Methodology

One mass-balance methodology, aligned with the GHG Protocol LSRS

Segmos runs chains of custody for low-carbon materials.

It reconciles the volumes that carry a climate attribute with the volumes that leave your sites, and records which customer received what. The method follows one catch-all standard, ISO 22095-2 for mass balance, and adds the conditions the GHG Protocol Land Sector and Removals Standard sets for physical traceability.

GHG Protocol LSRS 2026: the bar for climate claims

The Land Sector and Removals Standard (LSRS) is the GHG Protocol's rulebook for land-based emissions and CO₂ removals. Published in January 2026 and effective from January 2027, it tells companies how to count land emissions, land use change and removals in their Scope 3 inventory.

Among its rules, it sets what counts as physical traceability for farm and region-specific emission factors: without it, a company falls back to regional averages and cannot claim the reductions its suppliers achieved.
The tool below tells you whether your set-up clears that bar.

How Segmos helps you keep your mass balance clean and auditable

Every low-carbon volume accounted for, once

Each tonne of low-carbon input you receive becomes credits in a dedicated account. Inventory is created when material arrives, spent when you sell low-carbon product, and can never be counted twice. Your balance cannot go negative, so you can never sell more than you received.

Your rules, applied to every transaction

You define the boundary, the balancing period and the conversion factors once. Segmos applies them to every delivery, every recipe and every sale, and stops a claim before it breaks a rule, instead having your auditor or client discover it after the facts.

Co-products split fairly, partners rewarded

When one process yields several products, the low-carbon attribute follows the real yields, as the GHG Protocol requires. For a given product, you choose which partners receive the low-carbon volumes and the better footprint that comes with them.

A system you can hand to your auditor

Segmos manages your mass-balance system for you: boundary, physical presence, physical link, period, method. No interpretation, no spreadsheet, and it stays true as your operations change.

Carry-forward without loopholes

Unused credits can roll into the next period, but they keep the emission value they entered with and receive an expiry date. Process improvements benefit new volumes, never old stock.

Audit-ready at every period close

Claims are written once and never edited; corrections are new entries. At the end of each period the whole chain of custody can be exported for compliance and auditability.
