Carbon neutrality consultancy · UK

Carbon neutral consultants: what they can still deliver

Carbon neutral consultants are still being hired to deliver two standards that have both been withdrawn.

PAS 2060 was withdrawn at the end of 2025, and ISO 14068-1:2023 followed on 11 September 2026, replaced by ISO 14068:2026.

This page sets out what carbon neutrality consultancy can credibly deliver now, what the law asks of a claim, and what to ask a consultant before you hire one.

The work

What carbon neutral consultants do

Carbon neutrality consultancy helps an organisation make a claim about a defined subject and period that it can evidence line by line.

The work starts with a footprint, which a carbon consultancy or emissions compliance consultants would build on the GHG Protocol.

It continues with a reduction plan, a decision about offsetting, and the wording of the claim itself.

A carbon neutral consultant does not certify anything: ISO issues no certificate, and verification is done by a separate verifier.

A claim of this kind is not a net zero target, and the two should never be used interchangeably.

Organisations asking about “carbon compliance consultancy” usually need the reporting regimes as well, which are mapped on the carbon compliance page.

The three stages ISO names

  1. 01
    Quantify

    The carbon footprint of a defined subject — an organisation or a product — for a defined period.

  2. 02
    Reduce

    Reductions and removals within the value chain come first.

  3. 03
    Offset

    Only what remains, with credits chosen and disclosed.

  4. 04
    Demonstrate

    A claim that states its basis, verified by a third party if it is to rest on ISO 14068.

PAS 2060

PAS 2060 consultants: a credential nobody can issue

PAS 2060 was the BSI specification most UK organisations used to demonstrate carbon neutrality.

BSI stopped delivering the scheme from 1 January 2025 and set a period of 24 months from the publication of ISO 14068-1:2023 before the document itself was withdrawn.

The UKAS migration deadline was 31 December 2025, after which PAS 2060 left the accreditation schedule.

The old BSI PAS 2060 page now serves BSI’s ISO 14068-1 verification page.

So a “PAS 2060 consultant” today can help you describe a past declaration accurately, or move to ISO 14068, but cannot deliver a PAS 2060 credential.

The two-part trap

A PAS 2060 opinion issued for a past period stays valid for that period.

It is not a current credential, so never describe it in the present tense — and never claim it was invalidated.

Three dates, three different facts

  1. 1 Jan 2025
    BSI stops delivering the scheme

    No new PAS 2060 verifications are sold or started.

  2. Nov 2025
    The document's withdrawal period ends

    24 months from the November 2023 publication of ISO 14068-1:2023.

  3. 31 Dec 2025
    Last opinions issued

    UKAS removes PAS 2060 from the accreditation schedule.

ISO 14068

ISO 14068-1:2023 is withdrawn — ISO 14068:2026 replaces it

BSI named ISO 14068-1:2023 as PAS 2060’s successor, and most of the market migrated to it during 2025.

ISO’s catalogue record now shows that edition as withdrawn on 11 September 2026, revised by ISO 14068:2026.

The successor drops the part number and the words “Transition to net zero” from its title.

In ISO’s words it covers achieving and demonstrating carbon neutrality “through the quantification, reduction and offsetting of the carbon footprint”.

Reductions and removals within the value chain take priority over offsetting, the standard is programme-neutral, and it is not intended for territories.

ISO gives the new edition’s publication date only as September 2026, so this page gives no day.

A consultant who writes “ISO 14068-1 certified” as a current credential is two steps out of date: ISO certifies nobody, and the 2023 edition is gone.

The law on claims

Lawful in the UK if substantiated; restricted in the EU

No UK instrument targets carbon neutral or offsetting claims specifically.

The Digital Markets, Competition and Consumers Act 2024 prohibits unfair and misleading commercial practices from 6 April 2025, and its Schedule 20 blacklist says nothing about carbon, climate or offsetting.

It replaced the Consumer Protection from Unfair Trading Regulations 2008, which continue only for acts before that date.

The CMA’s Green Claims Code sets six principles, including that claims are truthful, clear and substantiated, and the CMA says it continues to apply in substance.

The ASA applies CAP Code section 11, and its advice on carbon neutral claims says marketers should avoid unqualified claims and give information about any offsetting scheme used.

In the EU, Directive (EU) 2024/825 bans, from 27 September 2026, any claim based on offsetting that a product has a neutral, reduced or positive greenhouse gas impact.

The UK has no equivalent, so a campaign running in both markets needs two answers.

What a carbon offset consultant should check

Our summary of each owner's published rules, as at 30 September 2026. Nothing on this site is a recommendation to buy any credit.
CheckWhy it mattersWhere it is set
Removal or avoidanceA removal takes carbon out of the atmosphere; an avoidance credit claims emissions that did not happen. They are different claims.The credit's methodology
AdditionalityWould the project have gone ahead without credit revenue? ICVCM rejected eight renewable energy methodologies on this ground.ICVCM Core Carbon Principles
Methodology approvalICVCM approval attaches to a methodology and version — 44 were CCP-Approved as at 12 August 2026 — not to one credit's performance.ICVCM assessment status
ProgrammeA programme such as Gold Standard or Verra’s VCS being CCP-Eligible does not make every credit it issues CCP-labelled.ICVCM programme list
VintageThe year the reduction happened should match the period being claimed against.The registry record
What the claim saysVCMI: credits "are not counted as internal emission reductions"; Platinum is not a carbon neutral claim.VCMI Claims Code v3.1

Offsets are never deducted from reported emissions: UK SRS S2 ¶29(a) asks for gross figures, and a net target is disclosed alongside its gross target under ¶36(c).

