Decarbonizing research laboratories? The tensions associated with the commensurability of carbon and how it opens up the boundaries of responsibility attribution

This article addresses the decarbonization of the French public research sector via a novel form of scientific mobilization: Labos 1point5, a group of research personnel, whose strategy is partly based on developing and then distributing a carbon calculator to estimate the quantity of greenhouse gases emitted by French public research laboratories, expressed as carbon dioxide equivalent (CO_2e) or “carbon footprint.” Here, I question the effects of this quantification on laboratories’ approach to decarbonization. Commensuration of research practices through an estimation that is not centered on a specific practice (such as travel) or limited to certain instruments (e.g., telescopes, supercomputers, computer hardware) opens up the boundaries of responsibility attribution. I identify three forms of tensions that arise during this process: a tension in terms of level of responsibilities, a material and disciplinary tension, and finally, a definitional tension, in the sense of “boundary-work” (Gieryn, 1983), in which this initiative is simultaneously labeled as scientific and activist.
