In 1998, the World Conference of Ministers Responsible for Youth recommended the annual celebration of International Youth Day. The following year it was endorsed by the UN Assembly and the commemorative day has been celebrated each year on 12 August ever since.

In keeping with the UN's 2030 Agenda for Sustainable Development, this year the theme for IYD is The Road to 2030: Eradicating Poverty and Achieving Sustainable Consumption and Production and the leading role young people can play in that.

The UN mission statement for this year reads: "The development and promotion of individual choices and actions that increase the eco-efficiency of consumption of all and minimise waste and pollution is critical to achieving equitable socioeconomic development.

"Yet, many young men and women face barriers to certain green consumption choices. Those barriers to sustainable consumption choices include the high prices of goods and services and a lack of information about the available choices.

"By focusing on the social development dimensions of sustainable consumption and production, this year's theme emphasises a cross-sectoral approach to sustainability and the social, political, economic and environmental inter-linkages needed to achieve it."

In keeping with the day, IBTimes UK lists some inspirational quotes for and about youth
