Air conditioning will certainly continue to be a dynamic market all over the world. We can take economic growth in the air conditioning sector for granted. However, environmental challenges related to energy consumption and the use of refrigerants will increase and involve the International Institute of Refrigeration (IIR) in even more international actions. We need to adapt our industry to sustainable development, and 2011 will be a key year. In 2011, the Mobile Air Conditioning Directive will enter into force in the European Union. Revision of the Fgas Regulation will also take place in 2011. Undoubtedly, these decisions will have important consequences, not only in the European Union but also all over the world. Moreover, the proposals to phase down hydrofluorocarbons (HFCs) within the Montreal Protocol will certainly continue to be considered in United Nations conferences on the ozone layer and climate change in 2011, despite opposition from emerging countries.
