Our Business and Beyond

Overconsumption is a major contributor to the current climate crisis. It is also one of Sweden's largest environmental impacts, more than twice the size of our flight emissions. The average Swede buys 13 kilos of new clothes and textiles every year, a third of which are never used. Producing a 169 gram mobile phone causes 86 kilos of waste and many of us use our phones for less than two years.
