i-Dave: Data-Knowledge Integration to improve the reliability of LCA projets in the enterprise of the future

Published on June 12, 2025 Updated on April 17, 2026
The objective of the i-DAVE project is to propose a knowledge-based and AI-based framework, interoperable in a PLM approach, for the reliability of LCA/ECP studies. This is a dual decision-making aid: 1) Upstream of LCA studies to make the input data robust and configure the LCA/PCF study parameters. 2) Downstream for the exploitation of study results in the definition of the best action plans to reduce the PCF footprint.

Despite the growing interest in life cycle assessment (LCA) and product carbon footprint (PCF) methods and tools, their application faces three challenges:

  • data collection
  • the selection of relevant cost centers
  • the robustness of reference databases.

These challenges are very difficult because experts mastering the industrial process do not necessarily have the LCA/PCF culture. In addition, validating and aggregating all factors is a very complex activity because the data is collected from very heterogeneous sources, in varied business contexts and life phases. Current collection methods remain mostly manual, based on questionnaires, and dedicated tools are often disconnected from the company's overall digital chain. These issues are more critical in the case of long-life systems.

Once the studies are completed, another challenge concerns the exploitation of the results for the prediction of carbon trajectories. 

The concept

These challenges are expected to be addressed through three complementary solutions:
 

  • A central knowledge base defined as an ontology of the LCA/ECP domain and coupled with an inference engine that implements business rules to meet specific support requirements, such as the selection of scope and environmental cost centres, etc. This also involves supporting process traceability and the characterisation of systems in terms of LCA/ECP factors,
  • Intelligent connectors to ensure the interoperability of LCA/ECP tools with the various modules of the company’s digital chain for the extraction of data from heterogeneous sources. The Product Lifecycle Management (PLM) approach will be used to ensure the cross-functional integration of all types of information systems and databases relevant to LCA/ECP studies.
  • A tool for managing low-carbon strategies within the company, coupled with innovative dashboards. In particular, this tool contains algorithms for predicting future trajectories based on historical data, and classification algorithms to assist in selecting the best operational alternatives that generate the lowest carbon emissions. This module is based on a behavioural model containing useful performance indicators and cause-and-effect relationships between process parameters and environmental impacts.
Method

Scientific challenges

Understanding the most significant factors in terms of carbon impacts and the cause-and-effect relationships between organisational processes and environmental indicators. This presents a genuine scientific challenge due to the scope of the life cycle and the diversity of practices and specific cases within the field.


Data modelling amounts to building a unifying framework for a multitude of heterogeneous and fragmented databases spread across multiple sources. This leads to the problem of managing large volumes and a wide variety of data, much of which is difficult to access at its original sources.


Integrating LCA/ECP solutions into the company’s digital workflow introduces additional complexity due to the diversity of data formats and standards, which are not fully accounted for in current standards.


Human-machine interaction, both methodologically and in terms of information, is a key factor in the success or failure of LCA/ECP studies. This applies both upstream, when collecting data from experts, and downstream, when presenting results in a format suited to users’ expectations and profiles

  • Intelligent connectors to ensure the interoperability of LCA/PCF tools with the different modules of the company's digital chain for extracting data from heterogeneous sources. The Product Lifecycle Management (PLM) approach will be used to ensure the cross-functional integration of all types of information systems and databases useful for LCA/PCF studies.
  • A tool for managing low-carbon strategies in companies coupled with innovative dashboards. This tool contains in particular algorithms for predicting future trajectories based on history, and classification algorithms to help choose the best operational alternatives generating the minimum carbon emission impact. This module is based on a behavioral model containing useful performance indicators and cause-effect relationships between process parameters and environmental impacts.
