Effective data management and data interpretation are essential prerequisites for conducting robust and decision-relevant Life Cycle Assessment (LCA) studies, particularly within large and complex organisations. This presentation draws on experiences from a PhD project in which an organisation-wide consequential LCA was conducted...

Power-to-Gas technologies that convert CO₂ into renewable biomethane are attracting increasing interest as routes for long-term energy storage, carbon valorisation, and decarbonisation of the gas grid. Among them, electromethanogenesis, where electrotrophic methanogenic archaea reduce CO₂ to CH₄ at a biocathode driven by renewable electricity, is a promising but highly coupled...

Highlights / Discussion Points:

• LLMs can support automated unit process mapping pipelines
• Open-source language models can be fine-tuned to case specific knowledge bases
• These models can be efficiently implemented to open-source software such as Brightway2
• Language model driven methodologies require rigorous validation methods and metrics

**Concise...

Highlights and Discussion Points
- Facilitating a model-based integration of Life Cycle Assessments into early product development
- Supporting the transferability of the LCA method based on an open-source, Brightway-based software tool
- Incorporating uncertainties caused by lack of data and low system knowledge to prevent unaware design choices
- Providing a comprehensible way of...
