Adidas announced today that it will no longer use plastic shopping bags in its stores, a move it says will phase out 70 million plastic bags from 14,000 stores. On Twitter, the brand says it will instead use bags made of recycled paper.

This move toward sustainability was aided by Lisa Breinig, a project manager for adidas' global retail and franchise team. Breinig wrote about the project on adidas' blog.

"Every time we thought that we were on track we received a request from a market asking us to help solve an issue," she wrote, "anything from the new bag specifications to supplier sourcing, etc."

Adidas' announcement is timed to coincide with Earth Day, 2016.
