Conventional techniques to quantify area-fugitive Greenhouse Gas (GHG) emissions from an open-pit mine have serious drawbacks. The bottom-up approach is based on inventory estimates, in which the emissions from different stationary sources across a mining facility are combined. This approach does not include the atmospheric measurements of GHGs or meteorology and relies on assumptions of the strength of each GHG source within a facility that may not be up-to-date.
