What is one of the biggest challenges when conducting a robust LCA?

Gathering accurate and up-to-date data is indeed one of the most significant challenges when conducting a robust Life Cycle Assessment (LCA). The integrity and credibility of an LCA heavily rely on the quality of data collected throughout the life cycle of the product or process being assessed. Accurate and current data ensure that the assessment reflects true environmental impacts, from extraction of raw materials through production, use, and end-of-life disposal.

Additionally, the complexity of products and processes often means that data needs to be collected from various sources, which can vary widely in reliability and availability. In many cases, data may not be easily accessible, especially for products that involve diverse materials or complex supply chains. Any gaps or inaccuracies in this data can lead to misleading results, which can ultimately affect decision-making regarding product design, policy-making, and sustainability efforts. Thus, having comprehensive, accurate, and timely data is crucial for the success and reliability of an LCA.
