The direct-to-consumer footwear brand Allbirds has partnered with a design academy to offer a three-week master class on sustainable design, for free.

The master class is the outgrowth of a collaboration between Pensole and Allbirds, which is best known for its comfortable shoes made from natural materials such as eucalyptus tree fiber and sugar cane. It’s part of a larger push among brands to partner with design academies on environmentally minded projects. Last year, Nike released a manual with Central Saint Martins focused on circular design. The handbook uses design principles and case studies to show creatives the possibilities of designing with sustainability in mind.
The Pensole course on sustainable design is accepting applications through March 9. To apply, go here.
