An oceanography lab in its journey toward temperance

The current ecological crisis requires changes in our way to make science in order to reduce the ecological footprint of scientific research activities. This is particularly crucial for setting a good example for the rest of society. Here we present the process engaged by an oceanography laboratory to reduce its environmental footprint. Using a tool developed by the French collective Labos 1point5, we calculated the carbon footprint of our laboratory separated by activities (missions, consumables, buildings, campaigns at sea, etc.). This exercise allows us first of all to quantify the contribution of the various components of our scientific activity. It also shows that the environmental footprint of our scientific activities is significant, and that it needs to be taken seriously by the community studying the Earth system. Reducing this footprint highlights different possible scales of action. Some actions involve internal laboratory processes, while others require broader societal changes. The measures implemented by our laboratory members to minimize our activities' impact will be presented, representing a part of a broader initiative under Labos 1point5.
