Carbon tetrachloride

On the basis of that review, TEAP could, if appropriate, revise the funding requirements estimated for CTC.

Other representatives stressed the need to consider additional reduction steps for methyl bromide, as well as the variable reporting of carbon tetrachloride data.

Considering that the drastic control measure for carbon tetrachloride that has been referred to puts at risk the analytical and laboratory uses required in Parties operating under Article 5,

The reporting of CTC had been variable and would be addressed to the extent possible and he agreed that the issue of HCFCs could be re examined at such time as the Executive Committee took a decision on that matter.

To monitor closely the progress of Switzerland with regard to the phase out of Annex B, group II, substances (carbon tetrachloride) and Annex B, group III, substances (methyl chloroform).

E. Decision XVII __ Laboratory and analytical uses of carbon tetrachloride

The representative of TEAP clarified that despite requests, no detailed information had been received by TEAP from the Democratic People's Republic of Korea or Romania for carbon tetrachloride.

E. Draft decision XVII E Laboratory and analytical uses of carbon tetrachloride

Bearing in mind that the Parties operating under paragraph 1 of Article 5 must reduce by 2005 consumption of carbon tetrachloride by 85 per cent with respect to their base line,

E. Decision XVII Potential non compliance in 2004 with consumption of the controlled substance in Annex B, group II (carbon tetrachloride), and Annex B, group III (methyl chloroform), by Switzerland, and request for a plan of action

The Committee observed that, at its first meeting, it had considered notifications concerning regulatory actions on methyl bromide and on carbon tetrachloride, some of which were based on decisions or assessments under the Montreal Protocol on Substances that Deplete the Ozone Layer.

Taking into account that carbon tetrachloride has an important use in laboratory and analytical processes, which are also fundamental for many applications in the Parties operating under Article 5, and that alternatives are not yet available to allow application of international standards,

As for carbon tetrachloride emissions and reduction opportunities, he noted that while there had been data uncertainties, 2002 production of CTC was less than 200,000 metric tonnes, with almost half coming from developing countries.

Finally, the Committee noted that the European Community had submitted a request for an emergency exemption to the Ozone Secretariat to authorize the use of the eight litres of CTC required for the manufacture of radiolabelled cyanocobalamin, and that such use was recommended by the Panel and the Committee co chairs.

Titanium metal was not used outside the laboratory until 1932 when William Justin Kroll proved that it could be produced by reducing titanium tetrachloride (TiCl4) with calcium.

The current year, 2005, will see Parties undertake commitments to further controls on CFCs, halons, carbon tetrachloride, methyl chloroform and methyl bromide.

Electricity generation is the fourth highest combined source of NOx, carbon monoxide, and particulate matter in the US.

The study noted that three Parties operating under Article 5 accounted for 97 per cent of the total consumption in that area, and that each of those Parties had national carbon tetrachloride phase out plans either already in place or in prospect for new uses.

The Committee also recommended that table B of decision XV 7 be updated to reflect any changes made to table A and that Israel be included in table B because its use of carbon tetrachloride (CTC) for removing nitrogen trichloride (NCL3) in the production of chlorine was a well known process agent use.

In previous years, Switzerland has reported consumption of carbon tetrachloride and methyl chloroform for laboratory and analytical uses consistent with the Protocol's global laboratory and analytical use exemption.

One representative expressed his concern that the table supplied by TEAP did not contain data on emissions for most of the proposed uses of carbon tetrachloride, or on consumption for the proposed use of CFC 113.

To allow from 2006 Parties operating under Article 5 to apply the criteria and procedures of global exemption for carbon tetrachloride in laboratory and analytical uses that are currently established for Parties not operating under paragraph 1 of Article 5.
