Until recently, no method existed to mathematically calculate the sustainability of one material over another. As the technology evolves, Life-Cycle Assessment is gaining more acceptance. The process involves evaluating all the environmental effects of decisions and processes over the life of the product, from resource extraction to disposal.

In recent years, the US Treated Wood Council has undertaken life cycle assessment of treated wood compared to other materials used in the same project category.
