11.6Conclusions


Halons, more than some of the other ODSs, are readily accessible for collection, storage, and disposal or reuse. Owing to the continued global demand in applications such as aviation, the HTOC has recommended that destruction as a final disposition option should be considered only if the halons are cross-contaminated and cannot be reclaimed to an acceptable purity. Approved ODS destruction technologies and facilities can be found in many countries, and some already have experience destroying some types of ODS including, to a very limited extent, halons. The recent introduction of carbon credits for ODS destruction creates a limited window of opportunity to increase ODS recovery at equipment end of life and to avoid potential emissions altogether by destroying unwanted material. Halon destruction is currently eligible for credits under one voluntary standard, however there are other serious considerations with regard to halon destruction in general. The Parties may wish to consider asking TEAP/HTOC to investigate the issues related to halon destruction further in order to better understand the full implications to the halon phase out under the Protocol, and the impacts to ozone layer recovery and climate protection.
