Measurement answer

What this metric measures

Regulated-emission-allowance stock at period start is a structured disclosure of compliance instruments held under a named scheme, with banked prior-period allowances identified as a subset.

Reporting boundary

Compliance instruments held at the beginning of the reporting period under a named regulated emissions-trading scheme. Banked prior-period allowances are a subset of the total count, and any emissions equivalent is reported only when the named scheme legally defines it.

Unit meaning: This metric is reported as a structured table; each field carries the unit stated in the table fields below.

Table fields and units

  • Regulated emissions-trading scheme and jurisdiction
  • Measurement date, registry account or installation
  • Allowance vintage, compliance period and origin
  • Allowances held (count of scheme-issued compliance instruments)
  • Banked prior-period allowances (subset count; never added to total held)
  • Authorised emissions equivalent (tCO₂e — only when the named scheme legally defines the conversion)
  • Missing-value or scheme-validation status

Published dimensions

  • Regulated allowance-stock row
  • Regulated emissions-trading scheme and jurisdiction
  • Registry account or installation
  • Allowance vintage or compliance period
  • Allowance origin and balance type
  • Beginning-of-period measurement date

Evidence and status sources

Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Interpretation boundaries

Method disclosures required

Source-edition basis: Binding Commission Delegated Regulation (EU) 2023/2772 consolidated 1 January 2025, ESRS E1 AR74(b)-(c), plus the scheme-specific EU ETS definition where applicable; the adopted-pending July 2026 ESRS annex omits the datapoint.

  • Named regulated emissions-trading scheme and jurisdiction
  • Beginning-of-period measurement date, registry account or installation
  • Allowance vintage or compliance period, origin and balance type
  • Allowances held as a count of scheme-issued compliance instruments
  • Banked prior-period allowance subset count, never added to total allowances held
  • Optional tCO₂e equivalent spelled out as metric tonnes of carbon dioxide equivalent and supported by the named scheme's legal rule
  • Unavailable fields and reasons, never silently represented as zero
  • Current ESRS authority and adopted-successor omission warning

Record-specific limitations

  • The instrument count is not monetary value, accounting liability, surrendered allowances or annual purchase requirement.
  • Banked prior-period allowances are a subset of total allowances held and must never be added to that total.
  • Different schemes are not combined because instrument definitions, compliance periods and conversion rules differ.
  • The EU ETS one-tonne rule is not universal and cannot be applied to another scheme without its legal conversion rule.
  • The adopted-pending July 2026 ESRS annex omits this optional current-edition datapoint.

Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.

Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
