The world’s highest mountains are some of the most breathtaking places on Earth, but they’re also some of the most fragile.
As more and more people have taken to the mountains, the amount of waste left behind has grown too. Tents, oxygen cylinders, climbing equipment and rubbish can all be found on some of the world’s most iconic peaks.
Nimsdai believed that climbing these mountains came with a responsibility to protect them.
And that belief became the Big Mountain Clean Up.
Since it began, we’ve worked alongside local communities and partners to remove more than 1,600kg of waste from Everest, K2 and Manaslu, helping to protect these extraordinary environments for future generations.
It’s something we’re incredibly proud of, but there is still so much more to do. And it doesn’t have to be on an 8,000-metre mountain.
Through our local Trash Treks, we bring that same idea closer to home, getting people together to pick up litter from our beaches and local communities.
Because whether it’s Everest, a local beach, or the park around the corner, these are places we all enjoy, and we all have a responsibility to look after them.
It was something Nimsdai cared deeply about, and it’s something we’ll continue.
