In 1994, the General Assembly proclaimed 16
September the International Day for the Preservation of the Ozone Layer, commemorating the
date of the signing, in 1987, of the Montreal Protocol on Substances That Deplete the
Ozone Layer (resolution 49/114 of 19 December). States were invited to devote the Day to
promote activities in accordance with the objectives of the Protocol and its amendments.
The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of
the rays of the sun, thus, helping preserve life on the planet.
