Marked annually on 12 August, International Youth Day is an opportunity to celebrate the 1.2 billion young people who are emerging into adulthood and finding their voices in a fast-changing world. Although there’s no universal definition of youth, the UN defines it as “those persons aged between the ages of 15 and 24 years”, which amounts to around 16% of the world’s population.

This year’s theme is ‘green skills for youth: towards a sustainable world’. A successful transition towards a greener world will depend on the development of green skills in the population. Green skills are “knowledge, abilities, values and attitudes needed to live in, develop and support a sustainable and resource-efficient society”.
