Value structure

Dimensions and units

Unit
number of structures — source-defined reporting unit
Reporting basis
Not specified in extracted source

Unit meaning: Values use number of structures under the disclosed TNFD sector-guidance method, reporting period and boundary.

Published dimensions

  • Sector: Oil and Gas
  • Official metric code: OG.A2.0
  • Impact-driver category: Pollution/pollution removal
  • Removal status: not fully removed and remaining in place

Calculation method

Formula information

Status
Specified
Formula type
Count

Formula

N_remaining = COUNT(decommissioned infrastructure structures that have not been fully removed and remain in place).

Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. OG.A2.0 is a standalone, directly reportable count with an explicit population and status condition. No shortlisted existing metric has the same construct, boundary, value shape and unit.

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: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).

  • Define the infrastructure structures included in the count.
  • State the reporting-date or reporting-period basis used for identifying structures remaining in place.
  • Describe the criterion used to determine that a structure has not been fully removed.
  • State the geographic and operational boundary covered.

Record-specific limitations

  • The extracted source does not specify the reporting period or whether the count is measured at a reporting-date snapshot or across a period.
  • The extracted source does not define infrastructure-structure types, geographic coverage, or treatment of partially removed structures beyond not being fully removed.

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.
