Two sustainable footwear brands have joined forces to reduce the 700m metric tonnes of carbon dioxide emitted by the footwear industry annually.

The partnership aims to create an innovative manufacturing and supply chain process coupled with the use of renewable resources to create the lowest carbon footprint ever recorded for a sports shoe.

adidas and Allbirds will combine their individual sustainable innovations in the footwear industry to unlock the opportunity to set the new industry standard.

"Our brands don't want to just participate in the sustainability conversation, we want to continue being catalysts and creators of substantial improvement," said James Carnes, VP of adidas Brand Strategy.

"The recent progress that our brands have made in the name of sustainable innovation has created the perfect momentum for this partnership to influence industry practices forever."

"There is an urgent need to reduce our global carbon number, and this mission is bigger than just Allbirds or adidas," said Tim Brown, co-CEO of Allbirds.

The collaboration will explore innovations across the entire supply chain from material choices to manufacturing processes whilst still maintaining that the end result will not compromise performance.

The project is dedicated to creating an athletic shoe that meets adidas performance standards, which are among the most stringent in the industry.

adidas has committed to a 30 percent reduction in its carbon footprint by 2030 and carbon neutrality by 2050 whilst Allbirds' "Tread Lighter" program represents its ongoing practices to measure and reduce emissions across its entire business.
