From November 7 to 18, 2016, the city of Marrakesh was host to the meeting of United Nations Framework Convention on Climate Change (UNFCCC), known as the 22nd Session of the Conference of the Parties, or COP 22. Also known as 2016 United Nations Climate Change Conference it also served as the first meeting of the governing body of the Paris Agreement, known by the acronym CMA1. The UNFCCC secretariat (UN Climate Change) was established in 1992 when countries adopted the UNFCCC. In recent years, the secretariat also supports the Marrakech Partnership for Global Climate Action, agreed by governments to signal that successful climate action requires strong support from a wide range of actors, including regions, cities, business, investors and all parts of civil society. Commencing six months ahead of the start of the UN Climate Change Conference in Marrakesh, construction work at the Bab Ighli site was launched. The site was composed of two zones. The “Blue Zone”, placed under the authority of the United Nations, and spanning 154,000 m2 and consisting notably of two plenary rooms, 30 conference and meeting rooms for negotiators and 10 meeting rooms reserved for observers. The second zone, the "Green Zone", was reserved for non-state actors, NGOs, private companies, state institutions and organizations, and local authorities within two areas (“civil society” and “innovations”) each measuring 12,000 m2. The area will also include spaces dedicated to exhibitions and restaurants. The total surface of the Bab Ighli site will be 223,647 m2 (more than 80,000 m2 covered by a roof).
