The project should commission a shared, traceable evidence package for the white paper and the venue’s website. It should suspend the carbon-neutral claim until its precise meaning and supporting evidence have been assessed. First, however, it must establish that the proposed issuance and trading route works under both Vietnamese law and the applicable EU token regime.
- Identify the legal issuer, offeror, admission applicant and venue. Their disclosure responsibilities depend on their roles and the token’s classification.
- Measure the relevant consensus mechanism. A project’s office footprint, the venue’s operations and a token-wide environmental claim have different boundaries.
- Use the mandatory indicators and explain estimates. Report gross values without subtracting offsets.
- Give each disclosing entity access to evidence, correction rights and a reliable update service. Buying calculations does not transfer its disclosure responsibility.
- Correct unsupported marketing across all channels and coordinate the white paper with the venue’s separate publication and review duties.
Clear the Vietnamese route and EU classification first
Vietnam’s recognition of digital assets does not itself authorise every issuance or overseas listing. The digital-asset provisions establish categories and government regulation; the proposed issuer, token rights and transaction must still fit the applicable route. (Law No. 71/2025/QH15, Articles 46–48.)
Where the issuance falls within Vietnam’s cryptoasset market pilot, the issuer must be a Vietnamese limited liability or joint-stock company. The token must be based on real underlying assets, excluding securities and fiat currency. It may be offered and issued only to foreign investors. Those issued assets may trade only between foreign investors through a provider licensed by Vietnam’s Ministry of Finance. The pilot also requires transactions and settlement in Vietnamese dong. (Resolution No. 05/2025/NQ-CP, Articles 1–2, 4(7), 5 and 6.)
An EU venue’s MiCA permission alone does not satisfy that Vietnamese provider condition. If the pilot applies, establish a legally permitted trading arrangement before proceeding with admission. If none is available, postpone the proposed listing. The project’s Vietnamese connection alone does not establish that every offshore structure falls within the pilot: incorporation, issuance location, investor access, asset backing and payment flows need examination.
EU classification is a separate exercise. Financial instruments are excluded from MiCA; asset-referenced tokens and e-money tokens have different issuer and admission requirements. Real-asset backing under Vietnamese rules does not automatically make the token an EU asset-referenced token. The ordinary-token route discussed below applies only where those other classifications and exclusions do not apply. (Regulation (EU) 2023/1114, “MiCA”, Articles 2(3)–(4), 3(1)(6)–(7), 16 and 48.)
For token issuers, the first document should therefore record classification, responsible entities, permissions and the permitted trading channel. Environmental disclosure work can proceed alongside that assessment.
Assign the white-paper and venue duties separately
For an ordinary MiCA token, the person seeking EU admission normally draws up, notifies and publishes the white paper. Its sustainability section must address the principal adverse climate and other environmental impacts of the consensus mechanism. An offeror may have parallel obligations where there is also an EU public offer. (MiCA, Articles 4(1), 5(1) and 6(1)(j).)
A platform initiating admission must fulfil the Article 5(1) requirements where a required white paper has not been published. Alternatively, an admission applicant and platform can agree in writing that the platform will perform specified Article 5 duties. That agreement must require the applicant to supply the necessary information. It should identify exactly who prepares, checks, notifies and publishes each document. (MiCA, Article 5(2)–(3).) The applicant remains responsible for incomplete, unfair, unclear or misleading information it supplies under that arrangement. (MiCA, Article 15(3).)
The venue has a further duty as a cryptoasset service provider, or CASP. It must publish, prominently on its website, sustainability information for each cryptoasset for which it provides services. It may obtain information from a white paper, but its own disclosure duty remains. A hyperlink to a white paper does not replace this separate requirement. (MiCA, Article 66(3) and (5); Delegated Regulation (EU) 2025/422, Articles 3 and 5.)
Where the token already trades on another EU platform, a compliant, updated white paper can be used with its responsible person’s written consent. Tokens admitted before 30 December 2024 have a separate white-paper transition, with a 31 December 2027 platform deadline. That transition does not defer the CASP’s website duty. (MiCA, Articles 5(4), 66(5) and 143(2).)
The venue must also apply its admission rules and suitability assessment. A completed sustainability report does not establish that the token otherwise qualifies for admission. (MiCA, Article 76(1)–(2).)
