Passionate changemakers who will inspire and encourage other young people to step up and take-action, GenZero are young leaders providing insights, ideas, youth networks and resources that will help chart the future course of Zero Positive.


The GenZero vision is to create a movement of young people who will fight for climate action and education.

Passionate changemakers, the Zero Positive Youth Advisory Board — GenZero — is run and led by a group of dedicated, inspiring young people who are standing up to take action in their schools and communities, through Zero Positive, on issues of sustainability and climate change.

Events and initiatives organised by the Board include beach clean-ups, tree planting, conferences, video content to inspire other young people, and more. The GenZero team know that there are many young people who want to start making a difference, but don’t have the role models, support or connections to be part of creating positive change, or to start their own projects.


Younger people are, understandably, worried about the future of their planet. Without the power or support they need to get things done, many simply worry about what will happen as the world’s leaders simply add hot air to the debate about carbon emissions.

GenZero is on a mission: to equip young people with the knowledge and support they need to tackle the climate crisis in a positive and actionable way.

They aim to inspire the next generation of climate leaders, empowering exceptional people and building community, as they support the Zero Positive mission of reaching net-zero emissions in our school system through community-level climate solutions.

They also advise Zero Positive and Student Councils on how to better engage young people around climate education and, through GenZero Ambassadors, raise awareness of the Zero Positive for Schools program as they build support for GenZero at associated events.
