Pourquoi faut-il aller au-delà des outils traditionnels ❓
Il est temps de dépasser les approches traditionnelles de la conception et du design et pour bâtir un futur véritablement soutenable. Contrairement aux pratiques classiques qui se contentent de limiter ou compenser les impacts environnementaux, DfSoSy adopte une approche proactive en intégrant les limites planétaires et la justice sociale au cœur des projets.
Les bénéfices de cette approche :
✅ Une prise en compte des écosystèmes dès la conception
✅ Un alignement avec les capacités régénératives de la planète
✅ Une transformation des modèles économiques et sociaux des entreprises et collectivités
Adopter cette approche, c'est réinventer notre façon d’innover et concevoir pour répondre aux défis écologiques et sociétaux actuels.

Fête de la science 2024
Les limites planétaires, un guide pour nos actions quotidiennes ! Ou comment devenir acteur dans la préservation de notre maison Terre !
Pour la 33e édition de la Fête de la Science, D-TechnoSS s'est engagé à l'Université de Technologie de Troyes pour sensibiliser le public aux enjeux cruciaux des limites planétaires.
FDS 2024 Ce fut l’occasion d’échanger avec des élèves du primaire, des collégiens, et des familles, tous curieux de découvrir les défis de notre planète !
Notre participation visait à faire connaître le concept des limites planétaires et à réfléchir, ensemble, sur l’impact de nos modes de consommation et de nos gestes quotidiens sur ces limites. Les participants ont pris conscience des habitudes qu'ils peuvent transformer pour réduire notre empreinte collective.
Au fil de l'atelier, le public a imaginé et partagé des actions, des solutions et des comportements durables pour un avenir plus soutenable. Sérieux dans le sujet mais avec une touche ludique, nous avons mis en place un espace d’équipe dynamique pour générer des idées et des actions simples, efficaces, et, surtout, réalisables au quotidien. Ensemble, nous avons semé les graines d’un futur écologique, où chacun peut devenir champion de la planète !
Cet atelier a été une formidable opportunité de mettre en lumière l'importance de sensibiliser la société civile aux enjeux de la transition socio-écologique.
On June 21, 2024, Mélissa Escobar, PhD candidate at the Institut Henri FAYOLEMSE and Valérie Laforest from the École des Mines de Saint-Étienne EMSE, both members of the D-TechnoSS, participated in the webinar: “Research & Responsible Digital Technology”, organized by Orange.
Orange Webinar This webinar brought together 40 participants from Orange and focused on the concept of strong sustainability, the research theme of the ANRD-TechnoSS project. Durint the spring, Orange invited researchers to present their scientific work on sobriety and strong sustainability.
For a sustainable transition, it is crucial to understand the interdependencies between society, the economy, and the environment. Strong sustainability affirms that natural resources and ecosystem services are irreplaceable, and social equity and economic prosperity must respect planetary boundaries. Industrial innovation is essential to achieve strong sustainability, and large companies in the ICT sector must adopt more sustainable production and consumption practices.
Mélissa Escobar and Valérie Laforest explained the different aspects of the strong sustainability approach and presented concrete examples of its application. These examples are intended to help participants take ownership of this approach by showing how it can be integrated into organizational and industrial strategies.
We thank Orange group, particularly Claire Gayan, Operational Manager of Research domains at Orange, and Marc Vautier, Referent of the Orange Energy & Environment Expertise community. This initiative represents an excellent opportunity for sharing and collaboration between research and industry to meet sustainability challenges.
“La Guinguette LowTech” Festival
On July 17, 2024, Valérie Laforest, member of D-TechnoSS, participated in the Festival “La Guinguette LowTech” organized by Orange the Association Halage.

We thank the organizers for promoting this type of activity that allows us to bring our work closer to local communities.
Disseminating our research project to the public is a priority. Melissa had the opportunity to perform twice in front of college students. The first was a "Make Your Games" evening. The aim was to increase public awareness of the climate catastrophe and its anthropogenic cause. Melissa used the "La fresque du Climat" tool on the Quiz version of her. The second intervention was carried out with students from Jules Valles College where Melissa presented her research work in order to raise awareness about the current climate catastroph
WEBINAR | Rebound effects
The S.mart network organized last November 10, 2022 from 12:15 p.m. to 1:45 p.m. the webinar entitled "Rebound effects: what are the scientific and operational challenges for the socio-ecological transition?"
This edition was animated and presented by:
Michal Kozderka – UNISTRA
Emmanuel Caillaud – CNAM
Lou-Lyne Leconte – member of D-TECHNOSS, PhD student URCA/UTT
Tatiana Reyes – member of D-TECHNOSS, UTT
Jean-Claude Boldrini – Nantes University
Webinar In this webinar, the evolutionary and plural nature of the concept is analyzed in order to present clues for reflection on its uptake and delimitation. Currently, there are several questions on the subject: Does a rebound effect only bring harmful consequences related to environmental issues? Or can these consequences also be beneficial and create value? What is the link between the rebound effect and the socio-ecological impact? How is it integrated into the design process? Is it necessarily unpredictable or can it be apprehended through models, methods, assessment tools or simulation? Should it be approached in a multidisciplinary or transdisciplinary way?
Within the D-TECHNOSS project, the concept of rebound effects is an important element to consider in the doctoral works of Lou-Lyne and Melissa. However, we believe that the study of this concept in other disciplines will allow a better understanding of all its implications.

