The UN is in the forefront of the effort to save our planet: providing and disseminating greater knowledge about climate change and urging crucial political action. The UN Framework Convention on Climate Change (UNFCCC) and the Convention's Kyoto Protocol are major steps in the UN's commitment to set emission reduction targets. The 2009 Climate Change Convention in Copenhagen and MDGs represent UN endeavors to counteract climate change in the near future.
The United Nations has four major headquarters, located in New York, Geneva, Vienna and Nairobi. Its oldest and best-known office, in New York, was constructed in 1950 by a multinational team of leading architects and is now recognized as a modernist landmark. The United Nations headquarters serve not only as administrative offices for the Organization but also as homes for the diverse collection of artwork and historic objects given to the United Nations as a gift by its Member States.
