Karst Stone Paper is committed to the highest standards for our stone paper notebooks, planners, and journals. This commitment rings true throughout all aspects, not just the design. That's why we continually monitor the full life cycle of our products (not just the manufacturing process) and have earned the following certifications:  


Certifications | Karst

C2C CradletoCradle

Our stone paper is CradletoCradle Certified Silver. That means we are committed to continuous improvement standards and are always working toward better practices in material reutilisation and water stewardship in our manufacturing process. But that’s not all, C2C certification assesses the entire product life cycle, so you can rest assured our stone paper doesn’t harm the planet even when you’re done using it. 


ISO 14001 and ISO 9001

The quality management system of our manufacturers is assessed against provisions designed to make sure companies continually meet and exceed their environmental and customer quality standards.


REACH Compliant

REACH is a legislative regulation for chemicals in the European Union to ensure strong protections for that of human health and the environment. This regulation aims to protect both people and planet from the harms of chemicals and promotes alternative methods to the testing of substances.


RoHS Compliant

RoHS stands for Restriction of Hazardous Substances, meaning our products are free from toxic substances such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates (DEHP, BBP, BBP, DIBP). These chemicals pollute landfills and are dangerous to water sources, and are also extremely hazardous to people if exposed in an occupational capacity during manufacture or recycling.


One Tree Planted

We partner with One Tree Planted to support the global reforestation efforts. Not only does this help the environment by planting trees that absorb CO2 from the atmosphere, we’re able to help responsibly employ communities that have been negatively impacted by deforestation.
