While research has shown that all human activities have an environmental footprint that needs to be leveraged down to ensure a liveable future, this basic premise is seldom applied to research activities themselves. In fact, the tools developed to assess the environmental impact of research are not as well known or widespread, even in sustainability sciences, as one could think. This has to do in part with the fact that we still lack established standards and measures that can serve as baselines. But it is also due to the fact that impact assessment and offsetting practices are embedded in national institutional structures which make their transfer in other Academic system an intercultural challenge. In this presentation, I will present some of these initiatives, in particular the labos1point5 tool, with the goal of facilitating its implementation in other national contexts. I will present the method as well as the results that could be gathered for different labs. Beyond the tools themselves, this paper will be an opportunity to discuss in a more fundamental way research practices as we know them, in particular those that pertain to Academic travel. To what extent do European research practices contribute to a system of global injustice, and how could changes towards more equitable and sustainable practices be initiated at institutional level?
