This research aims to implement the Life Cycle Assessment (LCA) methodology to the Environmental Impact Assessment (EIA) in the construction of a drivable trail in the district of Querobamba, province of Ayacucho, and compare the results with those obtained from the EIA initially conducted for the project's inception. To carry out this research, detailed data on CO2eq emissions, particulate matter, noise level, soil quality, water quality, flora, fauna, landscape, and employment in each phase of the project (planning, construction, and closure) were collected from the technical dossier. SimaPro software was used to calculate air emissions (CO2eq and particulate matter) generated by machinery and equipment used in the project based on the consumption of D2 diesel and 90-octane gasoline. Additionally, Impro4 impact indicators were employed to evaluate and quantify other environmental factors. Subsequently, a cause-effect matrix was developed to qualitatively assess each environmental factor in the project's executed items. With all the data obtained, the EIA09 program was used to perform quantitative and qualitative assessment of each project item, obtaining weighted values for each environmental impact generated. Then, the same calculation was performed using only the magnitude indices obtained from SimaPro and Impro4, applying the hybrid EIA to compare the values obtained by conducting only the EIA and the hybrid EIA. The results reveal that some project items generate greater pollution than anticipated, with air being the environmental factor with the most negative impact. It was observed that by applying the hybrid EIA, the weighted values obtained are much larger than those obtained using EIA09 but maintaining the sense of impact. This leads us to conclude that the importance index disturbs the result of an EIA by providing much lower magnitude values and making it appear that some project items have a lower impact than they do. It is concluded that the combination of EIA and LCA provides a more comprehensive view of environmental impacts, as it allows analyzing both immediate and indirect effects. This is crucial, as factors such as air and noise affect not only the immediate project surroundings but also broader areas that must be considered in the planning of mitigation measures. Finally, this study highlights the importance of integrating LCA into EIA for a more thorough and accurate assessment of environmental impacts in infrastructure construction projects, such as drivable trails. Furthermore, specific areas where environmental impacts are more significant than expected are identified, providing important data for future projects in similar areas.
