The system dynamics simulation model in STELLA environment depicts the impact of digital technology attributes on the pillars of sustainability - Society, Environment and Business. The model of flow and resource interaction based on the system of differential equations allows to find out the critical attributes of technology and the dominant influence Triple Bottom Line (TBL) pillar. All links are assigned neutral values, so the modelling results are mainly influenced by the structure of the model. The model's audience can be technology sustainability researchers as well as digital technology authors and investors.
