Greenhouse gas emissions from large facilities indicator: data sources and methods, chapter 4

4. Methods

The quantity of greenhouse gases (GHGs) released by each facility is calculated by the reporting facility based on monitoring or direct measurement, mass balance, emission factors, engineering estimates and fuel and production data. Although estimation methods are not prescribed by Environment and Climate Change Canada, reporting facilities are advised to choose the quantification methodologies most appropriate for their particular industry or application. Facilities must use methods for estimating emissions that are consistent with the guidelines developed by the Intergovernmental Panel on Climate Change and adopted by the United Nations Framework Convention on Climate Change, for the preparation of national GHG inventories.
