GoKi is committed to nature: "Whoever takes something from nature must also give something back." Therefore, Gollnest & Kiesel donates a new forest every year to the state of Schleswig-Holstein, which has the least forest cover – a tree is planted for every newborn child. Since 2004, more than 400,000 beech, oak, and maple trees have been planted. Only wood from sustainable European forestry is used, and the company is working to produce as many products as possible in a circular manner, meaning cradle-to-cradle.

Gollnest & Kiesel is also socially engaged worldwide by establishing schools in developing countries, giving children the opportunity for education. It goes without saying that no GoKi toys are made by children: "We make toys for children, not by children." In the GoKi-owned factory in China, Western standards regarding occupational safety and security are upheld. Toys should be fun and safe. To ensure the highest safety standards, the team in GoKi's quality management constantly tests all products in their in-house laboratory. External testing institutes also regularly examine GoKi items in extensive tests.
