The year 1972 marked a turning point in the development of international environmental politics: the first major conference on environmental issues, convened under the auspices of the United Nations, was held from June 5-16 in Stockholm (Sweden). Known as the Conference on the Human Environment, or the Stockholm Conference, its goal was to forge a basic common outlook on how to address the challenge of preserving and enhancing the human environment.
Later that year, on 15 December, the General Assembly adopted a resolution (A/RES/2994 (XXVII)) designating June 5 as World Environment Day and urging “Governments and the organizations in the United Nations system to undertake on that day every year world-wide activities reaffirming their concern for the preservation and enhancement of the environment, with a view to deepening environmental awareness and to pursuing the determination expressed at the Conference.” The date coincides with the first day of the landmark Conference.
Also on 15 December, the General Assembly adopted another resolution (A/RES/3000 (XXVII)) that led to the creation of the United Nations Environment Programme (UNEP), the specialized agency on environmental issues.
Since the first celebration in 1974, the World Environment Day has helped UNEP to raise awareness and generate political momentum around growing concerns such as the depletion of the ozone layer, toxic chemicals, desertification and global warming. The Day has developed into a global platform for taking action on urgent environmental issues. Millions of people have taken part over the years, helping drive change in our consumption habits, as well as in national and international environmental policy.
This is the history of World Environment Day.
