Dianna Cohen

Dianna Cohen is an American visual artist and activist.

She is the CEO and co-founder of the Plastic Pollution Coalition, an advocacy group and social movement organization which seeks to reduce plastic pollution.

Cohen grew up in Los Angeles.

Her father was a filmmaker, and her mother the director of the Los Angeles Free Clinic.

She attended UCLA, where she studied biology before shifting her major to art.

Following her graduation, Cohen began working in collage, initially using deconstructed brown paper bags, and later incorporating plastic.

Her first solo exhibition of the bag series was in 1994.

After eight years of working with plastic bags, Cohen realized the plastic was degrading.

In 2009, after learning about the Great Pacific garbage patch, she founded the Plastic Pollution Coalition (PPC) with her sister, Julia Cohen, Manuel Maqueda, Daniella Russo and Lisa Boyle.

She has led the Plastic Pollution Coalition's efforts to eliminate the use of single-use containers for beer, water and other drinks at music festivals and concerts.

Cohen has received awards for her environmental activism.

In a 2015 interview she said: “At first I got excited because I thought that it meant the plastic bags were ephemeral and organic like us, and that they had a finite lifespan.” In researching the subject, she discovered that "plastic photodegrades or heat-degrades by breaking apart, but does not disappear."

In 2016, she was presented the inaugural Snow Angel Award by the Sun Valley Film Festival.

Cohen and her partner, Jackson Browne, live in Los Angeles.

She was named Environmentalist of the Year by SIMA in 2019.

They were co-executive producers on the 2020 documentary The Story of Plastic. She has surfed since 1996.
