Ecotoxicity is a key issue in environmental food labelling, especially under growing scrutiny from consumers and NGOs. In agriculture, concerns around the impacts of Plant Protection Products (PPPs) are increasing. Yet, Life Cycle Assessment (LCA) faces major limitations in evaluating ecotoxicity: both Life Cycle Inventories (LCIs) and Life Cycle Impact Assessment (LCIA) methods often lack consistent, specific, and up-to-date data for agricultural production. Updating agricultural LCIs remains time-consuming and costly, while farming practices are evolving rapidly in response to regulatory, technological, and climate-related changes.

This project aims to fill the inventory data gaps concerning substances used in agriculture. Our objectives are to improve the accuracy and temporal representativeness of LCIs for PPPs in French agricultural systems, and to assess the coverage and shortcomings of existing LCIA methods regarding the ecotoxicity of active substances.
