Abstract

Wood is an essential construction material because of its renewable nature, versatility, and ability to store carbon, which aids in climate change mitigation. However, its biodegradability requires preservation treatments to prolong its service life and improve its durability. This study compares international wood preservation regulations with the Chilean framework and evaluates their alignment with Environmental, Social, and Governance (ESG) criteria and the Sustainable Development Goals (SDGs). The findings reveal a global trend focused on reducing hazardous preservatives like chromated copper arsenate (CCA) while promoting environmentally friendly alternatives. The discussion emphasizes the need for strategic regulatory updates and investment in sustainable wood protection technologies. These efforts are essential for ensuring long-term structural performance, resource efficiency, and market competitiveness. © 2025 by the authors.
