Why it wins
Karst wins due to its comprehensive B Corp certification and climate neutrality, combined with innovative stone paper that offers superior durability and a unique eco-advantage over recycled paper notebooks.
Overview
Both the Karst Soft Cover A5 Notebook and the Michael Roger Decomposition Notebook earn a stellar ethics score of 92/100, making them top-tier choices for eco-conscious shoppers. Priced in the mid-range ($$), they offer exceptional value for sustainable stationery. Karst is a B Corp, Climate Neutral Certified, and donates 1% for the Planet. Michael Roger boasts FSC Certification, Global Recycled Standard, and also supports 1% for the Planet. While they share high ethical marks, their environmental focus areas and everyday usability differ significantly.Ethics difference
The main ethical distinction lies in their certifications and material sources. Karst prioritizes carbon neutrality and holistic sustainability as a B Corp, using stone paper (no trees, no water waste) and offsetting emissions. Michael Roger emphasizes recycled content and forest stewardship, with FSC-certified paper and Global Recycled Standard materials. Both give back via 1% for the Planet, but Karst’s portfolio is broader (climate + social), while Michael Roger targets circular economy and responsible forestry. If you value carbon footprint reduction, Karst edges ahead; if you prioritize recycled materials and forest protection, Michael Roger leads.Everyday use
In daily use, the Karst notebook features soft, smooth stone paper that is waterproof and tear-resistant—ideal for travelers or messy writers. Its A5 size is compact and fits most bags. The Michael Roger Decomposition Notebook offers classic lined or dot grid pages with a decomposed, rustic feel. The paper is slightly textured and recyclable, but not waterproof. For durability and unique writing experience, Karst stands out. For traditional notebook lovers who enjoy a natural paper texture and journaling aesthetic, Michael Roger is the familiar choice.Value
Both are $$ priced, but value depends on priorities. Karst’s stone paper lasts longer, resists damage, and supports a cradle-to-cradle model, justifying the cost for long-term users. Michael Roger offers lower upfront environmental impact through recycled content and FSC certification, but its paper is more conventional and may not endure as long. For those seeking a notebook that endures wear and tear, Karst offers better value. For budget-friendly eco-staples with a classical feel, Michael Roger is strong.Bottom line
This is a tough tie given identical ethics scores. However, the winner is **a** (Karst) for its broader impact (B Corp, Climate Neutral, stone paper innovation) and exceptional durability. Michael Roger is a close second, perfect for traditionalists seeking recycled and FSC materials.
