Friday May 18th, 2018, St. George’s, Grenada:  Two local appliance stores in St. George’s are joining forces with the National Ozone Unit (NOU) and the Cool Contributions fighting Climate Change (C4) Project to promote the use of Natural Refrigerants in refrigeration systems.

The NOU is providing magnetic stickers to to the two appliance stores to be affixed to every refrigerator that is purchased using the natural refrigerants, R-600a.

This initiative is part of the NOU’s trust to replace the high global warming refrigerants, (such as R-134a), that is used in these appliances with alternatives that are environmentally friendly and at the same time more energy efficient.

R-600a (isobutane) is used as a replacement for R-12 and R-134a refrigerants in domestic refrigerators and small commercial refrigerators. This refrigerant has an ozone depleting potential (ODP) of zero and a negligible global warming potential (GWP) of 2.  Additionally, it has very good thermodynamic properties and very good cooling capacity.

Other advantages of this type of refrigerators are:

  • very energy efficient
  • cheaper and requires less refrigerant charge,
  • operate at  lower pressures and extends the life of the compressors
  • operates with less noise (quieter)

The two companies participating in this initiative are Courts grenada Limited (UNICOMER) and L A Purcell.



St. George’s, Grenada: The National Ozone Unit (NOU) in collaboration with GIZ, under the “Cool Contributions fighting Climate Change” (C4) Project, recently launched two (2) publications on Natural Refrigerants.

The publications are aimed at sensitizing the public on the application of natural refrigerants as one of the long term, environmentally friendly, energy efficient alternative technology available for the refrigeration and air conditioning (RAC) sector.

One of the publications provides technical information designed to update the technicians and importers of RAC equipmet and refrigerants, while the other contains general information and is directed to the end users of RAC equipment.

Natural refrigerants have been used for decades but have become increasingly popular in recent times as a longer term, environmentally friendly (ODP=0, GWP=2)*, with energy  efficiency advantages. The NOU together with the C4 Project is promoting the widespread use of natural refrigerants in Grenada. Ultimately the goal is to reduce the use of green house gases (GHGs) and the emissions from the energy input required to operate RAC equipment. This will contribute towards Grenada meeting its Nationally Determined Contributions (NDCs) as well as its other commitments under the Kigali Amendment to the Montreal Protocol.

The publications feature three of the most commonly used natural refrigerants: hydrocarbons, carbon dioxide and ammonia, which are used in a wide range of applications including, domestic refrigerators, unitary/split air condition systems and commercial and industrial refrigeration systems, among others.

The publications are also part of the NOU’s public awareness and educational outreach program to promote the use of low GWP alternatives in the refrigeration and conditioning sector in Grenada.

*(ODP=0, GWP=2) ODP – ozone depleting potential. GWP – global warming potential













St. George’s, Grenada. May 15th, 2018: Stakeholders in the refrigeration and air conditioning (RAC) sector in Grenada met on Tuesday May 15th, 2018, at the conference room of the Grenada Bureau of Standards (GDBS) during a National Public Consultation organized by the National Ozone Unit (NOU) in collaboration with the GDBS to provide comments and to discuss the draft standard for the Safe use, Handling, Storage and Transportation of Refrigerants, including Flammable Refrigerants.

Participants at the consultation represented a wide cross section of the RAC sector, including: the Grenada Refrigeration, Air Conditioning and Ventilating Association (GRAVA), servicing companies, importers, training institutions, Customs, Chamber of Industry and Commerce and end users.

Chairperson of the technical committee for the development of the draft standard and National Ozone Officer, Mr. Leslie Smith, during his introductory remarks lamented on the importance for having the standard in place in light of the introduction of low global warming potential (GWP) alternatives into the country, many of which have concerns with toxicity, flammability and high operating pressures.  He further indicated that this initiative is a clear indication that Grenada is leaving no stone un-turned to convince the manufacturers of these RAC equipment that all the necessary measures are being put  in place to ensure the safe application of these technologies. This situation has been identified as one of the barriers hindering the uptake of such technologies. Additionally, the NOU has been responsible to providing training for over 80% of the RAC technicians in Grenada in natural refrigerant technology.

This national consultation was essentially a second attempt to acquire public comments on the draft standard, since the official period for public comments ended on March 31st, 2018. With the comments provided from the consultation, the final draft will be submitted to the Council of the GDBS for approval.  This will be the second standard to be approved for the RAC sector following the establishment of the standard for the labeling of refrigerant containers that was established in September 2016.

April 12th, 2018, St. George’s, Grenada:  Grenada is among the first countries in the Caribbean region to have installed the low global warming potential (GWP), zero ozone depleting potential (ODP) air condition cooling technology. Twenty-five (25) R-32 mini splits air condition units have been installed at a small hotel in the south of the island.  This is the first known facility to have installed the ozone friendly, low GWP, energy efficient cooling technology in Grenada. R-32 refrigerant has an ODP of zero and a GWP of 675 and is classified by many as a low GWP refrigerant.

Parties to the Montreal Protocol on substances that deplete the ozone layer are encouraged to transition to longer term low or zero GWP alternatives in the phase out of ozone depleting substances (ODS) in the refrigeration an air conditioning (RAC) sector .

