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 has completed calculation tools for GHG emissions from wood product facilities. An Excel workbook that aids the user by automating the calculations has also been developed. There are two versions of the workbook - one using measurement units familiar to US operations and another using units familiar to Canadian operations.

As with the pulp and paper tools, the calculation tools 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.

NCASI members may access Version 3.1a of this tool, which includes data entry forms containing emission factors, fuel property characteristics, and physical unit conversion factors drawn from the Canadian Voluntary Challenge and Registry (VCR) guidance.
