Carbon Credit Readiness

Could any of these savings become carbon credits, and what is missing? NEXUS ZERO screens its evidence and shows where independent certification takes over.

SAMPLE DATA MODE

Sample data. Screening only. Not a certification or eligibility decision. Only an accredited independent body and a registry can decide whether a credit is issued.

From a saving to a credit

A measured saving is not a carbon credit. A credit exists only after an independent body has verified the reduction and a registry has issued it. NEXUS ZERO covers the first steps and stops where certification begins.

NEXUS ZERO does not certify, issue, buy, sell, transfer or retire carbon credits, and it is not a trading platform.

Screening the closed ledger records

Each internally verified sample record is checked against the first questions a carbon-credit programme would ask. Most savings do not become credits, and this screen shows why.

4.71 tCO₂e
Evidence ready, not assessed
WhyHide
A direct reduction with complete internal evidence, but additionality is likely to be questioned. It has not been assessed by any certifier.
- Is there a carbon figure to assess?
  Yes
  Yes. 4.71 tCO₂e, calculated from the sample quantity and a referenced factor.
- Does the reduction happen at a source the organisation owns?
  Yes
  Yes. Less fuel is burned on site, so the reduction is direct.
- Would this have happened anyway? (additionality)
  Concern
  Likely to be questioned. This was a no-cost operational fix that pays for itself, so a certifier may conclude it would have happened without carbon revenue.
- Is the before/after evidence complete?
  Yes
  Yes. Baseline, measured result, evidence source, measurement window and internal review are all recorded.
- Has an accredited independent body verified it?
  Missing
  No. The ledger review is internal. Credits require validation and verification by an accredited independent body, which NEXUS ZERO does not provide.

WhyHide
Evidence is complete, but the reduction is indirect and additionality is open. A certifier would have to judge both.
- Is there a carbon figure to assess?
  Yes
  Yes. 6.78 tCO₂e, calculated from the sample quantity and a referenced factor.
- Does the reduction happen at a source the organisation owns?
  Concern
  No. Saving grid electricity reduces emissions at a power plant the site does not own. Ownership of that reduction can be disputed, and the same reduction could be claimed by others.

  Open question. Capital works can qualify, but a certifier would need an investment analysis showing carbon revenue made the difference.

WhyHide
No carbon figure, so there is nothing a carbon-credit programme could assess.

  No. This is a water saving, and no confirmed water emission factor is available, so no carbon is calculated.

"Internally verified" means the before/after measurement was closed with evidence inside NEXUS ZERO. It is not third-party verification.

What a certifier would still need

None of these steps happen inside NEXUS ZERO. The ledger supplies the measurement evidence they rely on.

01A chosen standard and approved method
The project must follow a published method accepted by the programme, for example under Verra or Gold Standard.
02A defined project boundary and ownership
Which sites and equipment are included, and a clear right to claim the reduction.
03An additionality case
Evidence that the reduction would not have happened without carbon revenue.
04A monitoring plan
How the reduction will keep being measured, and by which meters.
05Independent validation and verification
Carried out by a body accredited for that programme.
06A no-double-claim check
Proof the same reduction is not also claimed through another certificate or by another party.
07A registry account and listing
Credits exist only as entries on a registry, each with a serial number.

What-if value

NEXUS ZERO holds no carbon price data and does not suggest a price. Enter your own assumption to see what the screened tonnes would be worth if every one were certified, issued and sold. That has not happened.

Your assumed price (AED per tCO₂e)Also include the 14.45 tCO₂e that needs external assessmentThese tonnes carry ownership and additionality concerns and may not qualify at all.

Plain-language terms

Carbon credit: A tradable unit for one tonne of CO₂e, issued by a registry after independent verification. A measured saving is not a credit until that happens.
Additionality: The reduction would not have happened without the incentive of carbon revenue. Savings that pay for themselves often fail this test.
Baseline: What emissions would have been without the action. The reduction is measured against it.
Validation and verification: Checks by an accredited independent body: first of the project design, then of the actual reductions.
Issuance: The registry creating credits, each with a unique serial number.
Retirement: Permanently using up a credit so it cannot be sold or claimed again.
Voluntary and compliance markets: Voluntary programmes such as Verra and Gold Standard are opt-in. Compliance schemes are set by law and have their own rules. They are separate systems.
