@ARTICLE{TBA, TITLE={[FORTHCOMING] Decarbonation modes and ecological transition}, AUTHOR={Smaïl AÏT EL HADJ, }, JOURNAL={Technology and Innovation}, VOLUME={}, NUMBER={Forthcoming papers}, YEAR={2025}, URL={https://www.openscience.fr/Decarbonation-modes-and-ecological-transition}, DOI={TBA}, ISSN={2399-8571}, ABSTRACT={This article presents, with an explicit angle on decarbonisation, the research that we carried out in the book: Ecological Transition and Technological Change, ISTE Volume 42, London 2024.The article highlights and describes three main decarbonisation paths, corresponding to three ecological transition issues: decarbonization as mitigation through capture and storage of emitted C02 with an unchanged technical and economic system; decarbonization as a solution to the ecological transition matter, centred on technological mutation, introducing decarbonised technologies as a replacement of fossil-fuel-based technologies, mainly combustion technologies. Finally, in view of the difficulty of achieving a satisfactory level of decarbonization, a third ecological transition issue is taking shape, namely the reorganization of our production, consumption and transport patterns, based essentially on sobriety and a reduction in the level of activity. The importance of the challenge means that these three decarbonization systems will continue to work in synergy.}}
