As the first step of a four-year project on youth in earth politics, the paper presents the results of the first systematic inventory of youth actors in the UNFCCC between 1995-2021. This database enables discussion of youth actors’ presence in different negotiation processes over time and their institutionalization as well as socialization in the international political game. The social network of the youth actors on the database will be analyzed with R and Gephi. In addition, the discourses used by the prominent actors identified in the social network analysis will be analyzed through their official statements collected from online searches. Are there ties among youth actors who attend the climate negotiations in formal ways, and what are the ties? Are they linked to informal climate movements? What kind of discourses are shared by youth actors actively involved in formal types of political actions (formal participation) at the transnational level? What are the similarities and differences of the networks of the formal youth climate movement compared to other social movements? By answering those questions, the paper will shed light on the formal political engagement of youth actors at the international level on climate change issues.
