World Environment Day
June 5, 2026
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.
Background
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.
The Centre for Environment and Development for the Arab Region and Europe (CEDARE) was established in1992 as an international inter-governmental Organization with diplomatic status.
