Youth are increasingly recognized for their important role in shaping environmental decisions surrounding conservation. Regrettably, youth who are crucial decision-makers are often excluded from environmental governance spaces due to structural barriers, both economic and political. As highlighted by recent environmental justice literature, this marginalization hinders their active participation in the decision-making process. The recent publication of the International Union for Conservation of Nature (IUCN) Youth Strategy 2022–2030 has brought prominent environmental organizations into the debate. The IUCN World Conservation Congress (WCC) presents a useful example from which to understand how youth access and participate in decision-making at the highest level of governance in a prominent global conservation organization. We used event ethnography and participant observation methods to study the WCC Forum in Marseille, France (2021). We sought to examine the geopolitical intricacies of power and the underlying inequalities at the root of youth engagement, or lack thereof. We considered the IUCN's engagement with youth, outlining the process from previous resolutions and recommendations to the publication of the IUCN Youth Strategy in 2022. The results from the youth narratives we compiled showed that youth are not a monolith, that tokenism should be challenged, and that youth have agency but require support. We argue that when youth are mobilized in metalevel decision-making spaces, their engagement is stratified and unequal. We situated youth engagement in decision-making through the perspective of environmental organizations as a contribution to environmental governance and youth literature.
