Ozone Depleting Substances

Ozone Depleting Substances (ODS) phase out in the Cook Islands

This year, we celebrate 35 years of the Vienna Convention and 35 years of global ozone layer protection. World Ozone Day, held annually on September 16, celebrates this achievement.

The 2020 slogan of the day, ‘Ozone for life’, reminds us that not only is ozone crucial for life on Earth, but that we must continue to protect the ozone layer for future generations.

Thanks to the Montreal Protocol, the ozone layer is healing and expected to return to pre 1980 values by mid-century. In support of the Protocol, the Kigali Amendment, which came into force in 2019, will work towards reducing hydrofluorocarbon (HFCs), greenhouse gases with powerful climate warming potential and damaging to the environment.

An update on the Ozone Project

The Cook Islands is pleased to announce that we now join ten (10) other Pacific Island national and eighty one (81) countries in ratifying the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer.

The agreement was formally announced on the 22nd August 2019 by the United National Secretary General Anto0nio Gutteres.
The news of the ratification is received in a timely manner, as the National Environment Service commemorated International Ozone Day which is commemorated annually on the 16th September.

The Kigali Agreement was formally reached at the Parties of the Montreal Protocol on Substances that Deplete the Ozone Layer, in which the National Environment Service actively participated in during the 28th Meeting of the Parties in 2016 in Kigali, Rwanda to phase-down the use of hydrofluorocarbons (HFC).

The phase-down of HFCs under the Montreal Protocol has been under negotiation by the Parties since 2009 and the successful agreement on the Kigali Amendment continues the historic legacy of the Montreal Protocol. The Kigali Amendment entered into force on the 1st January 2019 provided that it is ratified by at least 20 Parties of the Montreal Protocol.

HFCs are commonly used alternatives to Ozone Depleting Substances (ODS). While not ozone ODS’s gases themselves, HFCs are greenhouse gases which can have high or very high global warming potentials (GWP) that affects Climate Change. The use of HFCs has facilitated the rapid phase-out of ODS including CFC, HCFC and has helped protect the Earth’s fragile Ozone Layer. However, the High GWP of HFCs is a major disadvantage and every effort now needs to be made to use non-ozone depleting alternatives with a low climate impact. In addition to this, the National Ozone Unit is working on updating the regulation to include the provision of a Technicians Licence for service technicians to have in order to service equipment containing ozone depleting substances legally.  This measure includes the requirement for technicians to attend ‘Good Practices in Refrigeration’ training and refreshers.  This training covers the proper handling of the ozone depleting substances and education on the effects of the substances so that technicians will become more mindful that they need to avoid as much as possible, any gas leakages or discharges into the atmosphere.

The other new provisions is to create a quota system for amounts of ozone depleting substances imported by each company. This quota is set to decrease over time to eventual phase out.  Premises or companies that store and/or sell ozone depleting substances will also have to be permitted to do so and will need to fill particular criteria to obtain a permit to sell or store ozone depleting substances.  The requirement for licences or permits to sell  and store ozone depleting substances will also be added to the regulation.

All these additions need to become implemented into the Cook Islands law to fulfil our obligations to the Vienna Convention and the Montreal Protocol.  As the Cook Islands are a Party to these treaties, so shall the Cook Island follow the protocols put in place to reduce and phase out ozone depleting substances.


In 2019 and 2020, the National Ozone Unit (NOU) held a technician training and a refrigerant recovery program in Aitutaki. The team consisted of two qualified RAC technicians and the recovery training program was conducted at the Aitutaki Waste Management site and the Pacific Resort Aitutaki.
7.55kg of gas was recovered from eight (8) aircon units that was stored at the waste facility site and less than 1kg from units at the Pacific Resort Aitutaki. During the teams stay, the NOU conductged presentations at the schools on Ozone Depleting Substances.

Importers Permits

ODS Import Permit for the importation of bulk ODS – existing ODS Equipment Import Permit for the importation of appliances that contain ODS – may be introduced to monitor all amounts of gases coming in and track ODS based equipment

Technicians Licenses
Technicians Licence for the handling and use of ODS Technicians training ‘Good Practices in Refrigeration’

Option 1: Montreal Protocol, reductions in HCFC’s
– 2015: 10% reduction
– 2020: 35% reduction
– 2025: 67.5% reduction
– Over next 10 years: 97.5% reduction

Option 2:  The preferred option of the National Ozone Unit
– 2013: ban of HCFC equipment imports and 15%

reduction of HCFC for servicing existing equipment
The idea here is that if HCFC based equipment is banned there won’t be an increase of HCFC imports, it will just be the  servicing of existing units that will come to the end of their life most likely by 2020.  In addition to this, a survey of  household refrigerators showed that already 94.1% of those households surveyed are already non HCFC based.


Ongoing customs training is in order to train Customs officers to identify and monitor ozone depleting substances and also methods of smuggling.  There is some concern with the upcoming HCFC Phase out, that smuggling will start to occur.

