The Klean Kanteen brand aims to reduce single use, plain and simple. The brand then takes a holistic approach to understanding and managing the environmental footprint of their products. This starts from raw material sourcing to manufacturing, packaging, shipping, daily use and end-of-life disposal. Klean Kanteen uses a life cycle assessment process and other tools to uncover hidden impacts, track their progress from year to year, and think of ways to improve. As a result of their thinking and positioning as a company (in relation to the environment and humans), Klean Kanteen is achieving Climate Neutral certification in 2019. But also: every time you make a Klean (Kanteen) purchase, the brand donates 1% of the sale to organizations working to make the world more resilient and sustainable.
