YKK shared that beginning in fiscal year 2024, it will begin purchasing alloy wires that utilise low-carbon aluminium for use as materials in aluminium alloy zippers, and gradually expand their application.

The manufacturer pointed out that the adoption of low-carbon aluminium as a material for zippers is one of its initiatives to achieve the reduction target for Scope 3 emissions.

Terry Tsukumo, vice president of the product strategy division at global sales headquarters, YKK Corporation, said: “Up to this point, YKK has been working to reduce GHG emissions by increasing the use of recycled materials and plant-based materials in textile materials for zippers and switching to eco-friendly products. In addition to this, low-carbon aluminium is a new YKK initiative to reduce the environmental impact of metal materials used for zippers. We will continue to work with our business partners to reduce our environmental impact throughout the supply chain.”

The manufacturer adopted Sustainability Vision 2050, its sustainability goals for achieving climate neutrality by 2050, and set targets under the five themes of climate change, material resources, water resources, chemical management, and respecting people.
