Correct Answer: Option A
The Common Carbon Metric, supported by UNEP, is used to define the measurement, reporting, and verification of Greenhouse Gas (GHG) emissions specifically associated with the operation of buildings in particular climate regions.
It focuses on the quantification of emissions and does not include any value-based interpretation (e.g., weightings or benchmarking).
It is consistent with global methods for assessing the environmental performance of buildings, though it is not a building rating tool itself.
The metric is applied to a specific inventory of buildings, which can be developed using a top-down or bottom-up approach.
Therefore, option (a) is the correct answer.
