SF2A Environmental Transition Commission: What kind of astrophysics research for a sustainable world?

During its annual conference in 2024, the French Society of Astronomy \& Astrophysics (SF2A) hosted, for the fourth time, a special session dedicated to discussing the environmental transition within the French astrophysics research community. This year had a special context: both the CNRS-INSU and the CNES were preparing their scientific perspectives for the period 2025-2030 in the field of Astronomy-Astrophysics (AA). In this proceeding, we first describe the main actions undertaken by the Commission Transition Environnementale. Then, we summarize the discussions held during the half-day workshop, which brought together about 100 participants, and point to forthcoming proceeding, reports and other related resources. A key message is that the French A\&A community is now fully aware that astronomical activities simply cannot thrive indefinitely in the current situation, and seems now eager to seize the opportunity of developing our profession towards a better social and environmental impact.
