Artificial Intelligence (AI) is transforming science, business, and sustainability assessment. In the field of Life Cycle Assessment (LCA), AI promises faster data generation, improved model quality, and advanced predictive capabilities — but also raises new questions about transparency, bias, and reproducibility. This LCA Forum will explore how machine learning, natural language processing (NLP), and large language models (LLMs) are reshaping LCA research and practice. We will discuss emerging applications, methodological challenges, data quality and its control and ethical considerations. We finally aim at outlining a roadmap for integrating AI into…
