For over 10 years, the olive oil sector has been largely studied through Life Cycle Assessment (LCA). Thus, a review of the numerous results and the different evaluated scenarios is relevant for future LCA studies on this important agro-economic sector of the Mediterranean region.The herein present work, based on scientific and technical literature aims to compare system boundaries, functional units, life cycle inventories, allocation, impact assessments, and interpretations from the currently existing LCAs of olive oil. Furthermore, an analysis of the assessment of biogenic carbon has been carried out among the reviewed papers.As a result, 23 relevant LCA studies on olive oil production or olives cultivation (for olive oil production) were identified. Analysis of the literature converged on an unequivocal environmental hotspot, the agricultural phase; which represents the most impactful phase of the olive oil life cycle, due in particular to fertilisation, pesticides treatment, and irrigation. Waste management and distribution also appear to represent a crucial issue. The comparison work made on climate change impact assessment is on the order of magnitude of 460 kg CO 2 -eq/ton of olive and 1.6 kg CO 2 -eq/L of olive oil. This study highlights the complexity of carrying out an LCA on the olive oil sector. At last, best practices and methodological recommendations were matured.

International audienceThe chemical product substitution process is undertaken by chemical industries for complying with regulations, like REACH in Europe. Initially devoted to chemists, chemicals substitution is nowadays a complex process involving corporate, business and engineering stakeholders across the chemical enterprise for orienting the search toward a sustainable solution. We formalize a decision making process framework dedicated to the sustainable chemical product design activity in an industrial context. The framework aims at improving the sharing of information and knowledge and at enabling a collaborative work across the chemical enterprise stakeholders at the strategic, tactical and operational levels. It is supported by information and communication technologies (ICT) and integrates a computer aided molecular design tool. During the initial intelligence phase, a systemic analysis of the needs and usages enables to define the product requirements. In the design phase, they are compiled with the help of a facilitator to generate the input file of a computer aided product design tool. This multiobjective tool is designed to find mixtures with molecular fragments issued from renewable raw materials, and is able to handle environment-health and safety related properties along with process physicochemical properties. The final choice phase discusses the solution relevancy and provides feedback, before launching the product manufacturing. The framework is illustrated by the search of a bio-sourced water-solvent mixture formulation for lithographic blanket wash used in printing industry. The sustainability of the solution is assessed by using the sustainability shades metho