Doctoriales 2022
The non-academic world (companies, local and regional authorities) offers PhDs numerous opportunities to develop their career.
Doctoriales Our doctoral student Lou-Lyne had the opportunity to participate in the 2022 Doctoral Programs organized by the UTT and the URCA. The event took place from October 24 to 27, 2022 at the Domaine de la Forêt d'Orient. During the event, a series of training courses related to the creation of startups were carried out (creativity, innovation, market research, intellectual property, budget, communication, technical feasibility, environmental impact, etc.). During 3.5 days the participants got acquainted with the world of entrepreneurship.
This event was an opportunity for Lou-Lyne to develop new softskills that can be valued in future job interviews. It was also a time for the creation of professional networks for integration into the socioeconomic world.
The EURAM 2022 doctoral colloquium was held on June 13 and 14, 2022 as a part of the EURAM international conference ““Leading the Digital Transformation” 2022.
EURAM With the article “Understanding of consumers’ behaviourstowards ecodesigned products and services”, Lou-Lyne presented a general description of his doctoral thesis whose objective is to understand consumer behavior towards eco-designed products and services. In his presentation, Lou-Lyne exposed the contributions of the scientific community on the notions of consumer, sustainable development, sustainability strong and ecodesign, as well as their interrelationships, to better understand the consumer implications of sustainable development and ecodesign approaches. Lou-Lyne finally proposes a model detailing the expected empirical results of the research.
This was an opportunity for Lou-Lyne to showcase his research and scholarly mission to different audiences; as well as connecting with an international network of academics and other beneficiaries and users of its research.
The 9th edition of the EcoSD doctoral training "Eco-design of complex systems", or EcoDoCS'2022. took place from Monday 10 to Friday 14 October 2022 on the CentraleSupélec campus (Gif-sur-Yvette). It is organized by EcoSD via CentraleSupélec, AgroParisTech and ISAE-Supméca, financed by EcoSD and S.mart, and supported by the Design Society.
ECOSD
The work of our doctoral student Melissa ESCOBAR on the development of design models for strong sustainability requires specific knowledge and skills. The purpose of this training was to help participants define the scientific and industrial issues of the eco-design of complex systems (products, services, factories, socio-technical systems) and to present practical solutions for modeling, simulating, optimizing and making decisions in conception phase. It alternates theory and practice on numerous case studies or workshops.
Melissa had the opportunity to reflect and discuss her own thesis work with the other participants. This training was also an opportunity to build collaborative links with other people interested in ecological issues and socio-ecological transitions.
Atelier 2022 Juin On June 24, 2022, in the city of Dijon, the D-TECHNOSS team held its seminar and reflection workshop on strong sustainability.
The seminar had as its central topic of discussion the definition of the concept of strong sustainability. The first part of our meeting was focused on analyzing the concept of strong sustainability. Strong sustainability is the main axis of our project and it is necessary to be able to concretize the way to make its definition operable.
The second part of our seminar focused on the advancement of our two PhD students, Lou-Lyne LECONTE and Melissa ESCOBAR. They presented us with their first results and their work plan for the coming months. Articulating two investigations from the human sciences and engineering in the D-TECHNOSS project allows a complete vision of the problem to be studied.
3ème Journée Marketing et Développement durable
On December 9, 2021, the 3ème Journée Marketing et Développement durable (JMDD) took place in Troyes in connection with the thematic interest group (GIT) of the French Marketing Association AFM and the Institute of Services and Industries of the Future of Troyes ISIFT . Lou-Lyne LECONTE, a doctoral student within the D-TECHNOSS project, presented a first part of the results of her doctoral thesis.
Lou - Lyne With the presentation entitled "CONSUMERS AND ECODESIGN: A LITERATURE REVIEW", Lou-Lyne addresses the relationships between consumers, sustainable development and ecodesign. This synthesis reveals the difficulties of definition and the limits inherent to sustainable development and ecodesign and, therefore, raises the need to rethink these notions. In her presentation, Lou-Lyne mentions that consumer expectations illustrate a growing concern for sustainable development. However, the role of the consumer in the proper use of eco-designed products and services does not seem to benefit from the necessary consideration during the design phase, thus generating rebound effects that can destroy the potential environmental gains achieved.
We invite you to read the complete publication of this presentation by clicking here.
