Summary of the Life Cycle Assessment (LCA) approach

Today, with the spread of negative environmental consequences such as acid rain, air pollution, global warming, soil erosion, water pollution and the effects of these consequences on human life and biodiversity, human awareness of the environment and its protection has increased. This has led to the interest of humans and environmental researchers to better understand the origin and consequences of environmental hazards (1399, Ahmadi Saeedabad, Fatemeh; Seyed Hassan Sharifi Pajaei and Ashkan Nabavi Pelesarai and Qasem Asadpour) also to achieve sustainable goals such as carbon reduction, participation. They must first examine their supply chain and business activities to identify the products or processes that are most influential. This is to ensure that the most cost-effective measures are selected to achieve the sustainability goal (Huang and Parry 2014). In recent decades, many tools for environmental assessments have evolved. One of the most popular and effective of these tools is the Life Cycle Assessment (LCA), which shows the negative effects of a system, product or service on the environment.
