Categories of laboratory and analytical uses no longer exempted
1. Refrigeration and air-conditioning equipment used in laboratories, including refrigerated laboratory equipment such as ultra-centrifuges
2. Cleaning, reworking, repair, or rebuilding of electronic components or assemblies
3. Preservation of publications and archives
4. Sterilization of materials in a laboratory
5. Testing of oil, grease and total petroleum hydrocarbons in water
6. Testing of tar in road-paving materials
7. Forensic finger-printing
8. Testing of organic matter in coal
Cold-chain systems typically use high-GWP (Global Warming Potential) refrigerants and grid electricity based on fossil-fuels, off-grid diesel-based generation and transport. The urgent challenge is delivering social and economic benefits by expanding cold-chain capacity quickly and affordably, while ensuring minimal pollution and adverse environmental effects.
The organizations of the United Nations system are committed to enabling events at which everyone can participate in an inclusive, respectful and safe environment.
UN system events are guided by the highest ethical and professional standards, and all participants are expected to behave with integrity and respect towards all participants attending or involved with any UN system event.
This document aims to initiate a discussion on gender mainstreaming in the work of the ozone treaties. It begins by providing a brief overview of international instruments on gender and the 2030 Agenda, to which the parties’ implementation of the ozone treaties has over the years made significant contributions. The 2030 Agenda clearly acknowledges the link between environmental protection and gender equality: Sustainable Development Goal 5 (SDG5) is aimed at achieving gender equality and empowering all women and girls, and gender-related aspects are present within several other goals as well.

The Montreal Protocol on Substances that Deplete the Ozone Layer is a global agreement to protect the Earth’s ozone layer by phasing out the chemicals that deplete it. This phase-out plan includes both the production and consumption of ozone-depleting substances. The landmark agreement was signed in 1987 and entered into force in 1989.
When did we realize ozone depletion was an issue, and how did we fix it? By 1985, the globe had already seen advancements in the scientific understanding of ozone depletion and its impacts on human health and the environment. It was then that the Vienna Convention for the Protection of the Ozone Layer was created in response. This agreement is a framework convention that lays out principles agreed upon by many parties. It does not, however, require countries to take control actions to protect the ozone layer. This would come later in the form of the Montreal Protocol.
Pursuant to Decision X/19 (4), the Secretariat is listing below decisions by the Parties on laboratory and analytical uses that should no longer be eligible for production and consumption of controlled ozone-depleting substances under the global exemption:
Of relevance to the global exemption of laboratory and analytical uses are:
Category of laboratory and analytical critical use to allow methyl bromide to be used (Decision XVIII/15(2))
Subject to the conditions applied to the exemption for laboratory and analytical uses contained in annex II to the report of the Sixth Meeting of the Parties, it was decided by the Parties to the Montreal Protocol at their Eighteenth Meeting to adopt a category of laboratory and analytical critical use to allow methyl bromide to be used:
“(a) As a reference or standard:
(i) To calibrate equipment which uses methyl bromide;
(ii) To monitor methyl bromide emission levels;
(iii) To determine methyl bromide residue levels in goods, plants and commodities;
(b) In laboratory toxicological studies;
(c) To compare the efficacy of methyl bromide and its alternatives inside a laboratory;
(d) As a laboratory agent which is destroyed in a chemical reaction in the manner of feedstock;”
