From June 23rd to 25th, the RE4GREEN project partners gathered in Bonn for a pivotal midterm meeting. Over the course of three days, participants reviewed progress, shared insights, and laid the groundwork for the coming phases of the project. The gathering fostered renewed collaboration and sparked productive discussions around future strategies. A central takeaway from the meeting reaffirmed the project’s core aim: advancing research ethics and integrity by embedding a stronger focus on environmental responsibility. As the world confronts mounting ecological challenges, integrating ethical reflection into research is essential to driving a truly sustainable green transition. The coordination team extends its sincere appreciation to all attendees for their active participation and commitment. With renewed energy, we now move into the next stage of RE4GREEN.
