This research addresses the growing issue of electronic waste (e-waste) and the environmental impact of the IT industry, which contributes up to 2.8% of global greenhouse gas emissions. The study focuses on developing a Decision Support System (DSS) to help European businesses manage IT hardware sustainably, in line with regulations like the European Green Deal. The DSS offers strategies for sustainable procurement, energy optimization, extending hardware lifespan, and responsible disposal, aiding businesses in reducing their environmental impact. The research also highlights the DSS's potential to promote circular economy principles and recommends further development for broader applicability.
