The worldwide network WEEC calls on the United Nations with all their organizations and agencies, governments, the local governments, the parks, museums, environmental education centers, associations, etc. to celebrate every year, on October 14, the World Day of environmental education.
On 14 October, in fact, is the starting day of the Intergovernmental Conference on Environmental Education (14 to 26 October 1977) organized by UNESCO and UNEP in Tbilisi, capital of Georgia.
The initiatives may coincide with October 14, but also take place in the period coinciding with the 1977 conference (until October 26).
The WEEC network also accepts initiatives that for organizational reasons take place in the days preceding or following that date, provided that they correspond to the spirit of celebrating the founding date of environmental education in the world.
