"Whoever takes something from nature must also give something back," which is why Gollnest & Kiesel, known as GoKi, plants a new forest in the forest-poorest state of Schleswig-Holstein every year - one tree 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 they are working to make as many products as possible circular, meaning cradle-to-cradle. Gollnest & Kiesel is also socially engaged worldwide, helping to build schools in developing countries, giving children the opportunity for education. It goes without saying that no GoKi toy is made by children: "We make toys for children, not by children." In GoKi's own factory in China, Western standards are upheld regarding occupational safety and security. Toys should be fun and safe. To ensure the highest safety standards, the GoKi quality management team constantly tests all products in their in-house laboratory. External testing institutes also regularly conduct extensive tests on GoKi products.
