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.

Overview

ISO/TR 25080:2025 is a Technical Report that explains background, methods and worked examples for estimating the contribution of wood and wood‑based products to carbon stored in harvested wood products (HWP). It supports the framework in ISO 13391‑1:2025 by detailing the HWP coefficient concept, data needs, modelling approaches (tier 1–3) and treatment of long‑term storage pathways such as landfill and bio‑CCS. The report aligns with IPCC approaches for greenhouse‑gas dynamics of wood products and provides practical examples for organizations and national reporters.

Key topics

HWP coefficient concept: definition as the proportion of product inflow that represents a net change in the HWP carbon pool.

Tiered methods: overview of IPCC‑aligned approaches (tier 1, tier 2 and tier 3) to estimate HWP carbon dynamics.

First‑order decay modelling: use of decay functions and product residence times to estimate outflows from the HWP pool.

Data requirements: what is needed to calculate HWP coefficients (product delivery volumes, historical market trends, half‑lives, recycling rates).

Recycling and market growth: how recycling flows and changing product markets affect HWP storage estimates.

Landfill and other long‑term storage: tiered methods for carbon stored in landfills, bio‑CCS and non‑standard landfill considerations.

Worked examples: step‑by‑step examples using national inventories, market data and organization‑specific data, with sensitivity notes.

Applications

ISO/TR 25080:2025 is practical guidance for:

Carbon accounting and organizational greenhouse‑gas reporting for companies producing or using wood‑based products.

Life cycle assessment (LCA) practitioners requiring consistent treatment of biogenic carbon in HWPs.

Sustainability reporting (corporate and value‑chain level) where HWP contributions to carbon storage are disclosed.

Forest‑product manufacturers, traders and brand owners estimating carbon storage from sold products.

Consultants, auditors and regulators validating HWP calculations in claims, standards or policy frameworks.

Researchers and national inventory compilers refining tier 2/3 methods or comparing IPCC approaches.
