The use of EcoTerra® technology reduces CO₂ emissions by 15 % to 80 % per square meter. This varies not least depending on the individual logistics and production conditions. We calculate the individual Carbon Foodprint according to EPD (DIN EN 15804+A2 & ISO 14025 / ISO 21930). The smaller the circle the larger the CO₂ reduction.
