This training accompanies the RE4GREEN Starting Guide “Going Beyond Harm: Environmental & Climate Considerations in Research Ethics.” The guide explores how environmental and climate ethics may be relevant even when no significant environmental harm is expected. Learners are invited to read the guidance document first, which introduces three complementary dimensions of ethical reflection: responsible and precautionary research, justice and fairness, and participatory and inclusive research. The exercises in this training support reflection on how research assumptions, methodological choices, societal influence, and participation practices may raise ethical considerations beyond harm assessment alone.
