World Environment DayTuesday, June 5, 2018 between 7:00 a.m. - 5:30 p.m.
World Environment Day (WED), commemorated each year on 5 June is one of the principal vehicles through which the United Nations stimulates worldwide awareness of the environment and enhances political attention and action.
WED was established by the United Nations General Assembly in 1972 to mark the opening of the Stockholm Conference on the Human Environment. Since then, it has been held every year, always on the same date, and with an ever growing list of participating countries.
WED is a people's event with global participation. It has previously been celebrated in many ways, with people all over the world getting involved in street rallies, bicycle parades, concerts, school activities and tree planting as well as recycling and clean-up campaigns.
The day is also marked by a global summit attended by important environmental and governmental representatives, each year held by the United Nations Environment Programme (UNEP) at a new host city.
