St. George’s, Grenada, Monday June 4th, 2018: Two officers of the Grenada Customs and Excise Division participated in the recently concluded Thematic Network Meeting for National Ozone Officers of the

English Speaking Caribbean and Haiti, held in St. Vincent and the Grenadines, from May 28th to June 1st, 2018.

The last two days of the meeting which was attended by customs officers from the region, focused primarily on the roles of customs officers in monitoring and preventing illegal trade in ozone depleting substances (ODS). During those two days, a number of key areas where customs officers are expected to assist National Ozone Units (NOUs) were examined.  Among the key topics discussed were:

  • The Role of Customs Officers – Control measures and reporting obligations under the Montreal Protocol
  • Development of Import/Export Licensing and Quota systems for ODS and HFCs under the Montreal Protocol
  • ASYCUDA and E-Licensing Systems for Border Control of ODS
  • Disaggregation of Customs Harmonised System (HS) Codes for HFCs
  • Practical Exercises on the use of Refrigerant Identifiers

Grenada’s was represented at the meeting by Mr. Rene Parkes, Systems Administrator and Senior Customs Officer with responsibility for training, Mrs. Judy-Ann James.

Mr. Parkes, who is one of the experienced trainers used by the National Ozone Unit to train customs officers, was one of the experts used at the meeting and presented on the following agenda items:

  • Overview of e-Licensing Systems
    • purpose
    • how o establish
    • keyplayer/clienmts
    • illegal trade prevention
  • ASYCUDA and E-Licensing Systems and Border Control for ODS and Refrigerants
    • Grenada’s E-Licensing and Quota Systems

All countries of the Caribbean have already established a licensing system to control trade in ODS, however, Grenada was the first to establish an electronic licensing system imports of ozone depleting substances (refrigerants).


Also attending the meeting from Grenada was, Mr. Curllan Bhola, GIZs technical consultant for the Cool Contributions fighting Climate Change (C4) project  and National Ozone Officer, Mr. Leslie Smith.


St. George’s, Grenada, Thursday May 31st, 2018. On Tuesday May 29th, 2018, Grenada became the 37th country among the 197 Parties to the Montreal to ratify the historic Kigali Amendment to the Montreal Protocol on sunbstances that deplete the ozone layer.

The Ozone Secretariat, based in Nairobi, Kenya, has confirmed receipt of notification from the United Nations Headquarters in New York on the deposition of the instruments of ratification from Grenada.  The Ozone Secretariat has already extended congratulations to the Government of Grenada on this milestone achievement.

In addition to been the 37th Party to ratify the Kigali Amendment, Grenada is the third country in the Caribbean to achieve early ratification, behind Trinidad and Tobago whose was the first and Barbados, the second.

20180524_130113St. George’s, Grenada, Thursday May 24th, 2018: The Government of Grenada is the receipient of thirty (30) mini splits air-conditioning units from the Government of Germany, through the implementing agency GIZ, to be used for a demonstration project to promote the use of natural refrigerants in Grenada.

This initiative is part of the Cool Contributions fighting Climate Change (C4) Project that is executed by the National Ozone Unit in the Energy Division of Ministry of Infrastructure Development, Public Utilities, Energy, Transpot and Implementation. This demonstration project, which is the first of its kind in the Caribbean, seeks also to promote energy efficiency in the cooling sector and to reduce direct and indirect emissions of greenhouse gases (GHG). The project will collect, compare and analyze data between, already installed units using synthetic refrigerants and the new systems using natural refrigerants, R-290. The information gathered from the project would be used to drive a robust public awareness and educational campaign to promote the use of natural refrigerant technology.

The NOU has already engaged entities in the private and public sector to participate in the demonstration project.  The air conditions received (20, 18,000 BTU/h and 10, 12,000 BTU/h) operates with the natural refrigerant R-290 (propane). Natural refrigerants are one of the recommended alternatives to replace the high global warming refrigerants and have the following advantages:

  • Greater energy efficiency
  • very good thermodynamic properties
  • no negative impact on the environment
    • zero ozone depleting potential (ODP)
    • very negligible global warming potential (GWP,2)
  • Requires less refrigerant charge (40%)
  • Quieter operation (less noise)
  • lower operating pressures (extends the life of the compressor)

The AC units were received by the Honorable, Gregory Bowen, Minister under whose portfolio the National Ozone Unit falls.  During the brief hand over ceremony, Minister Bowen expressed the government’s gratitude to the Government of Germany and GIZ and reiterated that the use of these energy efficient AC units can reduce the demand for electricity by 50% and make it more afffordable for ordinary citizens. He further lamented, that energy efficiency and environmental preservation should be a priority in the context of reducing green house gas emissions, especially when the global demand for comfort cooling is expected to triple by the year 2050.

Also attending the ceremony was Permanent Secretary, Patricia Clarke, Head of GIZ, Grenada, Dieter Rottenburer and National Ozone  Offcier, Leslie Smith and the public and private sector participant of the project.




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
