Abstracts

Architecting Carbon-Aware Software-as-a-Service – Samuele Giussani
Software-as-a-Service (SaaS) solutions are increasingly adopted due to their scalability, cost-effectiveness, and ability to support rapid deployment while ensuring high availability and flexibility. However, carbon emissions are still rarely treated as a first-class design concern. Existing approaches predominantly focus on post-deployment measurement and mitigation, overlooking the fact that architectural decisions determine a significant share of a system’s environmental impact. This is particularly evident in multi-region and multi-tenant settings, where carbon intensity varies across locations and over time, and tenants contribute unevenly to overall resource consumption. Supporting architects in evaluating these factors early in the design process requires systematic reasoning mechanisms that can combine heterogeneous architectural, infrastructural, and operational information into actionable insights.

In this talk, the conceptual foundations of a Carbon-Aware Reasoning Framework are presented, enabling the design-time evaluation of multi-tenant SaaS architectures with respect to both carbon impact and performance-related quality attributes. A model-driven, tool-supported implementation of the Framework is then introduced, illustrating how carbon-aware reasoning can complement traditional architectural evaluation practices and inform environmentally conscious deployment decisions.

Digital product passports: A value perspective – Timmy Öberg
This presentation provides insights into an ongoing systematic mapping review of digital product passports (DPPs) from a value and ecosystem perspective. Based on existing and emerging classification schemes, the presentation maps the DPP research landscape and discusses current trends. The study explores where current DPP research is focused, including publication venues, research methods, contribution types, and industry sectors. It further analyzes the value dimensions the literature address, including value outcomes, value creation capabilities, and the value chain actors considered.
