Between her inspiring work as UN Women Goodwill Ambassador and her busy acting schedule (Beauty and the Beast included), Emma Watson has found the time to nurture a new cause, and it relates to fashion.

The actress, who has made Vanity Fair’s International Best-Dressed List for the past few consecutive years, has embarked on her own fashion challenge during the current press tour for Alejandro Amenábar’s Regression. Her goal: encouraging a green carpet, rather than red, full of stylish ensembles from designers who do not use fur or chemicals that could harm the environment.

Inspired by Andrew Morgan’s recent documentary, The True Cost, which explores the disturbing underbelly of "fast fashion," Watson began the challenge with the following message posted on Instagram: "Inspired to consider the whole process of creating a fashion look, we are thinking about all the people, pieces and moving parts! This rack includes designers that are considering local craft and production, artisan skills, the environment, sustainability and the longevity of fashion!"

The actress has also highlighted some of her recent eco-friendly styles on Instagram.

In a review of The True Cost this May, the New York Times recounts the horrors that the documentary uncovers in the fast-fashion industry including "zealous pesticide use," underpaid factory workers who are abused to meet America’s affordable demands, and clogged landfills. The review ends as follows: "The True Cost stirs and saddens. Not least because it’s unlikely to reach the young consumers most in need of its revelations."

Hearteningly, Watson wants to use her celebrity to reach that exact demographic.
