UPSC Prelims 2021 question on Common Carbon Metric

The 'Common Carbon Metric', supported by UNEP, has been developed for

  1. assessing the carbon footprint of building operations around the world
  2. enabling commercial farming entities around the world to enter carbon emission trading
  3. enabling governments to assess the overall carbon footprint caused by their countries
  4. assessing the overall carbon foot-print caused by the use of fossil fuels by the world in a unit time
Show answer

Answer: A. assessing the carbon footprint of building operations around the world

The Common Carbon Metric is the calculation used to define measurement, reporting, and verification for GHG emissions associated with the operation of buildings types of particular climate regions. It does not include value-based interpretation of the measurements such as weightings or benchmarking.

While it is not a building rating tool, it is consistent with methods for assessing the environmental performance of buildings used globally.

The Common Carbon Metric is applied to the specific inventory of the buildings under study. Such an inventory can be developed from a top-down or bottom-up approach, depending on the scope and goal of the investigation.

Hence, option (a) is the correct answer.
