Held annually on June 5, World Environment Day brings together millions of people from across the globe, engaging them in the effort to protect and restore the Earth.

World Environment Day is a global platform for inspiring positive change. People from more than 150 countries participate in this United Nations international day, which celebrates environmental action and the power of governments, businesses and individuals to create a more sustainable world.

The event has been led by the United Nations Environment Programme (UNEP) since its inception in 1973. In 2024, World Environment Day is being hosted by Saudi Arabia, with a focus on land restoration, desertification, and drought resilience.
