Growing up, Stella McCartney was a vegetarian, living on an organic farm in the English countryside. The idea of sustainability was ingrained in her from an early age so it comes as not surprise that McCartney does her best to incorporate sustainability into her business and personal life, even as she admits it can be a challenge. While the fashion industry is one of the least sustainable on the planet, we all have to wear clothes, so when it comes to fashion, for McCartney, it is the decisions about which clothes that count.As one of the most successful designers in the world, McCartney is one of the few who has bridged haute couture and mainstream fashion - and with that bridge she has brought sustainability to the forefront of fashion. At any price point, a Stella McCartney piece is an investment that is created to last. McCartney knows how sustainably expensive the production of clothes and she states, "I believe in creating clothes that aren't going to landfills, that aren't going to damage the environment."In her personal life, Stella McCartney talks openly about the reality of incorporating sustainability into modern day life. "I'm not perfect, I travel on airplanes, I drive a car, but I recycle and the electricity in the house comes from wind power. I turn the light off when I leave a room." McCartney puts a high importance on being aware, and understanding how her decisions, in the small everyday actions of her personal life and the bigger impact of her business, will affect the environment. "I'm aware and I ask questions - when we can make things better, we do it.
