YOUNGO stands for Youth non-governmental organisation.
According to YOUNGO website, YOUNGO is the Youth Constituency of the UNFCCC. It consists of many youth-led organizations, groups, delegations, and individuals working in climate change-related fields.
It runs various Working Groups focusing each on specific aspects of the climate change within the UNFCCC negotiations and events to ensure that perspectives of young and future generations are taken into account in the multilateral decision-making processes. Besides that, YOUNGO members observe and report on climate negotiations, and the implications of their outcomes.
