AF&PA and a number of other pulp and paper industry associations from around the globe, working through the International Council of Forest and Paper Associations (ICFPA), jointly supported a project to develop international tools for estimating greenhouse gas (GHG) emissions from pulp and paper mills. The group retained NCASI to review existing GHG inventory protocols and to develop calculation tools to assist companies in preparing GHG inventories. NCASI completed this work in 2002, and the tools were released by ICFPA late that year, in association with the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI). In 2004, the Greenhouse Gas Protocol was updated by WRI and WBCSD. This required NCASI to make a number of minor changes to the tools to ensure that they were consistent with the new Protocol. In addition, NCASI took the opportunity to add or expand the guidance on a number of topics.

The calculation tools consist of two parts. The first is this report, which describes the approaches for estimating greenhouse gas emissions from pulp and paper mills. The second is an Excel® spreadsheet to aid in the calculations. Several different versions of the spreadsheet are available on this website and may be downloaded separately.

Below is the latest version of the report, released in July 2005.
