Switzerland reported consumption of 4.730 ODP tonnes of carbon tetrachloride and 348.300 ODP tonnes of methyl chloroform in 2004 for essential uses.

It also represents the first time that the Party has reported any consumption of Annex B, group I, ( other CFCs) Guyana has also reported consumption of 0.085 ODP tonnes of methyl chloroform.

Panama reported consumption of 0.9240 ODP tonnes of methyl bromide in 2004.

The Federated States of Micronesia reported Annex A, group I CFC consumption for 2001 of 1.533 ODP tonnes, compared to a baseline of 1.219 ODP tonnes, indicating a potential deviation from its obligations under the Montreal Protocol.

Kyrgyzstan reported consumption of 2.400 ODP tonnes of halons in 2004.

Turkey reported consumption of 16.440 ODP tonnes of methyl bromide in 2004.

Armenia reported consumption of 1.020 ozone depleting potential ODP tonnes (ODP tonnes) of methyl bromide in 2004.

Guyana reported consumption of 6.300 ODP tonnes of Annex B, group I, (other CFCs) in 2004.

This represents a deviation from the Party's obligation under the Protocol to freeze its consumption of this ODS at its baseline level of 0.0006 ODP tonnes.

Armenia reported consumption of 4.141 ODP tonnes of methyl bromide in 2002 but has reported zero consumption for every other year.

Ozone depletion

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.

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

In addition to the above noted activities, scientific and other research related activities that were reported on included studies on ozone variation, temperature influences on ozone, the interaction between ozone and climate and climactic profiles of ozone.

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.

Adjustments to the Montreal Protocol on Substances that Deplete the Ozone Layer

Support by the NOUs and cooperation by both public and private sources of information has been, in most countries visited, highly satisfactory.

At the time of the country visit this was on the agenda of the Ozone Unit and recently a high level officer was appointed to represent customs in the National Ozone Committee.

Future ozone concentrations are mainly driven by the changes in stratospheric halogen loading, with ozone recovery occurring after the peak of halogen loading.

The workshopMeeting was opened by Mr. Paul Horwitz, Deputy Executive Secretary of the Ozone Secretariat. Speaking on behalf of Mr. Marco Gonzalez, Executive Secretary of the Ozone Secretariat, he noted that theis workshop was being convened in accordance with decision XVI 33 (attached as aAnnex I to the presentis report) which called for the Ozone Secretariat to convene

In addition, the Ozone Secretariat, in cooperation with WMO, organized the Vienna Convention Bureau meeting and the sixth meeting of Ozone Research Managers of the Parties to the Vienna Convention in conjunction with the anniversary ceremony.

In the on going evaluation of methyl bromide projects, smuggling of limited quantities of methyl bromide in small cans was reported for several countries, mostly for the use of small farmers.
