Protected Areas Network metric - GBF 3.CY.4
Measurement answer
What this metric measures
Reports the official CBD GBF 3.CY.4 complementary indicator “Protected Areas Network metric” at its national, regional or global reporting population. Goal or target links and optional disaggregations remain dimensions rather than duplicate metrics.
Specification
Metric specification
- Result format
- Format varies by method
- Unit
- Structured table — field-level units: Source-defined unit or scale - see indicator metadata
- Reporting basis
- Applicable national reporting cycle or the observation and reference period defined by the indicator methodology
- Aggregation
- Aggregate only observations sharing the same official indicator code, method version, unit or scale, reporting population, geography, period and disaggregation. Binary indicators aggregate eligible country responses rather than questionnaire choices.
- Pillar
- Environmental
- Topic
- Biodiversity monitoring and nature outcomes
- Controlled domain
- Nature, biodiversity and land
- Entity type
- Metric
Reporting boundary
The Party, national, regional or global geography and reporting population defined by the official indicator methodology; preserve subnational populations and optional disaggregations when reported.

Value structure
Dimensions and units
- Unit
- Structured table — field-level units: Source-defined unit or scale - see indicator metadata
- Reporting basis
- Applicable national reporting cycle or the observation and reference period defined by the indicator methodology
Unit meaning: Each table field uses its stated unit. Use the unit, scale, numerator, denominator and value shape defined by the indicator metadata maintained for the applicable CBD reporting cycle.

Disclosure form
Apply the official metadata and calculation method for the named GBF indicatorThe Decision 16/31 table establishes the governed identity but does not prescribe one universal formula for every indicator. Sustopedia therefore preserves the source method by reference instead of inventing arithmetic.
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.

Interpretation boundaries
Method disclosures required
Source-edition basis: Decision 16/31, reissued 3 June 2025
- State the official GBF indicator code, indicator class and method or metadata version applied.
- State the reporting population, geography, reference period, unit or scale, numerator and denominator where applicable.
- Preserve all goal or target applicability and optional disaggregations without creating duplicate indicator identities.
- Disclose data source, estimation, aggregation, exclusions, uncertainty and any departure from the official methodology.
Record-specific limitations
- Decision 16/31 establishes the indicator identity and authority class; calculation details and units can depend on separately maintained indicator metadata.
- National, regional and global results are not interchangeable with similarly named corporate, product, project or investment metrics.
- Component and complementary indicators are voluntary; that authority status must remain visible when interpreting coverage.
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.
