Sustainable transport

The CTE encourages the use of sustainable transport. To this end, it has provided the laboratory’s staff with bicycles since 2024 for professional trips.
Whether getting to a teaching location, attending an off-site meeting, going to an event, or heading out for lunch, bicycles can easily replace cars. Taken together, all these short trips can make a real difference.

Five bicycles are available for staff to reserve, complete with all the necessary equipment. As the IMS laboratory is spread across three university buildings, these bikes also help to maintain connections between the different IMS sites, while being environmentally friendly.

If you are a member of the laboratory, reservations can be made on the IMS intranet.

Clean Up Day

The Clean Up Day is an annual event, taking place in spring, during which all teams are invited to sort through items that are no longer used or cluttering up the laboratory. Everyone is then free to help themselves and give a second life to the items made available (furniture, decorations, IT and electronic equipment, boxes, glassware, etc.) either within the laboratory itself or elsewhere. Local associations are also welcome to collect anything that might be useful to them. The remaining items are taken to the waste collection center to be recycled appropriately.

This initiative has been running since 2022. It is paired with the Transition Morning, in partnership with the Institute for Transitions at the University of Bordeaux. This friendly gathering provides an opportunity to present and review the CTE’s actions. Fun workshops are also offered, such as serious games to raise awareness or a questionnaire to calculate one’s personal carbon footprint.
The event concludes with a vegetarian buffet.

Awareness workshops

The CTE helps raise awareness among IMS staff about the climate emergency by actively promoting events organized by the University of Bordeaux or within Bordeaux Métropole. In addition, its members regularly host workshops for all staff.

The Climate Fresk is an educational tool that enables the rapid and widespread understanding of climate change issues. In the form of a serious game combining reflection and creativity, participants discover ways to take concrete actions. Several members of the CTE have been trained by the Climate Fresk association in facilitating and implementing this collective intelligence workshop.

The Digital Collage is a fun and collaborative workshop that focuses specifically on the environmental challenges of digital technology. Its teaching approach, similar to that of the Climate Fresk, and its commitment to more sustainable digital practices are particularly well suited to the research conducted at IMS.

Carbon footprint

The CTE has conducted the laboratory’s greenhouse gas emissions (GHG) inventory since 2023 using the GES 1point5 tool developed by the French collective Labos 1point5.

This meticulous work is based, among other things, on questionnaires sent to each member of the staff to learn about their habits at work. It is important to include all teams in the process; everyone has a role to play!

To take this further, the CTE also compared the GHG inventory data with predictions from a web application called ResearchCarbonRef, developed by Léa Marquet as part of her thesis: “The carbon footprint of public scientific research: typology, determinants, and trade-offs” at the UMR Innovation, Montpellier.

This application uses several predictive models (one per emission source) to estimate the average emissions per staff member for each of these sources. It takes into account the structural characteristics of the research unit in question (supervisory bodies, disciplines, number and distribution of staff, uses, budgets, geographical location, etc.) but does not compare research units directly with each other.

More information in the following article « Setting reference GHG emissions for research activities », Marquet et al. (2025), Journal of Cleaner Production.

In 2024, the IMS laboratory’s GHG emissions were very close to predictions for Electricity. They were below predictions for Heating and Commutes. However, they exceeded predictions for Travels (business trips) and Purchases. This assessment enables the CTE to guide and focus the laboratory’s actions.

Note: The quantile intervals for the emission sources Travels, Commutes, Electricity, and Heating, obtained by Random Forest, cannot be compared to the confidence intervals for the source Purchases, obtained by linear regression.

CTE Members

The CTE welcomes all IMS members, whether permanent or non-permanent, regardless of their research group or department. It also works in collaboration with external stakeholders from the University of Bordeaux.