A company with a net target that reports under UK SRS S2 also describes its planned use of credits under ¶36(e), including the third-party scheme that will verify or certify them.

Independent analysis of credit quality, ratings and the UK rules on carbon credits is on srs.credit, a sister reference in this network.

Choosing a carbon neutral consultant

Questions to ask before you hire

Which standard will the claim rest on — ISO 14068:2026, the withdrawn 2023 edition, or no standard at all?

What exactly is the subject and period of the claim, and what is excluded from the boundary?

Which reductions come first, and how much of the claim will rest on offsetting?

How will credits be chosen, and will you show us the methodology, programme, vintage and retirement record for each?

Who will verify the claim, and are they independent of you?

What wording will you advise for our website and packaging, and what will you advise us not to say?

If we sell into the EU, how will the claim change from 27 September 2026?

Carbon Legal is an independent reference and does not carry out carbon neutrality engagements or verification.

A consultancy service is in development; for now you can book a free 15-minute call or use the contact page, and we can introduce you to independent specialists where that helps.

To see which reporting regimes apply alongside any claim, try the carbon legislation readiness check.

Independence

Ask whether the consultant sells credits, and whether any verifier they suggest is also advising you.

UKAS accredits verification bodies, not consultants, so “UKAS-accredited consultant” is not a thing.

Frequently asked

Questions people ask

What do carbon neutral consultants do?

Carbon neutral consultants help an organisation measure the footprint of a defined subject and period, reduce what it can, decide whether and how to offset the rest, and document a claim that states its basis. They can also prepare for third-party verification against ISO 14068. They cannot issue a certificate themselves: ISO certifies nobody, and verification is done by a separate verifier.

Can I still hire a PAS 2060 consultant?

Not for a current credential. BSI stopped delivering the PAS 2060 scheme from 1 January 2025, UKAS removed it from the accreditation schedule on 31 December 2025, and PAS 2060 was withdrawn at the end of 2025. A consultant offering "PAS 2060 certification" today is offering something nobody can issue. A PAS 2060 declaration for a past period stays valid for that period and should be described in the past tense.

What is ISO 14068 and which version applies now?

ISO 14068 is the international standard for achieving and demonstrating carbon neutrality through quantification, reduction and offsetting, with reductions and removals in the value chain taking priority over offsetting. ISO 14068-1:2023 was withdrawn on 11 September 2026 and is being replaced by ISO 14068:2026, "Climate change management — Carbon neutrality". ISO gives the new edition's publication date only as September 2026.

What is the difference between carbon neutral consultants and net zero consultants?

A carbon neutral claim covers a defined period in which remaining emissions are balanced, usually by offsetting. A net zero target describes deep reductions over years, with only residual emissions neutralised. Carbon neutral consultants focus on the claim and its evidence; net zero consultants on the target and the reduction plan. The ASA treats unqualified versions of either claim as misleading.

Is "carbon neutral" banned in the UK?

No. No UK instrument bans offset-based carbon neutral claims. The Digital Markets, Competition and Consumers Act 2024 prohibits misleading practices from 6 April 2025, and its Schedule 20 blacklist contains nothing about carbon, climate or offsetting. The ASA's settled position is that an unqualified "carbon neutral" claim is misleading, so a claim must set out its basis, including how much rests on offsetting and which scheme is used.

Is "carbon neutral" banned in the EU?

For product-level claims based on offsetting, yes, from 27 September 2026. Directive (EU) 2024/825 adds to the EU list of banned commercial practices any claim, based on offsetting, that a product has a neutral, reduced or positive greenhouse gas impact, and Member States must apply it from that date. It does not apply in the UK.

What should a carbon offset consultant check in a carbon credit?

Whether it represents removal or avoidance, whether additionality is demonstrated, whether its vintage matches the period being claimed against, and whether its methodology is CCP-Approved by the ICVCM. ICVCM approval attaches to a methodology and version, not to a single credit's performance, and a programme being CCP-Eligible does not make every credit it issues CCP-labelled. Nothing on this site is a recommendation to buy any credit.

Can offsets be deducted from our reported emissions?

No. UK SRS S2 paragraph 29(a) asks for absolute gross Scope 1, 2 and 3 emissions, and a company with a net target also discloses its gross target under paragraph 36(c). Credits are reported separately, as a statement about what was purchased, not as a reduction in the inventory.

How much does carbon neutral consultancy or verification cost?

This page gives no price. No consultant or verification body publishes a standard fee for ISO 14068 work, and a characterised market range is not a sourced figure. Ask each provider for a written quote against a defined subject, boundary and period.
