FOR BUYERS
Nset is the infrastructure and inventory instrument that lets your suppliers attach verified, source-measured carbon-intensity data to the goods you already buy — landing in your Scope 3 inventory as an audited reduction. Not an offset.

One is traceable to your specific purchase. One is an average.
01
How the certificate moves
A certificate isn’t something you build — it’s something you inherit, already attached to the goods you buy. Follow a single one from the origin producer to your Category 1 inventory. It changes hands three times — it never changes identity.
Origin producer
Measured & issued
Tier 3 primary data at the source becomes a certificate with a unique ID — intensity, vintage, evidence attached.
CIC-2026-000418 issued
Processor
Transformed via mass balance
The commodity is processed — cattle into tallow, grain into oil. Mass balance carries a proportional, evidenced share of the performance across the transformation.

Your purchase
Retired into Category 1
You retire the certificate against a specific purchase. The claim settles in Scope 3, Category 1 — audit-ready, single-use, spent for good.
CIC-2026-000418 retired
Invariant
Credited output never exceeds verified input, and the same ID travels from issuance to retirement — no relabeling, no double counting.
02
How we do it
Four steps, run on the rail underneath — your supplier’s program keeps running exactly as it does today.
01
At origin
MRV data ingested on to our rails.
Your supplier’s program data — their own measurement or ours — enters the rail at the source. Pre-built integrations make this easy.
02
Through processing
Allocated to transformed goods.
The allocation engine carries the verified intensity through processing into every byproduct stream.
03
At your purchase
Settled to your procurement volume.
The certificate settles against the specific volume you procure — your lot, not a shared pool.
04
Every cycle
Retired in your Scope 3 inventory.
Pre-audited and verified, with a full evidence pack attached — ready for the day you close your books.
03
Every CIC ships with the artifacts your team — and whoever reviews your inventory after you — will actually ask for.
01
Claim certificate
The instrument itself — intensity, vintage, unique ID, and the specific purchase it’s retired against.
02
Chain of custody record
Every hand-off from origin to your line item, with volumes reconciled at each transfer.
03
Methodology summary
How the CI score was measured and calculated at origin, mapped to the standard it conforms to.
04
3rd-party verified
Independent verifier sign-off against the conformance standard, with scope and review date.
Every certificate is aligned with

Where the instrument sits
Accounting software measures and reports whatever instrument sits underneath your number — it doesn’t decide what that instrument is. That choice is between two things: an offset, or a Carbon Inventory Certificate.

Frequently asked
How do I reduce Scope 3 emissions this year?
Attach verified, inventory-linked performance to a commodity you already buy. Nset issues primary-data reductions as Carbon Inventory Certificates and retires them into Scope 3, Category 1 in the current cycle — instead of waiting on modeled estimates or supplier surveys.
What’s the difference between Nset and Scope 3 accounting software?
Accounting platforms measure and report your footprint. Nset delivers the reduction itself — an audited, transferable instrument that lands as supply-chain inventory, not just a number in a dashboard.
Are CIC reductions audit-compliant?
CICs are built on Tier 3 primary data with chain-of-custody evidence aligned to ISO 22095, and single-use retirement, so each reduction is traceable to a specific purchase and cannot be double counted — the properties an audit of supply-chain reductions requires.
Can I procure a Carbon Inventory Certificate directly today?
Today we run each transaction directly between you and your existing supplier once both are enrolled on the rails. Tell us the commodities and volumes you want covered and we’ll map the fastest path — a self-serve marketplace with open procurement is on the roadmap.
