One of the most effective tools for achieving sustainability is Life Cycle Assessment (LCA) —  a comprehensive methodology that evaluates the environmental impact of products and processes across their entire life cycle.

In this blog post, we explore the role of life cycle assessment for ethanol, real-world examples of companies leveraging LCA, and how this practice helps reduce carbon footprints and improve sustainability.

What is Life Cycle Assessment (LCA)

Life Cycle Assessment (LCA) is a systematic approach used to assess the environmental impact of a product, process, or service from cradle to grave. The process includes:

  • Raw material extraction: The sourcing of raw materials required for production.
  • Manufacturing: The energy, water, and raw material inputs during production.
  • Transportation: Emissions and energy consumption during distribution.
  • Use phase: How the product is consumed and its impact during use.
  • End-of-life: The disposal, recycling, or reuse of the product after its useful life.

The goal of LCA is to identify opportunities to minimize negative environmental impacts, reduce energy use, and improve resource efficiency throughout the product’s life cycle.

In the context of ethanol, LCA helps evaluate the sustainability of biofuels by comparing their environmental performance against traditional fuels.
