2.2 Environmental Evaluation of Green Packaging (LCA) Life Cycle Assessment (LCA) is widely used in academic and industrial research to quantify the environmental impacts of packaging solutions, including greenhouse gas emissions, energy use, and resource depletion. LCA enables comparison of conventional versus sustainable packaging systems by considering impacts throughout a product’s life cycle—from raw material extraction through manufacturing, logistics, use, and disposal.

Environmental Evaluation of Green Packaging Through Life Cycle Assessment Life Cycle Assessment has emerged as a cornerstone methodology in both academic research institutions and industrial settings for measuring and understanding the comprehensive environmental footprint of packaging solutions. This analytical framework provides researchers and manufacturers with the tools to quantify multiple environmental impact categories, including the release of greenhouse gases into the atmosphere, total energy consumption across all processes, and the depletion of natural resources such as minerals, water, and fossil fuels. What makes LCA particularly valuable in the packaging industry is its ability to facilitate meaningful comparisons between traditional packaging systems and their more sustainable alternatives. Rather than focusing on isolated aspects of environmental performance, this assessment approach takes a holistic view that tracks environmental impacts across every stage of a product's complete life journey. This comprehensive evaluation begins with the initial extraction of raw materials from the earth, continues through the complex manufacturing processes that transform these materials into finished packaging products, extends through the logistics networks that distribute these products to end users, encompasses the actual use phase where consumers interact with the packaging, and concludes with the final disposal or recycling processes that determine the packaging's end-of-life environmental impact.
