Brakes and leverages for reducing the environmental impact of laboratory animal facilities: A case study at the Institut Pasteur.

The Institut Pasteur has set the ambition to encourage all staff to get involved in sustainable development across all departments on campus. The animal facility staff joined the efforts of the sustainable development department to analyse current and future processes and identify potential solutions and related brakes and leverages for the reduction of the animal facilities' environmental impact. The first step was to collect the managers' experience on the local initiatives. Then, the managers attended a workshop to share information on networks and initiatives relevant to the topic and community, and to discuss the use of consumables, including personal protective equipment, single use plastics, bedding, feed, water, chemicals, and waste management. On the topics of interest, local initiatives were specifically detailed to assess their eventual implementation in all the institute's animal facilities, and tasks were set to pursue the managers' efforts in the longer term. A scenario was used to teach how to compare the carbon footprints of washing and disinfection equipment and process and to decide on the design of an animal facility. Finally, a summary is drawn of the brakes and leverages for the reduction of the environmental impact of the institute's animal facilities.
