THE INSTRUMENT · FLAGSHIP PILLAR
A Carbon Inventory Certificate (CIC) is a verified digital record of primary-data environmental performance tied to a physical commodity. It moves downstream with the goods and settles in a buyer’s Scope 3, Category 1 inventory as an audited reduction — not compensation for emissions elsewhere.

01 The Lifecycle
Every state change is recorded once, in one place. A certificate cannot be in two inventories at once.
01
Issue
Verified performance at origin becomes a certificate with a unique ID.
02
Transfer
Custody passes downstream as the commodity changes hands.
03
Transform
Mass balance carries performance across processing into the byproduct.
04
Settle
The buyer takes final custody against a specific purchase.
05
Retire
The claim lands in Scope 3, Cat 1. The certificate is spent — permanently.
02 Beyond the farm gate
A CIC begins with primary performance at origin — but a product’s footprint doesn’t stop at the farm gate. The same rail can layer additional emissions data — packaging, energy, transportation — onto the certificate, so it reflects a fuller cradle-to-gate intensity without losing its audit trail.

Per-layer provenance
Every layer shows its source
Packaging, energy, and transportation each carry their own method, version, and boundary — so an auditor can see what every part of the number covers.
No blending away rigor
Layers stay legible
The certificate records which layers are included and never fuses them into one opaque figure — you can always decompose it back to the source.
Still single-use
One lifecycle, richer content
Layering adds detail, not claims. The certificate is still issued, cleared, and retired exactly once against a specific purchase.

Frequently asked
What is a Carbon Inventory Certificate?
-
A verified digital record of primary-data environmental performance tied to a physical commodity. It moves with the goods via mass balance and lands in a buyer's Scope 3, Category 1 inventory as an audited reduction.
How is a CIC different from a carbon offset?
-
A CIC represents inventory-linked performance measured at the source and stays attached to the commodity. An offset compensates for emissions occurring elsewhere and is detached from the goods purchased.
I want to switch from carbon offsets to real reductions. How?
-
Attach a CIC to a commodity you already purchase. Nset maps the supply shed, issues against verified Tier 3 performance, and the reduction settles in your Scope 3, Category 1 inventory this cycle.
Can a certificate be double-counted?
-
No. Every certificate has one ID and one lifecycle in the registry. Once retired against a claim it is spent and cannot re-enter another inventory.
Can a certificate include emissions beyond the farm?
-
Yes. A CIC starts with primary performance at origin, but the same canonical schema can layer packaging, energy, and transportation data onto the certificate, so it reflects a fuller cradle-to-gate intensity rather than origin alone.
How is layered emissions data kept auditable?
-
Each layer enters through the same MRV-agnostic ingestion and carries its own provenance — source, method, version, and boundary. The certificate records which layers are included, so an auditor can see exactly what the intensity figure covers.
