Summary

The constantly changing state of the natural environment and the impacts of climate change have become increasingly noticeable in recent decades. To limit, and ideally eliminate, these impacts, a sustainable way of producing goods must be adopted.To enhance this effort, a new directive from the European Union has been introduced, that of Digital Product Passports (DPP). This Digital Product Passport contains details collected throughout the life cycle of a product or service.This thesis focuses on the study of DPPs. It analyzes how they are created, the elements that must be included in them, and the ways they are represented. Additionally, their advantages and the challenges that arise during their creation are presented. It is noted that, although their implementation is not yet mandatory, they are already applied to several products and services. Part of these is presented in this work.To demonstrate their usefulness, sustainability indicators—environmental, social, and economic—were sought and gathered. The purpose of the indicators is to quantify the overall sustainability of a product. These were calculated based on the data of an orange juice production industry, which secures all of its required electrical energy from fossil fuels. Subsequently, they were calculated three more times, increasing the percentage of renewable energy sources to 10%, 40%, and 70%. By gathering the results of these indicators, the increase in the sustainability of the system was analyzed.
