Unveiled at this year’s Global Fashion Summit in Copenhagen, Denmark – an international forum focused upon sustainability in fashion – the ultimately comfy footwear brand Allbirds revealed their latest efforts to alter the trajectory of footwear’s environmental impact with M0.0NSHOT, a minimalist Merino wool upper sneaker they’re hailing as the “world’s first net zero carbon shoe.”

This isn’t Allbird’s first effort to reduce the environmental impact attributed to midsole manufacturing. Back in 2018 the brand developed a midsole foam made from carbon negative, sugarcane-derived green EVA. In 2021, they also partnered with adidas to create a 2.94 kg CO₂e shoe, the lowest carbon footprint in the world at that time.

Much of the M0.0NSHOT’s zero carbon attributes can be credited to the use of regenerative wool, a material sourced from Lake Hawea Station in New Zealand, a net zero carbon farm producing superfine premium merino wool that also sequesters more carbon by integrating native plantings, ground clearing, and new pasture species for their livestock.
The shoe’s soft knitted bootie-like upper is made with superfine premium merino wool sourced from The New Zealand Merino Company’s regenerative wool program, ZQRX. The midsole is manufactured from a sugarcane-derived foam midsole with 70% bio-based content. And even the shoes eyelets are a carbon-negative bioplastic, made from microorganisms that convert methane into a polymer that can be molded into the small detailing required of footwear. By all appearances, M0.0NSHOT should offer a very comfortable fit, with durability a question only to be answered once production goes into effect.
We could spend decades debating the finer points of carbon sequestration, or we can innovate today with a common sense approach. It’s about progress, not perfection. The scientists have shown us what’s possible – now it’s time for the fashion industry to carry the open-sourced learnings from M0.0NSHOT forward.
