Life cycle assessment (LCA) is a comprehensive method used to evaluate the environmental impacts of a product or service throughout its entire life cycle, from raw material extraction to disposal.

This assessment takes into account all stages of the product's life, including manufacturing, transportation, use, and end-of-life processes. An example of a life cycle assessment could be conducted for a smartphone.

The assessment would consider the extraction of raw materials such as metals and minerals, the manufacturing process, the transportation of components to assembly plants, the use phase of the smartphone by consumers, and the eventual disposal or recycling of the device. By conducting a life cycle assessment, companies can gain valuable insights into the environmental impacts of their products and identify opportunities to reduce their carbon footprint and improve sustainability.

This information can be used to make informed decisions about product design, sourcing materials, manufacturing processes, and waste management practices. Overall, life cycle assessment provides a holistic view of the environmental impacts of a product or service, allowing companies to make more sustainable choices and reduce their overall environmental footprint.

It is a powerful tool for businesses looking to improve their sustainability practices and meet the growing demand for environmentally-friendly products.
