We have calculated product-specific carbon footprints for 11 products so far. We selected four safety footwear models for comparison; they differ from each other especially in terms of the materials used. Raw materials explain the biggest differences in the carbon footprint of these products: leather footwear has a considerably larger carbon footprint than footwear made entirely of synthetic materials. Due to its durability, leather is, however, the best available material for safety footwear since leather footwear is thought to last approximately twice as long as footwear made of synthetic materials. Leather is, however, a significant factor in the climate impact of our products, which is why we are constantly researching alternative materials.
