World Environment Day (WED) was established by the UN General Assembly in 1972 to mark the opening of the Stockholm Conference on the Human Environment. Commemorated on 5 June each year, WED is one of the principal vehicles through which the United Nations stimulates worldwide awareness of the environment and enhances political attention and action.
The agenda for WED is to give a human face to environmental issues; empower people to become active agents of sustainable and equitable development; promote an understanding that communities are pivotal to changing attitudes towards environmental issues; and advocate partnership which will ensure all nations and peoples enjoy a safer and more prosperous future.
WED, established under the premise of the United Nations Environment Programme (UNEP), whose headquarters are in Nairobi, Kenya, and is celebrated in more than 100 countries around the world. As a day that stimulates awareness of the environment and enhances political attention and public action, the first World Environment Day was celebrated in 1973. The Day is hosted every year by a different city with a different theme and is commemorated with an international exposition on the week that 5 June is on.
The theme for WED 2009 was 'Your Planet Needs You-Unite to Combat Climate Change'. It reflected the urgency for nations to agree on a new deal to combat climate change, and the links with overcoming poverty and improved management of forests. The hosting of WED 2009 by Mexico reflected the growing role of the Latin American country in the fight against climate change, including its growing participation in the carbon markets.
