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 footprint caused by the use of fossil fuels by the world in a unit of time

Explanation

Option (a) is correct

• Common Carbon Metric (CCM) is an internationally recognised tool developed to measure and report the carbon emissions from buildings, specifically their operations. Supported by the United Nations Environment Programme (UNEP), this metric plays a vital role in addressing the significant impact of buildings on global carbon emissions. The purpose of a Common Carbon Metric for buildings is to give the sector that represents 40% of the world’s energy consumption and related 1/3rd of global greenhouse gas (GHG) emissions a tool that provides a way to measure, report, and verify reductions in a consistent and comparable way. It provides a consistent framework for evaluating and comparing the environmental performance of buildings.
