Those Parties who celebrated Ozone Day this year are to be commended and all Parties are urged to consider celebrating Ozone Day as a way of promoting awareness both of the ozone regime and of the continuing need for vigilance in our efforts to protect the ozone layer.

Lesotho has reported its outstanding data for 2003, including halon consumption of 1.0 ODP tonne, which is in excess of its obligation under the Protocol to freeze halon consumption at its baseline level of 0.2 ODP tonnes, but does represent a reduction in halon consumption compared to 2002, indicating that the Party was working towards compliance with the Protocol's control measures in accordance with paragraph 5 of decision XVI 25.

These discussions complemented information from existing surveys and reports based on project monitoring.

The data is fundamental to our understanding of contemporary processes of global relevance such as ozone depletion, atmospheric pollution, climate change, the melting of ice shelves and glaciers and sea level rise.

All of these ozone depleting substances contain either chlorine or bromine (substances containing only fluorine do not harm the ozone layer).

The anion has the V shape of the ozone molecule.

They are implicated in the formation of ozone holes.

The import was in fact another chemical that is not controlled by the Protocol.

The report of the forty fifth meeting of the Executive Committee to the Multilateral Fund, held in April 2005, recorded the Committee's approval of a methyl bromide agreement with Chile, under which the Party committed itself to reducing total national consumption of methyl bromide to no more than the following levels of consumption in the years listed below

2005 170 ODP tonnes 2006 125 ODP tonnes 2007 84.0 ODP tonnes 2008 65.0 ODP tonnes 2009 50.0 ODP tonnes 2010 43.0 ODP tonnes 2011 36.0 ODP tonnes 2012 31.0 ODP tonnes 2013 zero ODP tonnes.

The agreement further stated that Chile committed to permanently sustaining these annual consumption levels through the use of import restrictions and other policies it may deem necessary .

To request the Ozone Secretariat to

As Chile's methyl bromide baseline is 212.51 ODP tonnes, the above phase out schedule would ensure the Party returned to compliance with the Protocol's methyl bromide control measures in 2005.
