ISO/TC 287/WG 3 - Sustainability aspects

This document provides examples and background literature for identifying and calculating greenhouse gas displacement potential for wood-based products as defined in ISO 13391-3:2025, including the calculation of displacement factors. This document also provides a review of considerations for further analyses that address the impact of these potentials over time in a broader economy setting.

This document provides background information, methods and examples of calculating contributions to carbon stored in wood-based products (harvested wood products, HWP), including storage resulting from HWPs in landfill and bio-CCS, as defined in ISO 13391-1:2025. It includes background to the tier 1 HWP coefficients for various wood-based product categories defined in ISO 13391-1:2025.
