The 29-31th of March, the University of Valladolid (UVa) welcomed the LOCOMOTION consortium in Valladolid for an in person modelling workshop. It was a great opportunity to progress on the modelling activities and to share knowledge, developments, opinions and perspectives from the different disciplines covered in the different Work Packages (economy, finance, energy and technology, environment, climate and also society). These face-to-face modelling workshops are key to develop a real consistent integrated framework for our WILIAM Integrated Assessment Model. During these three days of meetings, it was possible to solve common modelling questions including good practices in the use of the modelling software, repositories and data management and the requirements of the final LOCOMOTION tools. In addition, there was also free time in which we enjoyed a great social time including a visit of a winery and wine tasting.
