About World Environment Day

World Environment Day was established by the United Nations General Assembly in 1972 at the Stockholm Conference on the Human Environment. Another resolution, adopted by the General Assembly the same day, led to the creation of the United Nations Environment Programme (UNEP).

Commemorated each year on June 5, World Environment Day is one of the principal vehicles through which the United Nations stimulates worldwide awareness of the environment and enhances political attention and action. With thousands of events in UNEP's six global regions, namely, North America, Latin America and the Caribbean, Africa, Asia and the Pacific, West Asia and Europe, World Environment Day is considered one of the largest environmental events of its kind.

Since 1972, 36 World Environment Day celebrations have been held around the globe. World Environment Day 2010 in Pittsburgh will mark the 37th annual celebration. Last year's celebration took place in Omaha, Nebraska. To learn more about Omaha as the 2009 North American Host City, please click here.

World Environment Day is designed to:

On World Environment Day, heads of State, Prime Ministers and Ministers of Environment deliver statements and commit themselves to care for the Earth. Pledges are made which lead to the establishment of permanent governmental structures dealing with environmental management. It also provides an opportunity to sign or ratify international environmental conventions.

But World Environment Day also is a people's event. People around the globe celebrate with colorful activities such as street rallies, city-wide walks, scientific forums, bicycle parades, green concerts, essays and poster competitions in schools, tree plantings, as well as recycling and clean-up campaigns.
