New York (CNN Business) Fast fashion retailer Zara is going green. All of the cotton, linen and polyester used by Zara will be organic, sustainable or recycled by 2025, parent company Inditex announced this week.

The Spanish retail conglomerate said the goal will extend to its other brands, including Zara Home, Pull & Bear and Bershka.

Inditex made the sustainability pledge at its annual meeting this week. The use of those fibers, plus a semi-synthetic fiber called viscose, account for 90% of the raw materials used by the brands. Inditex said it will use all sustainable viscose by 2023.

Added up, Inditex chairman and CEO Pablo Isla said, it's "fair to say it's 100% of the raw materials that we use which will be fully sustainable."

"We need to be a force for change, not only in the company but in the whole sector," Isla said at the annual meeting. "Sustainability is a never-ending task in which everyone here at Inditex is involved and in which we are successfully engaging all of our suppliers."