Commission the correct measurements
Regulation 2025/422 supplies the MiCA sustainability indicators, methods and presentation rules. Table 2 of its Annex is mandatory for relevant white papers and CASP website disclosures. It covers the disclosing entity and identifier, cryptoasset, consensus mechanism, incentives and fees, reporting period, annual energy consumption, and sources and methods. (Regulation 2025/422, Articles 4(1), 5(1) and 6(1); Annex, Table 2, S.1–S.9.)
The central metric, S.8, is total energy used to validate transactions and maintain the distributed ledger’s integrity, expressed in kilowatt-hours per calendar year. Commission a documented boundary covering the relevant consensus mechanism and nodes. Do not substitute the issuer’s electricity bill or a favourable allocation to the project’s token for the required ledger measure. (Regulation 2025/422, recital 8; Annex, Table 2, S.8.)
If S.8 exceeds 500,000 kWh a year, the white paper must also include Table 3. For CASPs, that additional requirement applies where the threshold is exceeded and the provider operates a trading platform or exchanges cryptoassets for funds or other cryptoassets. The venue here falls within the trading-platform service category. Exactly 500,000 kWh does not exceed the threshold. (Regulation 2025/422, Articles 4(2) and 5(2).)
Table 3 adds renewable energy share, energy per validated transaction, annual Scope 1 and Scope 2 ledger greenhouse-gas emissions, emissions per validated transaction, and the corresponding sources and methods. Annual emissions use tonnes of CO2 equivalent; transaction intensity uses kilograms. (Regulation 2025/422, Annex, Table 3, S.10–S.16.)
Table 4’s additional indicators, including Scope 3 emissions, waste, water and reduction targets, are optional. Supplementary indicators below the threshold are also optional. Choosing to disclose them brings the corresponding format, methodology and source requirements; voluntary figures cannot be presented without those qualifications. (Regulation 2025/422, Articles 4(2)–(3), 5(2)–(3) and 6; Annex, Table 4.)
Keep the consensus assessment distinct from the project’s business footprint and the CASP’s own operations. Where a token supports physical infrastructure, the hardware and node-reward activities also require separate analysis. A measurement of one layer does not establish the environmental performance of every other layer.
Use estimates transparently
Estimated data is permitted where information is not readily available. The disclosure must identify the estimated indicators and explain the best efforts used to obtain information, the methodology, assumptions, precautionary principles and relevant departures from the prescribed calculation guidance. A vendor’s output therefore needs an accompanying explanation, not merely a score or badge. (Regulation 2025/422, Article 6(7).)
Methods must be rigorous, systematic, objective, capable of validation and applied continuously. Energy and emissions calculations must follow the European Sustainability Reporting Standards (ESRS) calculation guidance incorporated by Article 6(5). Commission an environmental accounting specialist to assess node coverage, equipment and energy assumptions, emissions factors, missing data and uncertainty. Legal review cannot supply those measurements. (Regulation 2025/422, Article 6(5).)
The rules permit reuse of relevant information from another white paper for a cryptoasset using the same consensus mechanism. Identify that white paper’s author and relevant identifier. If a third party verified the information, disclose its name; this conditional requirement does not impose a universal external-audit obligation. Article 6(8) also requires clear identification of omitted information from its listed additional source disclosures. (Regulation 2025/422, Articles 2(2) and 6(2)–(4), (8).)
Offsets must not reduce the reported energy or emissions indicators. Relevant offset mechanisms may be described separately in the sources-and-methodologies section. The calculations remain gross. (Regulation 2025/422, Article 6(6).)
Replace the unsupported carbon-neutral claim
Estimated consensus energy consumption cannot, by itself, substantiate a carbon-neutral token. Energy is not an emissions inventory. An inventory for network validation is not automatically an assessment of the token’s entire lifecycle, the project’s business or the venue’s services. Proof of stake describes a consensus mechanism; its use alone does not prove neutrality.
The project should stop further use of the broad claim while reviewing its website, white paper, social posts, presentations and partner materials. Apply MiCA’s modification and retention procedure to required white papers and related published marketing. (MiCA, Article 12.) Any replacement should state what was measured, for which network and period, using which method, and whether the value is estimated. A narrower factual statement can be used only when the underlying evidence supports it.