Why Ozone Depleting Substances are bad

The ozone layer is situated in the stratosphere about 10-50km above the Earth and has the important role in protecting the Earth from the sun’s harmful ultraviolet radiation (UV-B). Increased exposure to UV-B radiation intensifies the chance of developing certain types of cancers, especially skin cancer. UV-B radiation also affects marine and terrestrial ecosystems, altering food chains, growth and biochemical cycles. This radiation damages the aquatic life (plankton) residing just below the surface of salt and fresh water, which form the foundation of the Earth’s food chain.

Ozone Depleting Substances in the Cook Islands

It is estimated that since the 1980s, four types of ozone depleting substances have been imported into the Cook Islands in bulk form. These are: chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), methyl bromide, and halons. CFCs and HCFCs are used for refrigeration and air-conditioning, methyl bromide was used for quarantine fumigation, and halons are used for fire protection. Present consumption of most ozone depleting substances in the Cook Islands is exclusively in the refrigeration and air conditioning sector.

Montreal Protocol and the Vienna Convention

The Montreal Protocol is an implementation mechanism under the international agreement the Vienna Convention that is designed to eliminate the production and consumption of harmful ozone depleting substances. Some examples of these substances include chemicals such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride and methyl bromide which have many applications including refrigeration, air conditioning, cleaning electronic components, solvents, fire extinguishers, and quarantine and pre-shipment cargo.

Cook Islands and the Montreal Protocol

The Cook Islands became party to the Montreal Protocol on the 22nd December 2003. Prior to this, work done in the country with regards to implementation of the Montreal Protocol were a one-day workshop for government departments and small industrial enterprises conducted by SPREP in 1999. A five-day assessment on the current consumption of ozone depleting substances was conducted by SPREP and the National Environment Service between August and September 2004. The findings of this assessment were used to develop a National Compliance Action Plan (NCAP) for the Cook Islands, which was completed in October 2004. The lead agency responsible for implementing and managing the NCAP programme will be the National Compliance Centre (NCC) in the National Environment Service. However, given the complexity and cross-sector nature of the plan, it will be necessary for the NCC to collaborate with a number of other agencies and organisations, the principal ones being:


Customs Department

The Customs Department will enforce proposed regulations controlling the importation of ozone depleting substances. Data recorded of all imports detailing the type and amount of ozone depleting substances entering the country would be stored at the Customs department under their current arrangements with the Statistics Department and collated by the NCC office for data reporting needs.


Refrigeration technicians

Refrigeration technicians will be involved in the training and certification courses for trainers and future technicians will need to be licensed to handle, capture, and recycle ozone depleting substances.

The NCC will also work closely with personnel in the National Environment Service dealing with climate change and waste related conventions (Stockholm, Persistent Organic Pollutants, Rotterdam, Basel, Waigani etc) towards a harmonised approach to controlling consumption of and trade in environmentally harmful substances.

Regional Strategy to Implement the Montreal Protocol (on Substances that deplete the Ozone Layer) in the Pacific

The Cook Islands Ozone Depleting Substances Project is the result of an approved “Regional Strategy to Implement the Montreal Protocol (on Substances that Deplete the Ozone Layer) in the Pacific”. The Cook Islands are one of three additional countries (alongside Niue and Nauru) to join the Regional Strategy in 2006. The Regional Strategy is co-coordinated by the Secretariat of the Pacific Regional Environment Programme (SPREP).

Goal: To completely phase-out the use of the most commonly used and harmful ozone depleting substances, CFCs, by the year 2006.

1) To strengthen institutions by establishing National Compliance Centres in all core and additional countries of the Regional Strategy;

2) To establish national controls (regulations, licensing and monitoring systems) on the import of ozone depleting substances;

3) To build capacity through training programmes on “good practices in refrigeration” (for refrigeration technicians) and on “control of ozone depleting substances imports” (for customs officers).

Action Plan and Projects under the NCAP

In order to ensure the Cook Islands’ compliance with the Montreal Protocol the following Action Plan has been developed.

1. Maintain compliance with the Montreal Protocol while preparing an economically viable accelerated phase-out program.
2. Establish a National Compliance Centre (NCC) office to co-ordinate, implement, and monitor the phase-out program.
3. Prohibit any new activity related to the import, production or use of ODSs in new equipment.
4. Ban of import of ozone depleting substance-using and ozone depleting substances-containing equipment (including new and second-hand domestic refrigerators using CFC-12 as the refrigerant).
5. Introduction of controls on the import (and export) of all ODSs (including licensing, taxation and/or quotas as appropriate).
6. Strengthening ozone depleting substances import/export monitoring program by developing a licensing system.
7. Consideration of a system of fiscal incentives/disincentives in favour of non-ozone depleting substances alternatives and transitional substances.
8. Implement and monitor training of customs officers to ensure proper control of import and export of ozone depleting substances and information collection and submission.
9. Implement and monitor training of refrigeration service technicians on good practices in refrigeration to minimise the use of ozone depleting substances and mitigate their emissions into the air during the service of refrigerators.
10. Conduct public awareness campaign on necessity and means for protection of the Ozone Layer of the Earth and the government’s commitment to phase out ozone depleting substances.

Education, training, legislation, regulations and other incentives will ensure that the Cook Islands will continue to meet its obligations under the Montreal Protocol.
