As the world looks toward the 2030 Winter Olympics in France, the event faces a critical question: can mega-events become regenerative forces for people and planet, rather than environmental burdens? Against a backdrop of climate uncertainty, public skepticism, and ecological fragility, this interactive workshop invites participants to explore how sustainability can be applied in practical and actionable ways through the lens of a global sporting event.

Through collaborative group work and co-creation, participants will identify the key challenges and opportunities of hosting a responsible Olympics. Using bloomUp’s Biodiversity Compass as a guide, they will explore how to balance ecological, social, and economic priorities. Working across themes such as energy, transport, materials, food, and nature, each group will design a 2030 Sustainability Roadmap focused on practical actions, measurable impact, and shared responsibility.

Moving beyond awareness to empowerment, the workshop encourages participants to think systemically yet act locally: discovering how small, meaningful steps can collectively drive transformation toward more regenerative, resilient, and inspiring events and communities

We invite you to share a friendly moment of writing together, on the theme of sustainability. All types of writing (poetry, short stories, slam, theater, etc..) are welcomed. There is no need for prior writing skills; what matters is to write and if you are confortable to share your writing. The workshop takes place in two stages: firstly, the presentation of more specific writing themes. It is followed by 45 minutes of free writing. Afterwards, we will gather in a circle, for those who wish to share their texts to do so, and if feedback is desired, we will provide it. The workshop is accessible to people writing in French and English.

How can we design a mobility system that is sustainable, efficient, and fair?
In this interactive workshop, participants will take on this challenge through The Optimal Mobility Mix, a serious game exploring the complex trade-offs that shape our transport choices and urban futures.
Working in teams, players will design their own “mobility mix” — a combination of transport modes (public transit, cycling, walking, driving, etc.) that must balance several often conflicting goals: economic efficiency, emissions reduction, social inclusion, public health, and quality of urban life.
The game invites discussion, negotiation, and creativity as participants strive to find their version of an “optimal” solution. Engaging, collaborative, and thought-provoking, The Optimal Mobility Mix opens space for reflection and dialogue around the challenges of climate action and sustainable urban transition.
At the end of the session, each group will share its proposed mix and the reasoning behind it — highlighting how our mobility choices mirror our collective values and visions of the future.

Le jeu vidéo peut-il aider à changer notre rapport à l’environnement et agir pour un futur désirable ?

À l’heure où les questions environnementales sont omniprésentes, comment penser et repenser notre rapport au jeu vidéo, et plus largement au numérique ? Au sein même du jeu, comment la nature est-elle représentée, et en quoi la place qui lui est accordée nous renseigne-t-elle sur notre rapport problématique au vivant ?Durant cet atelier, vous explorerez les modèles environnementaux dominants de l’histoire du jeu vidéo. En effet, de nombreux jeux sont fondés sur la compétition et le cumul de ressources, selon un modèle dit « extractiviste ». Une fois ce modèle identifié, il s’agit de discuter d’une sélection de jeux qui le critiquent et qui proposent des alternatives.Il est ainsi proposé d’explorer une lecture politique donnée aux questions écologiques dans les jeux vidéo. Pour ce faire, divers univers vidéoludiques mettant en scène notre rapport au vivant et à ce qui nous entoure seront abordés, tout en réfléchissant aux registres d’actions usuellement déployées au travers des avatars. Parmi les jeux discutés durant l’atelier (liste indicative)Final Fantasy 7 (1997), Endling (2022), Death Stranding (2020), Pokemon Go (2016), Lichenia (2019), Far, Lone Sails (2019)Un atelier proposé par L’éprouvette / Laboratoire Sciences et Société / Unil et le Gamelab-Lausanne
