Our aim is to develop characterization factors, whose value, expressed in ecosystem services per unit area of land use, should depict the potential loss or gain of ecosystem services associated with the expansion of productive areas supporting good or service life cycles.
Life Cycle Assessment (LCA) is the overarching environmental accounting framework that we wish to enrich by adding ecosystem services as an impact category. LCA is a well-framed methodology standardized under the 2006 ISO norms (<link https: www.iso.org standard>ISO 14040-<link https: www.iso.org standard>ISO 14044), and is based on four methodological stages > <link http: eplca.jrc.ec.europa.eu>The methodology of LCA:
Two stages are of interest to us:
In order to reach our aim, we use the Multi-scale Integrated Models of Ecosystem Services (MIMES), coupled with techniques of:
This dynamic and multi-scale integrated model allows to evaluate the changes in ES provision induced by different scenarios of development over time and space, and at multiple scales (e.g. municipal, national, global).

More specifically, and taking as a scenario the use of land by production systems, in VALUES we wish to couple:
Accordingly, we wish to evaluate the impact of expanding different land use types (from the CORINE classification system and according to their implementation in life cycle inventory databases such as ecoinvent v3) on the pollination of crops and the sequestration of carbon worldwide and at the scale of Luxembourg.
The results obtained from this modelling exercise are tested over a case-study focusing on the implementation and production of biofuels in Luxembourg in the frame of a previously <link https: www.list.lu en research project musa>FNR CORE funded project.
