Percentage of compliant light fixtures
Measurement answer
What this metric measures
Percentage of assessed light fixtures that meet the organization’s disclosed environmental compliance criterion, such as a shielding, cut-off, or wattage requirement.

Formula
P_compliant = 100 × F_compliant / F_assessed.Apply the source-defined TNFD Recommendations method only within the disclosed location, ecosystem and value-chain boundary. A2.3 provides a reportable proportion of fixtures satisfying stated criteria. It is distinct from product-compliance metrics because its population is light fixtures in the disclosed assessed boundary, and the applicable environmental criterion must remain an explicit dimension.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
P_compliant | Compliant light fixtures percentage | Percentage of assessed light fixtures that meet the disclosed environmental compliance criterion. | % |
F_compliant | Compliant light fixtures | Number of assessed light fixtures meeting the disclosed compliance criterion. | count |
F_assessed | Assessed light fixtures | Number of light fixtures in the disclosed denominator population. | count |

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: Recommendations of the Taskforce on Nature-related Financial Disclosures, September 2023.
- Disclose the environmental compliance criterion applied, including any shielding, cut-off, wattage, or other technical threshold.
- Disclose the numerator population of compliant fixtures and the denominator population of assessed fixtures.
- Disclose the fixture inventory boundary, covered locations, treatment of temporary or excluded fixtures, and assessment date or period.
- Disclose whether compliance was directly verified, estimated, or assessed using a proxy method.
Record-specific limitations
- The extracted evidence provides example compliance criteria, including fully shielded, fully cut-off, or under 60W; the applicable criterion must therefore be explicitly identified.
- A compliant-fixture percentage does not itself demonstrate ecological outcome or reduction of nature-related impact.
- Percentages based on different compliance criteria, fixture populations, or geographic conditions are not directly comparable.
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.
