2027 SB 253 Scope 3 Reporting
5 Clicks or One Prompt, Never a Manual Rebuild
The upstream emissions of your purchased natural gas are the one Scope 3 line you can't pull off a utility bill — and the usual way to get it is rebuilding delivery data by hand, site by site. GasTrace gives you the number straight from the delivery location — click through it yourself, or let your AI agent pull it over our MCP.
The Gas Line Is the One You Rebuild by Hand
The gas you burn on-site is your Scope 1 — straightforward, and not the problem. The emissions from getting that gas to you — extraction, processing, pipeline transport — are Scope 3 Category 3, and they're invisible from the meter.
Without a tool, you reconstruct them: pull delivery locations and volumes for every facility, match each to an emission factor, document the trail. For one site, tedious. For a few hundred, it's a project with a deadline attached.
Three Ways in, Scaled to How Much You've Got
One location — enter the delivery point, get the report. Five clicks.
Many locations — feed your list and get them back as a set.
Zero-touch — connect GasTrace to your AI assistant over MCP and have it pull the numbers for you. You don't open the tool; your agent does.
That's the whole pitch: whatever the footprint, getting the number is easier than rebuilding it.

The Number Comes with Its Own Defense
A spreadsheet number can comply — but you're the one who has to defend it: document the method, hold the trail, explain to the verifier where the factor came from and how you drew the Category 3 boundary. GasTrace hands you the number with the defense already attached — the underlying record, the methodology, and the verification carried alongside it, so you hand over a record instead of reconstructing your reasoning on demand.
The verification standard is ISO 14064-3. Because the number follows your actual gas rather than a national blend, it's truer to your operations than an industry-average factor —which matters when the same figure feeds your reduction targets and investor reporting, not just the CARB filing.
2027 sounds far. This year's data isn't.
SB 253 reports cover the prior fiscal year, so your 2027 Scope 3 filing most likely covers the gas you're burning right now. Capture it as it accrues and it's cheap and calm. Wait, and you're reconstructing a year of multi-site delivery data against the clock.
Scope 1 and 2 reporting comes first, due in 2026; Scope 3 begins in 2027 — and the exact 2027 shape is still in CARB's rulemaking, with the program also under a pending legal challenge, so no one can hand you a fixed gas-Scope-3 date. A limited-penalty window for good-faith Scope 3 disclosures runs from 2027 through 2030 — that's room to get ahead, not a reason to sit on it.
For Companies with a Real Gas Footprint
Manufacturing, data centers, campuses, logistics, food production, multi-site retail — anywhere the gas line is large and spread across locations, and a generic factor stands out under review.
Built for the sustainability, compliance, and procurement teams who own the number, and the ESG platforms and consultants reporting on their behalf. Whichever side you sit on, you're the one who has to stand behind the gas figure.
FAQ
No. Scope 1 and 2 come first, in 2026; Scope 3 begins in 2027, with the exact timing still in CARB rulemaking. This is about having the gas number in hand — easily — before then.
