◦New materials. Our successful track record of commercializing and bringing to market new innovations has made us a desirable partner for many outside R&D companies and vendors, allowing us to be first to market with novel materials while accelerating development timelines and reducing costs. A recent example is our collaboration with Natural Fiber Welding, Inc. to commercialize a 100% natural, plant-based leather-alternative. As we continue to build our library of materials, we plan to create new, differentiated products, as well as leverage new materials across our existing product platforms by refreshing our classic silhouettes.
We estimate that a standard pair of sneakers results in a carbon footprint of 14.1 kg of CO2e. Today, through our use of renewable, natural materials and responsible manufacturing, the average pair of Allbirds shoes has a carbon footprint that is 30% less than our estimated carbon footprint for a standard pair of sneakers, and we offset the entirety of the rest to provide our customers with carbon-neutral products. Furthermore, we believe in the power of selective industry collaboration to accelerate progress, as evident by our partnership with adidas to unveil the world’s lowest carbon footprint running shoe at 2.94kg of CO2e in May 2021. This partnership, as well as our decision to open up the carbon-negative, green EVA used to make SweetFoam, and our carbon footprint methodology demonstrates our ability to scale our impact to the broader industry and beyond, while extending our brand’s leadership as a sustainability innovator.
For example, in 2018, with the help of our partner, Braskem S.A., the petrochemical company and a leading biopolymers producer, we pioneered a carbon-negative green EVA made with Brazilian sugarcane, as an alternative to traditional EVA made from petroleum. We used this new carbon-negative green EVA to create SweetFoam, which is now in all of our shoe soles.
