YKK’s Sustainability Vision 2050 aims for climate neutrality and coexistence with nature by 2050. The company targets 10 SDGs through themes of climate change, material resources, water resources, chemical management, and respect for people. Progress is detailed in the Integrated Report, with additional data on environment, society, governance, and finance in the Data Book.
Innovation Highlights
- Copper and Zinc Recycling: Developed proprietary in-house recycling technology for copper and zinc alloys used in YKK zippers
- Sustainable Packaging: Switched to Forest Stewardship Council (FSC)-certified packaging at the Kurobe Manufacturing Center
- Chemical Management: AcroPlating technology now accounts for 25% of brass slider sales, a 7-point increase from last year.
- Product Longevity: Launched the Revived Renewal Series to extend zipper lifespan
Environmental Recognition
The company’s dedication to biodiversity has been acknowledged with the designation of YKK Center Park’s Furusato-no-Mori (Hometown Forest) as a Nature Coexistence Site, underscoring YKK’s leadership in corporate environmental stewardship.
Looking Forward
Building on these achievements, YKK has revised its Sustainability Vision 2050 to strengthen its focus on three critical areas:
