The denim and jeans sector is having to work tirelessly to change perceptions over its sustainability, or lack of it. But change is nigh, promises Michael Kobori, vice president of social and environmental sustainability at Levi Strauss & Co. The company recently expanded its Partnership for Cleaner Textiles (PaCT) programme to four countries in Asia, which has so far delivered 20% savings in water and energy consumption for six key vendors. Next on the agenda is a new target to reach 40% savings by 2025.
