GRETA tool

What is GRETA?

GRETA is a digital assessment and decision-support tool that helps companies evaluate and improve the environmental sustainability of products, processes, and circular strategies. Based on Life Cycle Assessment (LCA) principles, GRETA enables the comparison of alternative scenarios (e.g. AS-IS vs TO-BE) and the calculation of key environmental indicators across the product life cycle. The tool supports structured data collection and translates assessment results into clear, actionable insights to support informed, data-driven decision-making. This video provides a high-level introduction to GRETA and its core functionalities.

GRETA supports early-stage decision-making by assessing products and processes, comparing scenarios, and generating reports. The tool is integrated with the RAMP platform and can exchange data via APIs and near-real-time sources such as IoT devices, databases, and external systems.

GRETA: Plastic Pilot Environmental Assessment and Decision Support

This training video demonstrates the application of GRETA within the Plastic Pilot of the CIRCULOOS project. The use case focuses on the production of a washing machine dispenser manufactured through injection moulding and compares two alternative scenarios: a conventional linear model based on virgin plastics and a circular model that incorporates production scrap back into the manufacturing process.

The video provides a step-by-step walkthrough of the assessment workflow in GRETA, including modelling life-cycle stages, executing environmental assessments, hotspot identification, contribution analysis, and scenario comparison. Particular attention is given to evaluating different recycled-content configurations and identifying environmental trade-offs associated with circular production strategies.

By the end of the tutorial, users will understand how GRETA can support data-driven decision-making, eco-design activities, and the optimisation of recycled material content by comparing alternative production scenarios using the Environmental Footprint 3.1 methodology.
