A preprint uploaded to arXiv (arXiv:2603.25772v1) by the French Society for Astronomy & Astrophysics (SF2A) Environmental Transition Commission shares selected results from a repeated survey tracking how French astronomy and astrophysics research has responded to the environmental crisis between 2019 and 2024. The survey was launched in 2019 by the 'Environnement-Transition' group at IRAP under P. Martin and updated in 2024 by the CNRS INSU-AA prospective working group led by S. Bontemp. The commission then collected responses from French institutes, sorted them, and extracted preliminary findings; the complete dataset will appear in a final CNRS report at the end of 2025.

Methodologically, this was a questionnaire-based survey distributed across French astronomy institutes. The preprint does not disclose the exact sample size, number of respondents, or response rate, which constitutes a notable limitation and raises the possibility of self-selection bias toward institutions already concerned about sustainability. As an arXiv preprint, the work has not been peer-reviewed and should be treated as preliminary rather than definitive.

The results reveal growing awareness of the field's environmental footprint, especially emissions from international air travel to conferences and observing runs, electricity-intensive high-performance computing for simulations and data reduction, and the operation of observatories. Researchers report increasing internal discussions yet struggle to translate concern into reduced impact.

This French effort mirrors and connects to wider patterns in the scientific community. A 2020 study on academic air travel (published in the Journal of Sustainable Tourism) documented that conference flying often accounts for the majority of individual researchers' carbon budgets, while a 2021 analysis in Nature Climate Change on institutional research footprints emphasized that computing and travel dominate emissions across disciplines. Post-COVID analyses of virtual conferences in astronomy further showed that digital formats can maintain scientific output while slashing travel emissions by 50-90%.

The original source and much of the limited coverage miss the deeper structural tension: funding and evaluation systems still reward international visibility and in-person networking, creating perverse incentives against meaningful decarbonization. The survey also under-explores the irony that astronomy's study of planetary atmospheres and habitability directly informs climate science, yet the field itself contributes to the problem it helps diagnose. What remains under-covered is the potential for astronomy's data-processing expertise to be redirected toward optimizing renewable energy systems or climate modeling.

Synthesizing these sources reveals a consistent pattern across European and global research: voluntary individual actions are insufficient without policy-level interventions such as carbon budgets attached to grants, mandatory virtual-first conferences, and investment in shared low-energy computing infrastructure. The French survey stands out for its longitudinal approach over five years, yet its limitations highlight the need for more transparent, quantified, and peer-reviewed studies that include response rates and full sectoral comparisons.

Ultimately, this work illuminates an under-reported conflict between the drive for scientific progress and climate responsibility. Greening research is no longer a peripheral concern but a central test of whether science can align its methods with its mission.
