Call for Expressions of Interest to host World Environment Day 2027 or 2028

United Nations Environment Programme (UNEP) is inviting Member States to submit Expressions of Interest to host the global observance of World Environment Day in 2027 or 2028. Observed annually on 5 June and since its launch in 1973, World Environment Day has grown into one of the world’s most influential platforms for environmental outreach. Each year it mobilizes millions of people, thousands of organizations, and governments across the world to take action for a healthier, more sustainable planet. Hosting World Environment Day offers countries a unique opportunity to demonstrate leadership on environmental issues, showcase solutions and capture worldwide attention through high-level participation, global media coverage and UNEP’s advocacy campaign, which reaches millions each year.
