MetricSub-sovereign production-based GHG emissions

Sub-sovereign production emissions intensity

Measurement answer

What this metric measures

An optional intensity measure that normalizes a sub-sovereign entity's production emissions by its PPP-adjusted GDP for comparison across sub-sovereign entities.

Specification

Metric specification

Result format
Single value
Unit
tCO₂e per PPP-adjusted GDP — source-defined reporting unit
Reporting basis
Reporting period for which production emissions and PPP-adjusted GDP are measured
Aggregation
Reported for the applicable sub-sovereign entity, such as a region, city, or local government
Pillar

Topic
Sub-sovereign production-based GHG emissions
Controlled domain
Climate and greenhouse gases

Metric

Reporting boundary

Production emissions divided by PPP-adjusted GDP; excludes Scope 2 emissions, Scope 3 emissions, and exported emissions because of data limitations.

Value structure

Dimensions and units

Unit
tCO₂e per PPP-adjusted GDP — source-defined reporting unit
Reporting basis
Reporting period for which production emissions and PPP-adjusted GDP are measured

Unit meaning: Values use tCO₂e per PPP-adjusted GDP under the disclosed PCAF Part A method, period and boundary.

Calculation method

Formula information

Status
Specified
Formula type
Ratio

Formula

I_production = E_production / GDP_PPP

Apply the stated PCAF Part A method only within the disclosed boundary and with compatible inputs. The source explicitly defines this optional ratio, its numerator and denominator, and its exclusions. It is a distinct sub-sovereign production-emissions intensity, not the existing financed-emissions economic-intensity identity, whose denominator is a financial institution's amount loaned or invested.

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.

Source-edition basis: Global GHG Accounting and Reporting Standard — Part A, Third Edition, December 2025.

  • Disclose that the metric is calculated using production emissions and PPP-adjusted GDP.
  • Disclose the exclusion of Scope 2, Scope 3, and exported emissions from the emissions boundary.

Record-specific limitations

  • Scope 2, Scope 3, and exported emissions are excluded due to data limitations.
  • The measure is an optional normalization metric and does not represent financed emissions attributable to a financial institution.

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.
