The World Environment Day slogan selected for 2007 is Melting Ice – a Hot Topic? In support of International Polar Year, the WED theme selected for 2007 focuses on the effects that climate change is having on polar ecosystems and communities, and the ensuing consequences around the world.

The main international celebrations of the World Environment Day 2007 will be held in Norway. UNEP is honoured that the City of Tromsø will be hosting this United Nations day (read the press release). Please visit the Norwegian Polar Institute WED website for more information on the celebrations in Norway [English] - [Norsk].

The day's agenda 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. World Environment Day is a people's event with colourful activities such as street rallies, bicycle parades, green concerts, essays and poster competitions in schools, tree planting, as well as recycling and clean-up campaigns.

When did it all begin?

World Environment Day was established by the United Nations General Assembly in 1972 to mark the opening of the Stockholm Conference on the Human Environment. Another resolution, adopted by the General Assembly the same day, led to the creation of UNEP.

How can you celebrate World Environment Day?

World Environment Day can be celebrated in many ways, including street rallies, bicycles parades, green concerts, essay and poster competitions in schools, tree planting, recycling efforts, clean-up campaigns and much more. In many countries, this annual event is used to enhance political attention and action.

Heads of State, Prime Ministers and Ministers of Environment deliver statements and commit themselves to care for the Earth. More serious pledges are made which lead to the establishment of permanent governmental structures dealing with environmental management and economic planning. This observance also provides an opportunity to sign or ratify international environmental conventions.

On this World Environment Day, let us examine the state of our environment. Let us consider carefully the actions which each of us must take, and then address ourselves to our common task of preserving all life on earth in a mood of sober resolution and quiet confidence.
