Preserved Wood and the Environment

Enviro 1

Preserved wood offers many environmental benefits compared to alternative materials. It is the only construction material made from a sustainable, renewable resource and the application of preservatives extends the natural life of the wood from years to decades.

Assessing the environmental benefits of any building product requires a more systematic, science-based approach rather than the subjective and sometimes misleading claims that are often promoted. The preserved wood industry commissioned a series of assessments using internationally recognized life cycle science to provide an objective basis to determine environmental benefits.

Life Cycle Assessments (LCAs)

The process of conducting a Life Cycle Assessment considers the full cradle-to-grave perspective on a product. The LCAs for preserved wood products shown below were done according to ISO 14044 standards and have been subject to scientific peer review to confirm the results.
