The carbon market has tied itself in knots over a question it has answered wrongly: do voluntary carbon-neutral claims need corresponding adjustments? The confident answer doing the rounds — “yes, or it’s greenwashing” — rests on collapsing two different things into one. Carbon neutral is not net zero. Hold them apart, and the corresponding-adjustment question answers itself — while a great deal of high-quality climate action stops being needlessly blocked. This is Carbon Advisory’s position, and it is deliberately direct.
Almost every error in this debate starts by treating net zero and carbon neutrality as the same claim. They are not. One is where the whole economy must arrive; the other is how a responsible organisation gets there.
Unabated emissions reduced as far as is technically and economically possible — down to irreducible residuals — and those residuals offset with long-term, stable removal credits: carbon physically taken out of the atmosphere and durably stored. An end-state. The organisation’s net contribution to atmospheric carbon is nil. Where everyone needs to be by ~2050.
The journey toward that destination. Each year, reduce along a science-based trajectory and balance still-unabated emissions with carbon credits — reductions first, shifting toward removals as the journey proceeds. It does not claim the residual has been finally cancelled. This is exactly what ISO 14068-1 governs.
Trying to make “carbon neutral” mean “net zero” is the original error. One is a destination; the other a pathway. Demand that the pathway meet the conditions of the destination — uniquely-claimed removals, corresponding adjustments — and you abolish the mechanism that funds the journey. Keep them distinct, and everything else falls into place.
The demand for CAs on voluntary claims runs straight into a wall: the instrument barely exists. A corresponding adjustment needs a host-country Letter of Authorization — the government adding exported tonnes back onto its own national ledger. As of mid-2026:
This is not a backlog that will clear — it is a rational sovereign strategy. Authorising an export means giving up cheap reductions toward your own NDC and buying expensive ones at home, so countries keep the low-hanging fruit and export almost nothing. India has published a priority list (green hydrogen, CCUS, offshore wind, SAF) that deliberately excludes standard solar, wind and forestry; China is absorbing its cheap reductions into its own ETS.
What little authorised supply exists is absorbed by mandatory compliance demand — CORSIA, NDC-acquiring governments — and priced at a premium for its sovereign-guaranteed exclusivity. So insisting on a CA for a voluntary claim today demands an instrument the largest suppliers have chosen not to produce, that compliance buyers are hoovering up, at a premium — to solve a problem the voluntary buyer doesn’t have. The effect isn’t higher integrity. It’s stalled climate action.
Most confusion comes from treating “double counting” as a single thing. It is an umbrella for three mechanically distinct problems — and a corresponding adjustment touches only the third.
| Limb | The problem | Where it’s solved |
|---|---|---|
| Double issuance | Two credits for the same physical tonne | Crediting programme (ISO 14068-1 §11.3(h)) — closed |
| Double use / retirement | The same credit retired or used twice (ISO calls this “double counting”; ICVCM calls it “double use”) | Registry — unique serials, retirement in the entity’s name (§11.4) — closed |
| Double claiming | The same reduction counted by two parties toward their targets | The Paris–voluntary intersection — what a CA addresses |
A corresponding adjustment touches only the third limb — and only part of it. It says nothing about additionality, permanence, or safeguards. For a non-CA carbon-neutral claim, the first two limbs are closed by the programme and the registry. The third splits in two:
Country ↔ country double claiming — cannot arise. A CA is the mechanism that moves a tonne between national ledgers. With no CA, the tonne never leaves the host’s NDC — so no second country can claim it. Not applying a CA doesn’t cause country-to-country double claiming; it is precisely what prevents it.
Entity ↔ host-country-NDC — the only thing left. This — not country-to-country — is the single residual. And even it is more theoretical than real.
This is the point most commentary misses, and it is the strongest argument here. Follow where the tonnes are actually counted.
The organisation’s GHG Protocol / ISO 14064-1 footprint reports all of its emissions — every tonne of fossil fuel it burned. The carbon credit it buys does not reduce that footprint. It still reports its gross emissions in full.
The host country’s NDC inventory is compiled top-down from national energy statistics. It counts the country’s physical emissions and reductions, gross.
The carbon-neutral claim is a communications and accountability layer that sits alongside the carbon accounts, not inside them. So the entity↔NDC “overlap” is not a double entry anywhere. Both ledgers stay complete and gross. The overlap exists only as a notional question — could the same physical reduction be spoken about by two parties? — and the honest response is to disclose it, not to buy a corresponding adjustment to “fix” an accounting error that was never made.
For most voluntary project types it doesn’t even arise notionally: distributed, community-scale activities — off-grid solar, clean cookstoves, community biogas — sit below the resolution of national inventories, so the host’s NDC never registers them at all.
Where a project is large enough to show in national statistics, the overlap is notional and immaterial, because the credit is additional: the host’s NDC baseline assumed the project didn’t exist, so the tonne is genuinely incremental — it can’t inflate the global total however many parties report it. No one’s trajectory to zero is slowed or falsified; the credit simply accelerates real-world action.
Because the overlap is theoretical rather than hidden, the right move is to state the basis of the claim openly — on packaging, the website, the email footer:
This ties the claim to the standard, signals that neutrality was achieved by financing mitigation beyond the organisation’s boundary (not by reducing the reported footprint), and makes plain that the credits sit alongside the footprint and carry no corresponding adjustment. The accompanying ISO 14068-1 report states the same explicitly (§12(t)). Transparency isn’t a weakness of this position — it is the position. A claim that openly declares its own basis is far stronger than a “net zero” cancellation an organisation can’t actually support.
Net zero can only be reached with long-term removal credits. Zero means zero. You are not at zero while the carbon you emitted is still in the atmosphere, just because someone else avoided emitting elsewhere. Burning fossil fuels to emit ten tonnes and then financing the avoidance of ten tonnes somewhere else does not return you to zero — your ten tonnes are still up there. Only the durable removal and storage of an equivalent ten tonnes does. For an end-state claim, reductions are not equivalent to removals.
Carbon neutrality can use reduction credits precisely because it is a pathway claim, not an end-state. Balancing unabated emissions with high-quality reduction credits — while driving down your own emissions on a science-based trajectory — is a legitimate, finance-mobilising stepping stone.
And the two converge. As the world approaches net zero, reduction opportunities get used up — claimed by countries meeting NDCs and companies meeting science-based targets — until removals are the only credit type left. The credit mix shifts from reductions to removals as the journey proceeds, and at the destination only removals remain. That’s not a coincidence; it’s the mechanism by which the neutral pathway lands on the net-zero destination.
The carbon-neutral claim earns its keep by distinguishing genuine leadership from box-ticking.
Has published a science-based target. But the transition plan is thin, the reductions aren’t really happening, and it takes no action beyond its own value chain. In substance, it has declared an intention and done very little.
Has a science-based target, a robust transition plan reviewed against ISO 14068-1, and a footprint independently verified under ISO 14064-3 — and, having genuinely reduced in line with that plan, has gone above and beyond by financing beyond-value-chain mitigation to balance its remaining unabated emissions.
These two are on different planets. The carbon-neutral claim exists to recognise the second — “carbon neutral now, in line with ISO 14068-1 via BVCM; net zero by [year].” Penalising it — by demanding a corresponding adjustment its claim doesn’t need, or by collapsing its honest stepping-stone claim into a net-zero test it never claimed to meet — discourages exactly the behaviour the climate needs most. It should be encouraged at every opportunity.
We help organisations reduce on a science-based trajectory, balance their unabated emissions with high-quality credits, and make a carbon-neutral claim that discloses its own basis and survives scrutiny. The 30-minute discovery call is the starting point.
