than a traditional consultancy, without cutting corners.

Scope 1 & 2 filing deadline, 2026

CA-only

We work exclusively with California-jurisdiction clients

CARB pushed the first-year Scope 1 & 2 deadline from August 10 to November 10, 2026 — a procedural extension, not a substantive change. Most companies haven't restarted their vendor search yet. We have.
