T/CNFPIA 4011-2023 Guidelines for Carbon Footprint Evaluation of Manufactured Panels and Their Products

Scope

Scope: This document specifies the terminology and definitions, evaluation principles, evaluation basis, system processes, biogenic carbon storage, distribution principles, data requirements, calculation of product carbon footprints, and record-keeping and archiving of product carbon footprints for various types of wood-based panels and their products, including fiberboard, particleboard, plywood, fine carpentry boards, reconstituted decorative materials, veneer lumber, integrated timber, finished wood panels, wooden flooring, wooden wall panels, wooden doors and windows, etc. This document is applicable to guiding the evaluation of the product carbon footprints of various types of wood-based panels and their products, including fiberboard, particleboard, plywood, fine carpentry boards, reconstituted decorative materials, veneer lumber, integrated timber, finished wood panels, wooden flooring, wooden wall panels, wooden doors and windows, etc. Main technical content: 3. Terminology and definitions The terms and definitions defined in GB/T 32150-2015 and the following terms and definitions are applicable to this document. 3.1 Uncertainty The parameter associated with quantified results, which characterizes the deviation of the value. This deviation can be reasonably attributed to the quantity being quantified. Note: Uncertainty analysis generally refers to the quantitative estimation of possible deviations in values and a qualitative description of the causes of these deviations.

Note: Examples of fossil materials include coal, oil, natural gas, and peat. [Source: ISO 14067:2018, 3.1.7.3] 3.4 Product carbon footprint The sum of greenhouse gas emissions and removals from a product system, expressed in CO2 equivalents, based on a life cycle assessment considering only th
