"The current trend for digital overconsumption in the world is not sustainable with respect to the supply of energy and materials it requires. Digital transition as it is implemented at present results from a considerable expansion of the direct energy footprint of digital technologies, with an annual growth of from 9% to 10% according to the different hypotheses. This hyper-growth, occurring in spite of regular advances made up to now in the energy efficiency of digital devices and systems, is resulting in: The appropriation of a progressively disproportionate share of available electricity, increasing tension on the buildup of non-carbon production sources; The increase by half in 5 years of digital technology in GHG emissions (2.5% to 3.7% between 2013 and 2018) and a twofold increase of this ratio from now to 2025 (if data traffic continues to grow by 30% a year); Increasing demand for rare and critical metals of which many are essential for low carbon energy technologies, hence a risk of tension regarding supplies, exacerbated by the almost monopolistic position of China with respect to most of these metals [.] So that digital transition can contribute to reducing the global energy consumption of a system, it is vital to change our consumption patterns and integrating digital technology in our projects, by applying the following recommendations: 1. Adopt digital sobriety as a principle of action; 2. Inform and spread awareness; 3. Mobilize the lever of public purchasing; 4. Allow companies and organizations to manage the environmental dimension of their digital transition; 5. Carry out a carbon balance of digital projects to facilitate their prioritization; 6. Improve consideration of the systemic dimensions of digital technology; 7. Work at the European scale and with international organizations." (Conclusions, page 60-63)
