Explanation

The 'Common Carbon Metric' (CCM), supported by the United Nations Environment Programme Sustainable Buildings and Climate Initiative (UNEP-SBCI), was specifically developed for assessing the carbon footprint of building operations around the world. It provides a standardized protocol for measuring, reporting, and verifying greenhouse gas emissions from the use and operation of buildings. The CCM enables consistent comparison of building energy performance and carbon emissions across different countries and building types, supporting efforts to reduce the building sector's significant contribution to global emissions.
