Question 29
AOptions
BSolution
The 'Common Carbon Metric' (CCM), supported by the United Nations Environment Programme (UNEP), was developed to provide a standardized approach for assessing and reporting greenhouse gas emissions. While it can be applied to specific sectors like buildings, its broader aim is to establish a globally consistent method for measuring and benchmarking carbon footprints. Option D, 'assessing the overall carbon footprint caused by the use of fossil fuels by the world in a unit time,' best captures the comprehensive and global scope of the metric in relation to a primary source of emissions, which is crucial for international climate action and policy formulation.
CStrategy
For questions related to international environmental initiatives or metrics, try to understand their overarching goal and the specific problem they aim to address. Look for the most comprehensive and accurate description of their function, often involving standardized measurement or global assessment.
