The growing importance of sustainability in IT systems and software development, driven by new regulations and strategic business goals, shows that sustainability requirements should be addressed early in the IT solution development process to be truly impactful. Enterprise Architecture (EA), which operates at the strategic level of IT planning, plays a key role in aligning long-term business and IT strategies. Our work builds on a set of published enterprise principles. Through a collaborative process, we developed and articulated eight sustainability-oriented EA principles, drawing on expert experience. These principles aim to provide actionable guidance for architects seeking to align IT landscapes with environmental sustainability objectives.
