Since the 20th century, international business and international communication have been an integral part of our lives.
Think, for example, of transport companies, banks and other financial institutions, students doing international courses or internships abroad, non-profit organisations providing aid in developing countries and, of course, international government institutions such as the European Union and the United Nations. They all need to make themselves understood in one way or another. Since English has become the hyper-central language, most communication and correspondence is conducted in English.

THE UN CLIMATE TREATY: FROM RIO TO KYOTO
unfccc

In June 1992, the United Nations Conference on Environment and Development (also known as the UNCED) in Rio de Janeiro concluded the Climate Convention. This "United Nations Framework Convention on Climate Change", as it is called in full, is committed to combating climate change, which is caused by the human-induced greenhouse effect.

At this conference in Rio, a total of 154 countries, including the countries of the European Community, signed the Convention, which had been in preparation since December 1990. The Convention officially came into force on 21 March 1994, 90 days after it was ratified (transposed into national law) by the first 50 Parties. The Netherlands ratified the Convention on 17 July 1997..

Question
2) Read the above article. It describes an international treaty. Do you know in which language the different countries probably communicated? How can parties, who cannot manage in English, still participate?
