California SB 253 — First Scope 1 & 2 reporting deadline: August 10, 2026  ·  119 days remaining
Emissions Compliance Automation

Stop estimating your fleet emissions.
Start measuring them.

The only compliance platform that derives actual CO₂ and NOx values from per-engine exhaust gas measurement — not EPA estimates multiplied by gallons purchased. Disclosure-ready reports delivered to your inbox.

The Problem

Everyone else estimates.
We measure.

How everyone else reports
Purchase fuel
Collect invoices and fuel card receipts across all sites.
Multiply by EPA factor
Total gallons × 10.21 kg CO₂/gallon. Same number regardless of engine condition.
Submit estimate
File a number that treats a well-tuned engine and a failing engine identically.
Output → Estimated emissions

How ScopedCarbon reports
Measure O₂ per engine
In-situ oxygen sensors in each exhaust stack. Continuous. Autonomous.
Derive CO₂ via carbon balance
Patented methodology converts oxygen depletion to actual CO₂ concentration per engine.
Deliver compliance report
Jurisdiction-specific disclosure format. Audit trail from sensor to filing.
Output → Measured emissions
How It Works

From exhaust stack to
compliance stack.

01
Measure
In-situ O₂ and NOx sensors on your engines feed continuous exhaust data through our universal telematic connector. CO₂ is derived per engine using our patented carbon balance methodology.
02
Aggregate
Per-engine values roll up automatically across your organizational hierarchy — engines, assets, sites, business units, legal entities — for any reporting period.
03
Report
Disclosure-ready compliance reports generated for every applicable jurisdiction. SB 253, SEC, EU CSRD, CDP, GHG Protocol — from a single measurement source. Delivered to your inbox.
Supported Frameworks
