Kering SA, the French owner of luxury fashion houses such as Gucci and Saint Laurent, is requiring suppliers to meet treatment standards for animals used in products like leather handbags and cashmere suits.

By 2025, the company globally will apply European Union standards for animal welfare—considered to be among the world’s most rigorous and which include unfettered access to clean water and room to move freely.

For suppliers already meeting these requirements, the company said Monday it wants to encourage further improvements like allowing free grazing for cattle or making sure ostriches have enough space to run.
