Unit meaning: Each field uses its source-defined unit and retains the applicable project, baseline, effect, gas, period, component and method.

Table fields and units

  • Project baseline GHG emissions
  • Reported value and unit
  • Project or baseline status
  • Period and method notes

Published dimensions

  • Project
  • Baseline scenario
  • Period
  • Gas

No single formula

Report the source-defined result with its stated fields and method disclosures. Source occurrences are consolidated into project-baseline-ghg-emissions while preserving organization, scope, named-gas, method, period and boundary distinctions.

Verified sources

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.

Method disclosures required

Source-edition basis: GHG Protocol Project Accounting Package, Current-in-force package: November 2005 with 2006/2007 supplements.

  • Project boundary and baseline scenario
  • Project type, geography and technology
  • Reporting or crediting period
  • Included gases, GWP source and unit
  • Quantification, monitoring, uncertainty and verification methods
  • Package component and conditional applicability

Record-specific limitations

  • Combine only non-overlapping observations with compatible project boundaries, baselines, periods, gases, units and quantification methods.
  • Baseline emissions, project emissions, reductions, removals, carbon stocks and credits remain separate unless the source explicitly defines a structured result.

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.
