World Environment Day

World Environment Day is held each year on June 5. It is one of the principal vehicles through which the United Nations (UN) stimulates worldwide awareness of the environment and enhances political attention and action.


It’s time to raise our voices to tell the world that we need action now.
This World Environment Day, it’s Time for Nature.

World Environment Day was established by the United Nations General Assembly in 1972 to mark the opening of the Stockholm Conference on the Human Environment. Another resolution, adopted by the General Assembly the same day, led to the creation of UNEP. It is hosted every year by a different city and commemorated with an international exposition through the week of June 5.

When was first Environment Day celebrated?

World Environment Day was established by the UN General Assembly in 1972 on the first day of the Stockholm Conference on the Human Environment, resulting from discussions on the integration of human interactions and the environment. Two years later, in 1974 the first WED was held with the theme “Only One Earth”.

How we Celebrate

World Environment Day is celebrated in many ways in countries such as Kenya, New Zealand, Poland, Spain and the United States. Activities include street rallies and parades, as well as concerts, tree planting, and clean-up campaigns. In many countries, this annual event is used to enhance political attention and action towards improving the environment. This observance also provides an opportunity to sign or ratify international environmental conventions.
