In the United Kingdom, Teysha Technologies is supplying four former special forces soldiers with biodegradable sunglasses as they attempt a world record on the world’s highest peak. Summiting Everest and returning to base camp typically takes two months, but the team will attempt the journey in just a week. By significantly shortening the expedition timeline, the expedition will reduce carbon emissions by an estimated one-third by limiting time at Base Camp, eliminating methane by not using yaks to carry supplies, and cutting food consumption and human waste to just 10% of that generated by a typical ascent.

The high-performance, biodegradable sunglasses are made from Teysha Technologies’ proprietary plant-based polymers. The specialized eyewear can withstand temperatures as low as -40°C while maintaining optical clarity and protection against harsh mountain conditions.

“Mountaineering is a pursuit that depends on the preservation of nature, yet climbing equipment has long relied on materials that damage our mountains and wilderness areas,” Matthew Stone, CEO of Teysha Technologies, said in a press statement.  “We are proud to play our part in Mission Everest by providing a high-performance, nature-based alternative to plastic

The Mission: Everest team is comprised of Kevin Godlington, Veterans Minister Colonel Al Carns, Major Garth Miller, and Anthony “Staz” Stazicker. The team hopes to raise £1 million for veterans charities, amongst them Scotty’s Little Soldiers, a charity that provides vital support to bereaved children and young people who have lost a parent in the British Armed Forces.
