This excel-based package helps GHG inventory compilers manage the information related to the activity data (AD) and parameters in the agriculture, forestry and other land use (AFOLU); energy; industrial processes and product use (IPPU); and waste sectors. Each excel file contains a comprehensive list of AD and parameters that must be collected to estimate all categories within these sectors. This tool must be used in conjunction with the 2006 IPCC Guidelines that provides more explanations on the information needed.
