Earth Summit was the informal name given to the United Nations Conference on Environment and Development (UNCED), and the name with which it is now best known.
Earth Summit, held in Rio de Janeiro from June 3 to June 14, 1992, was unprecedented for a UN conference, in terms of both its size and the scope of its concerns. One hundred and seventy two governments participated with 108 at level of heads of State or Government. Some 2,400 representatives of non-governmental organizations (NGOs) attended, with 17,000 people at the parallel NGO Forum.
The issues addressed included:
- systematic scrutiny of patterns of production — particularly the production of toxic components, such as lead in gasoline, or poisonous waste
- alternative sources of energy to replace the use of fossil fuels which are linked to global climate change
- new reliance on public transportation systems in order to reduce vehicle emissions, congestion in cities and the health problems caused by polluted air and smog
- the growing scarcity of water
The Earth Summit resulted in the following documents:
- Agenda 21
- Rio Declaration on Environment and Development
- Statement of Forest Principles
- United Nations Framework Convention on Climate Change
- United Nations Convention on Biological Diversity
- United Nations Development Programme
- United Nations Environment Programme
- United Nations Industrial Development Organization
- United Nations Conference on Trade and Development
The Earth Summit influenced all subsequent UN conferences, which have examined the relationship between human rights, population, social development, women and human settlements — and the need for environmentally sustainable development. The World Conference on Human Rights, held in Vienna in 1993, for example, underscored the right of people to a healthy environment and the right to development, controversial demands that had met with resistance from some Member States until Rio.
Critics, however, point out that many of the agreements made in Rio have not been realized regarding such fundamental issues as fighting poverty and cleaning up the environment. Moreover, they say business leaders have used the Rio accords to greenwash their corporate image, giving the impression they have improved their behavior when in many cases this has not been the case.
Other criticisms were that the format of the Summit inhibited the discussion of sustainable development by putting development and environment functions in separate compartments, and uniting trade and development concerns, rather than trade and environment concerns, as would be required if tax, tariff and trade policy were actually to be changed to accommodate environmental concerns.
