The Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer logo was developed to provide a distinct brand for the two treaties across various communication assets and applications. The visual identity guideline is designed to provide a comprehensive overview of applications and correct use of the logo.

Safety standards, Tools

This interactive tool presents a non-exhaustive list of international, regional and national safety standards relevant to Refrigeration, Air-Conditioning and Heat Pump equipment developed by relevant Standards Organizations.

The standards are broadly classified into two categories: Main system safety standards, subdivided into Vertical system safety standards and Horizontal system safety standards, and Supplementary standards.

Categories and examples of laboratory uses (not exhaustive list)

Reference

1. Research and development (e.g. pharmaceutical, pesticide, CFC

and HCFC substitutes)

1.1 Reaction solvent or reaction feedstock (e.g. Diels-Alder and Friedel-Craft Reactions, RuO3 oxidation, allelic side bromination, etc.)

2. Analytical uses and regulated applications (including quality control)

2.1 Reference

– Chemical (ODS monitoring, volatile organic compound (VOC) Detection, Equipment Calibration)

– Toxicant

– Product (adhesive bond strength, breathing filter test)

2.2 Extraction

– Pesticide and heavy metal detection (e.g. in food)

– Oil mist analysis

– Colour and food additive detection

– Oil detection in water and soil

2.3 Diluent

– Zinc, copper, cadmium detection in plants and food

– Microchemical methods to determine molecular weight or oxygen

– Measuring drug purity and residual determination

– Sterilization of lab equipment

2.4 Carrier (Inert)

– Forensic methods (e.g. fingerprinting)1

– Titration (cholesterol in eggs, drug chemical characteristics, “Iodine value”, e.g. in oils and chemical products)

– Analytical equipment (Spectroscopy (Infra-red, Ultra-violet, Nuclear Magnetic Resonance, fluorescence), chromatography (High-pressure liquid chromatography, gas chromatography, thin-layer chromatography)

2.5 Tracer

– Sanitary engineering

2.6 Miscellaneous (including testing)

– Ingredient in material for testing (e.g. asphalt, metal fatigue and fracturing)

– Separation media (separation of extraneous materials such as filth and insect excreta from stored food products)

3. Miscellaneous (including biochemical)

3.1 Laboratory method development

3.2 Sample preparation using solvent

3.3 Heat transfer medium

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Annex IV of the 7th MOP

adopted by decision VII/11

Categories of laboratory and analytical uses allowing the use of methyl bromide

Reference

(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 a laboratory toxicological study

(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

 

 

 

 

Decision XVIII/15

1 Forensic finger-printing is no longer exempted: https://ozone.unep.org/resources/categories-of-laboratory-and-analytical-uses-no-longer-exempted.

Categories of laboratory and analytical uses no longer exempted

Reference

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

Decision VII/11

5. Testing of oil, grease and total petroleum hydrocarbons in water

6. Testing of tar in road-paving materials

7. Forensic finger-printing

Decision XI/15

8. Testing of organic matter in coal

Decision XIX/18

Sustainable Cold Chain and Food Loss Reduction

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.

Gender in treaties

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.
