This report presents the findings of a critical review of the greening approach undertaken by the NGO People in Need (PIN), carried out by Groupe URD between June 2025 and December 2025. Initially conceived as methodological or strategic support, the assignment evolved into an in-depth analysis of a process already well under way, revealing a structured, ambitious, and notably pragmatic ecological transition. PIN’s experience undoubtedly provides inspiration, but this report does not present it as a normative model. Rather, it offers one interpretation, among many possible, of a greening dynamic in progress, a journey that, like any change, is built step by step.