MiCA requires white-paper information to be fair, clear and not misleading. Marketing must satisfy the same standard and be consistent with the required white paper; CASPs have their own fair-information obligation. A qualified estimate in one document cannot cure an unqualified neutrality claim elsewhere. (MiCA, Articles 6(2), 7(1)(b)–(c), 14(1)(b) and 66(2).)
Consumer advertising needs a further check in each target Member State. Directive (EU) 2024/825 requires national measures applying from 27 September 2026. Its amendments prohibit claims, based on greenhouse-gas offsets, that a product has a neutral, reduced or positive greenhouse-gas impact. They also address generic environmental claims and claims about an entire product or business based on only one aspect. Check the actual national implementing rules and the claim’s consumer-facing scope; do not assume that explaining offsets makes a prohibited product claim permissible. (Directive 2024/825, Article 4(1) and Annex, point (2), inserting Directive 2005/29/EC, Annex I, points 4a–4c.)
A marketing compliance review should reconcile the proposed words with the evidence and applicable rules. A calculation report is not itself approval of the claim.
Build the evidence and supplier package
Assign four responsibilities in writing. The project supplies the token’s technical architecture, network identifiers and change history. The network operator or available network sources supply relevant operational evidence. The vendor produces the calculations and their provenance. The white-paper responsible person and CASP each review and approve their own disclosures. These are recommended working arrangements supporting the statutory duties, rather than a transfer of those duties to the vendor. (MiCA, Articles 6(2) and 66(2), (5); Regulation 2025/422, Articles 2–6.)
The supplier contract should cover:
- Deliverables: completed indicator fields, reporting boundaries and periods, methods, assumptions, source records, model versions, estimated-field labels and an explanation of missing information.
- Evidence access: sufficient working material to validate the results, including relevant source datasets and calculation records, with lawful access to third-party inputs.
- Use rights: express permission for the project, white-paper responsible person and venue to publish, reproduce, translate, correct and retain the outputs, and provide supporting material to competent authorities.
- Quality and corrections: acceptance criteria tied to the applicable indicators, notification of errors or methodological changes, prompt corrected outputs, and cooperation with independent technical review.
- Continuity: scheduled updates, event-driven recalculation, access after termination and an orderly handover to a replacement provider.
- Commercial remedies: proportionate liability, insurance and recovery terms, without suggesting that contractual risk allocation removes statutory responsibility.
These are proposed contract protections. Regulation 2025/422 does not prescribe this complete clause package or require publication of every raw dataset or proprietary model. Secure the access needed for validation and lawful disclosure without promising rights the vendor cannot grant.
Keep a versioned evidence file connecting each published figure to its source, calculation, period and approval. Use a common methodological baseline for the white paper and venue. Explain any justified differences in dates, boundaries or calculations before publication; forcing unlike measurements to match would conceal the problem.
Set an update process before admission
The venue’s sustainability information must be freely available as a downloadable, readable file that facilitates comparison between assets. Apply the language requirements for its home and relevant host Member States. (Regulation 2025/422, Article 3(1) and (3).) For the white paper, use the prescribed single XHTML file with Inline XBRL tagging. These format rules have applied since 23 December 2025. (Implementing Regulation (EU) 2024/2984, Articles 2 and 4.)
The CASP must review and update the information at least annually. Material changes require an update without undue delay, with clear indications of the changes and publication and latest-review dates. White-paper sustainability information must also be reviewed and updated regularly; that provision does not itself set the CASP’s annual minimum for white papers. (Regulation 2025/422, Articles 2(1) and 3(2).)
For an ordinary-token white paper, a significant new factor, material mistake or material inaccuracy capable of affecting the token’s assessment triggers MiCA’s modification procedure. Notify the competent authority of the modified documents, reasons and intended publication date at least seven working days before publication. Retain the required version history. (MiCA, Article 12(1)–(3), (6)–(7) and (9).)
The contract and internal process should therefore trigger review when the network changes, the token migrates, node assumptions or emissions factors change, or the vendor discovers an error. Assign a person to assess materiality, coordinate the two publication processes and correct affected marketing. The annual review date must not become a reason to leave a material error unaddressed.
The immediate sequence is to confirm the lawful trading route, identify the disclosing entities, commission the missing technical work and correct unsupported claims. Then approve the indicator files, supplier rights and update responsibilities before admission.
