This report is the second deliverable of the WP9 “Technical coordination and quality assurance” LOCOMOTION project. The joint development of an IAM simulation model between various research groups requires a significant effort in technical coordination. The adoption of common rules and procedures for modelling and programming are essential for the effectiveness of work. Much work has been done in these lines since the publication of D9.1, such as regional disaggregation heterogeneity and units consistency, including also the development of specific new tools. Work has also advanced in WP8 with relation to the description of scenarios (storylines and policies selection) selected to be tested within the full WILIAM in the close future. But the focus of this deliverable is the current, interim, stage of the WILIAM model, taking as reference the modules which compose it: economy, finance, demography, society, land and water, climate, materials and energy. Here we report the interim synthesis of the model, selected results and scenario assessment, which is an intermediary step before the finalization and documentation of the finalized model in D9.3, where the key outcomes associated with the different scenarios resulting from the set of policies assessed will allow to derive a normative set of proposals to deal with low-carbon transition. WILIAM is being developed in a sequential way, from modules to full model, and from simpler to more complex structures in order to facilitate the progressive development, integration and validation of each of the modules which compose the whole model ; with benefits also for allowing the parallel development of Python translation and end-user interfaces. An overview of the current state of development of WILIAM by (sub)modules (or Gitlab branches) at the time of the submission of this report, achieved after 5 successive integrations achieved between May 2021 and November 2021. For each module it is reported (a) a short description of the module, (b) main equations, (c) module variables and parameters, (d) data sources and (e) validation & preliminary results. Attending to the current development stage, a selection of results is provided focusing on those more mature (sub)modules.