This decision poses challenges for low volume consuming countries like Grenada who are essentially technology takers and with very limited options, especially in the mini-split air conditioning sub sector. The current refrigerant technology of choice operates with R-410A as the refrigerant. R-410A has a GWP of 2088 – much too high.

The most practical options available for that sub-sector are natural refrigerants, such as, hydrocarbons  (R-290) with zero  (ODP) and negligible GWP or low GWP options, such as R32. Many developed countries have already set as a policy to transition to R-32 refrigerants in the air-conditioning sector.

The National Ozone Unit (NOU) of Grenada has set as its policy to transition to natural refrigerants as the ozone and climate friendly, energy efficient alternative for the RAC sector.  However, many challenges are experienced in accessing AC units using natural refrigerants.  This novel initiative by the private sector can certainly open the floodgates for others to invest in such environmentally friendly, energy efficient technologies as a mid-term replacement for the high GWP,  hydrofluorocarbon (HFC) refrigerants.


Silver sands

St. George’s Grenada: April 6th, 2018: The National Ozone Officer for Grenada, Mr. Leslie Smith along with GIZ Technical Expert for the Cool Contributions fighting Climate Change (C4), Project, Mr. Curllan Bhola paid a visit to the Grenada Silver Sand Project to discuss refrigeration and air-condition cooling technologies to be installed at the facility under construction. The team met with Chief Engineer Mr. Don Cramer, who outlined the plans for meeting the cooling needs at the facility.

The Silver Sands Project which is due to commence operation in 2018 would be a 5 Star hotel with 44 hotel suites and 9 Luxury Private Villas.

Mr. Smith outlined to Mr. Cramer Grenada’s obligations under the Montreal Protocol and gave a brief over view of the current status in meeting those obligations.  A discussion ensued on the different types of low global warming potential (GWP) options that are available globally and the applicability of them here in Grenada.

This is the first engagement that the NOU has had with a development project of this size.  The NOU, Grenada encourages dialogue and engagement with all project developers to to ensure that environmentally friendly, energy efficient technologies are used in the refrigeration and cooling sector.

At its 79th meeting, the Executive Committee of the Multilateral fund Secretariat for the implementation of the Montreal Protocol randomly selected Grenada as a low volume consuming country of ozone depleting substances to participate in a survey for the evaluation of the refrigeration servicing sector. This evaluation was planned in two stages:  stage one which has already been completed focused on a desk study. Stage two, which is currently ongoing, consists of country evaluation reports following the field visits, which would be based on the findings and recommendations of the desk study.

The field visit for Grenada is scheduled for April 9th – 13th, 2018.  The field visits will focus on key issues stressed in the desk study and will collect updated information about the project implementation, based on direct observation and discussions with various stakeholders.

The objective of the second stage of the evaluation is:

(a) To provide a thorough analysis of the project implementation in the refrigeration servicing sector;

(b) To formulate lessons learned for improving future similar projects; and

(c) To further assess potential issues that could be related to the phasing-down of HFCs in the servicing sector.

Furthermore, the evaluation will strive to provide quantitative data on the impacts and the costs of the activities in the servicing sector to the extent possible.

The evaluation will address the following issues:

  1. a)Project implementation;
  2. b)Policy, legal and regulatory frameworks
  3. c)Technology related issues
  4. d)Demonstration projects for the servicing sector
  5. e)Training and sustainability of training results

Monday March 26th, 2018, St. George’s Grenada: Sixteen (16) Customs and Trade Officers received training in Monitoring, Control and Reporting of Trade in Ozone Depleting Substances (ODS) on Monday March 19th – Tuesday March 20th, 2018.  The training which was organised by the National Ozone Unit (NOU) in conjunction with the Customs and Excise Division of the Ministry of Finance and Energy  is part of the training and initiation exercise for new customs officers.  It is also an integral component of Grenada’s hydrochlorofluorocarbons (HCFC) Phase-out Management Plan (HPMP) to regulate the importation of ODS prevent any attempts of illegal trade in these substances.  Customs officers in Grenada have been receiving this training since the year 2005 and has assisted the NOU tremendously in performing this agency function.

The training was facilitated by Mr. Rene Parkes of the Customs Division and the National Ozone Officer, Mr. Leslie Smith. The officers were exposed to both theoretical and practical sessions. The Customs and Excise division was among beneficiaries in 2017 that received state of the art multi-refrigerant identifiers to assist in the identification of refrigerants in cylinders and refrigeration and air-conditioning.

Among the many topics included in the training were:

  • the Science of the Ozone layer
  • the international response to Ozone Layer depletion
  • Licensing and quota system for ODS
  • ODS HS Classification
  • ODS Smuggling
  • Health and Safety
  • ODS identification

On completion of the training, the officers were presented with Certificates of Participation.  The certificates were presented to them by the Comptroller of Customs, Mr. Donan Victor during a brief closing ceremony.  Addressin the  ceremony, Mr. Victor complemented the trainees  for their co-operation and active participation and implored upon them to put the equipment to full use in performing their roles as agents for the protection of the environment.
