WILIAM – Within Limits Integrated Assessment Model

The WILIAM model (Within Limits Integrated Assessment Model) is a new IAM in the final stage of development within the H2020-LOCOMOTION project. WILIAM is a system dynamics developed model that has been designed based on MEDEAS models to address constraints in the field of IAMs. System dynamics allows capturing complex feedback loops and non-linear relationships between social, economic and environmental variables. WILIAM is composed of 8 modules: (1) demography, (2) society, (3) economy, (4) finance, (5) energy, (6) materials, (7) land and water, and (8) climate.

WILIAM starts simulating in 2005 and generally simulates until 2060, although the simulation horizon can be extended to 2100. WILIAM is a multi-regional model developed for 9 regions (EU27, UK, USMCA, China, Russia, India, EASOC, LATAM and LROW).

The ultimate goal is to apply WILIAM to explore thesocial, economic and environmental implications of long-term socio-ecological transition pathways at both global and regional scales, taking into account planetary boundaries as well as socio-economic constraints. The validation of the models has been carried out following several of the usual model validation procedures in system dynamics.
