(1) First and foremost, we need an immediate fossil fuel phase-out. Digital policies, new digital research fields and economic interests should not obscure this political necessity. Similarly, nuclear energy is not a clean energy source and no alternative to fossil-based energy production. A sustainable digitalization can only be based on efficient, clean, fair, accessible, decentralized renewable energies.
(2) National, regional and global strategies to decrease the energy use of IT and communication technology are urgently needed. Political decision-makers have to push for this and implement effective legislation. For Europe, one element would be the extension of the EU ecodesign directive and energy efficiency labeling. The reform of the EU Energy Labeling Directive has to include to the energy label additional criteria such as life span, reparability, and access to spare parts. Future regulation should prohibit glued-in batteries or accumulators in electronic devises in order to ensure users to freely and autonomously replace them. Lack of repairability and free exchange of spare parts should be clearly defined and labeled as a construction flaw.
(3) The interlinkage between decentralized renewable energies and decentralized internet infrastructure should be supported and expanded.
(4) Big IT companies carry a social, ecological and economical responsibility to fight climate change. IT companies have to move to 100% renewable energy, improve their energy efficiency and transparently disclose the source of their energy supply.
