The product Carbon Footprint relating to the life cycle of a pair of Steve's shoes is equal to 4.83 kg of CO2 eq. The materials, chosen through eco-design logic, with a high prevalence of nature-based bio polymers, have led to excellent results from the point of view of the environmental profile of the product. Exclusively through the use of vegan bio-leather produced from fruit processing by-products it is possible to reduce the impact of the product by 47% compared to animal leather. The other relevant element concerns the production phases and suppliers that are located exclusively within national borders. In this way, emissions related to transport are very low compared to the market standard. The impact benchmark* in terms of carbon footprint created on the basis of an analysis carried out by MIT (Massachusetts Institute of Technology) and an important European study gave an average impact value of 12.1 kg of CO2eq. This means that Steve's shoes have an impact in terms of emissions that is 60% lower than the market standard.
