GHG Calculation Tools for Wood Products Facilities

March 10, 2022

With financial support from AF&PA and FPAC, and considerable assistance from a working group of wood products experts from FPAC, AF&PA, and NCASI member companies, NCASI completed development of a calculation tool for GHG emissions from wood product manufacturing facilities in 2004. The International Version of the tools have been updated in 2022 to reflect updated Global Warming Potentials.

The calculation tool consists of two parts: 1) a report (PDF) that describes the approaches for estimating greenhouse gas emissions from wood products facilities, and 2) an Excel spreadsheet to aid in the calculations.

As with the pulp and paper tool, the calculation tool for wood products manufacturing facilities incorporates default approaches and emission factors which are consistent with guidance from the IPCC. These defaults can be overridden by companies as appropriate. The tools reflect many of the features of well known and widely accepted protocols such as the “GHG Protocol” issued by WRI/WBCSD, the “Climate Leaders Greenhouse Gas Inventory Protocol Core Module Guidance” issued by USEPA. Originally released in July 2004, this version was last updated in March 2022.

This user-friendly version of the tool was designed specifically for Canadian facilities, with NCASI data entry forms. The spreadsheet is appropriate for developing estimates to satisfy Canadian reporting requirements and contains commonly used emission factors, fuel property characteristics, and physical unit conversion factors. The spreadsheet has a user-friendly interface and a Quick Start Guide. First released in October 2008, it was last updated in March 2022.
