Dior is beginning its sustainability efforts at the source: its flowers. Since 2006, Dior perfume has been sourced from female flower producers in the Grasse region of France. Over the course of 15 years, the brand has been focused on the cultivation of local flowers and producing harvests that will soon be able to provide all of the key ingredients for Dior perfumes.

Dior has also made the commitment of reevaluating product packaging to ensure it’s not creating unnecessary waste. Today, its refill containers represent 24 percent of units sold, including some of its most popular products like Rouge Dior, its best-selling lipstick, and Sauvage, a men’s perfume.
