In part I of this Quick Look, we have gathered a list of a dozen inspiring young sustainability leaders who have both shown their remarkable personalities as leaders, and managed to initiate movements and establish international organizations focused on societal transformations.

Even though in the last two decades youth has been given voice in major international organizations and even government policy making groups, for now, its most potent work seems to be in bridging between local self-organized citizen initiatives and international NGOs. Furthermore, international youth organizations (see SSG QL on Youth Groups) have manifested strong capacity for advocating on sustainability in community organizations, through civic engagement and reforms in education.

This Quick Look is by no means a comprehensive list of all the inspiring youth leaders of today, but only serves as an illustrative proposition aiming to motivate collaboration between varied worldwide youth initiatives.


Here is a list of organizations connected to the leaders profiled above. For more on these and other notable youth organizations, please take a look at the Security and Sustainability Guide Quick Look on Youth Organizations.


  1. Our Future Agenda: A Vision and Plan for Next and Future Generations by Next Generation Fellows(Washington DC, United Nations Foundation, 2021), Sept 2021, 54p.
  1. Fight: How Gen Z is Channeling Their Fear and Passion to Save America by John Della Volpe, St. Martin’s Press, 2021,272p. Deals with the forces shaping Gen Z’s (“the zoomers’ ”) lives, the issues they care most about, and their efforts in standing up to the challenges of the perplexing times they live in. It also confronts statements of older generations about today’s youth being overly sensitive and lethargic.
  1. A Call for Accountability and Action: The Deloitte Global 2021 Millenial and Gen Z Survey, 2021, 39p. The Survey tackled the issues that seem to be of essential importance for millennials and “zoomers”, i.e., environment, social equality and discrimination, and inquired about youth’s satisfaction with business’s role in society. The results suggest that the extreme challenges of the contemporary world, such as pandemic, climate crises and charged sociopolitical atmosphere, make the youth more persistent and vocal in challenging the status quo and recognizing the importance of individual responsibility. The Survey further states that youth express the wish to “work for companies with a purpose beyond profit—companies that share their values” (p.33).
