September saw the commemoration of several international days to raise environmental awareness, from the International Day of Clean Air for Blue Skies that fell on the 7th, International Day for the Preservation of the Ozone Layer on 16th, and World Maritime Day on the 24th.
Encouraged by the increasing interest of the international community in clean air, and emphasizing the need to make further efforts to improve air quality, including reducing air pollution, to protect human health, the General Assembly of the United Nations decided to designate 7 September as the International Day of Clean Air for blue skies.
