Tools and Calculators

GHG Calculation Tools for Wood Products Facilities

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 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.

Excel Spreadsheet


Version 1.0a (US units / SI units)          last updated April 2009
As with the pulp and paper tool, the calculation tool for wood products manufacturing facilities incorporate 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, and the “Challenge Registry Guide to Entity and Facility-Based Reporting” issued by VCR in Canada. Originally released in July 2004, this version was last updated in April 2009. Though no longer posted on this website, it is available upon request.

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 emission factors, fuel property characteristics, and physical unit conversion factors drawn from the most recent Canadian Standards Association (CSA) GHG Challenge Registry guidance (formerly the Canadian Voluntary Challenge and Registry, or VCR). The spreadsheet has a user-friendly interface and a Quick Start Guide. First released in October 2008, it was last updated in May 2020. This version is available to NCASI members only.
