The global climate is experiencing a rapid and unprecedented warming trend. The ICT sector is a notable contributor to global greenhouse gas emissions, with its environmental impact continuing to expand. Addressing this issue is vital for achieving the objectives of the Paris Agreement, particularly the goal of limiting global temperature rise to 1.5°C. At the European Union level, regulatory measures such as the CSRD and the CSDD impose obligations on companies, including those within the ICT sector, to recognize and mitigate their environmental footprint. This study provides a comprehensive system mapping aimed at enhancing the awareness and understanding of software-related emissions and the corresponding responsibilities borne by the ICT sector. The mapping identifies the primary sources of carbon emissions and energy consumption within the ICT domain while also outlining the key responsibilities of the stakeholders accountable throughout the software lifecycle.
