In April, Olivia launched an environmentally conscious line of clothes for H&M. The Conscious Exclusive collection is made of sustainable materials.
'I hope the collection empowers women around the world who love fashion but want to consume it in a more sustainable way. It gives them the chance to look their best, and also act responsibly. I also hope the rest of the fashion industry is watching. I think this is how all fashion should be. Great style that's naturally more sustainable,' she said of the line.
The star is also co-founder of Conscious Commerce, as site that ensures when you buy something the money actually goes to help the people who made it.

The busy star recently wrapped production on the Christmas-themed comedy Love The Coopers with Amanda Seyfreid, Marisa Tomei, John Goodman and Diane Keaton.
She's also spent a lot of time promoting the Ebola documentary she produced, Body Team 12, which debuted at the Tribeca Film Festival in April.
