Solution:Common carbon metric for measuring energy use and reporting greenhouse gas emissions from building operations.Leading experts from around the world have, through extensive international cooperation, developed a universal method of measuring a building's carbon footprint.
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.
While it is not a building rating tool, it is consistent with methods for assessing the environmental performance of buildings used globally such as the World Business Council for Sustainable Development (WBCSD), World Resources Institute (WRI) GHG Protocol, etc.
