Designing 4D-sustainable eservices is very complex, mainly due to the many challenges in communicating and assessing sustainability. This paper proposes a conceptual model that identifies the core elements of 4Dsustainable e-services. Our goal is to enhance the shared understanding amongst sustainability stakeholders, while easing sustainability assessment and negotiation. We illustrate the value of the conceptual model using a real-life case study featuring an airport baggage handling system.Text/Conference Paper
