This study carried out a Life Cycle Assessment (LCA) of the pork production process based on a detailed Life Cycle Inventory (LCI) of inputs and outputs of 3 years of the process, from the entrance of the live animal to the final packaged products. The Life Cycle Impact Analysis (LCIA) was carried out using the Environmental Footprint method to observe which impact categories are most relevant in environmental terms, excluding impacts related to production of the living animal. The results of the LCIA made it possible to identify the most relevant impact categories, such as Acidification, Climate change, Freshwater ecotoxicity, Freshwater and Marine eutrophication, Resource and Water use. The impacts detected supported the definition of critical Key Performance Indicators (KPI) and Process Performance Indicators (PPIs) in environmental aspects, establishing a cause-and-effect relationship with the organization's strategic objectives. A model for monitoring environmental impacts with established indicators was developed based on the LCA study of the pork processing. The proposed monitoring indicators were identified based on the environmental impacts and this industrial sector can utilize these findings to adopt a more sustainable process.
