World Environment Day (WED) 2010 is aimed to be the biggest, most widely celebrated, global day for positive, environmental action. Through WED, the United Nations Environment Programme (UNEP) is able to give a human face to environmental issues and enable people to realize not only their responsibility, but also their power to become agents for change in support of sustainable and equitable development. UNEP Goodwill Ambassador and top model Gisele Bündchen is the face of the WED 2010 video.

Commemorated on 5 June since 1972, WED is one of the principal vehicles through which the UN stimulates worldwide awareness of the environment and encourages political attention and action.
