Accounting for Whole Life Cycle
To ensure that the global expansion of timber construction reduces – rather than accelerates – climate and environmental harm, we must consider the whole life cycle of every project. Carrying out comprehensive whole-life carbon assessments establishes the foundation for responsible timber construction by enabling accountability, driving innovation, and ensuring that scaling bio-based materials strengthens forests and communities. However, the industry must close data gaps, standardise assessment methods, and expand professional training to align timber’s growing role with genuine climate performance and wider environmental integrity.
