Ozone and Cli­ma­te Fri­end­ly Coo­ling in West and Cen­tral Af­ri­ca (RO­CA)

The ROCA project promotes ozone- and climate-friendly cooling technologies in the four African countries Burkina Faso, Cameroon, Mali and Senegal. It started in April 2021 and will run until March 2024.

RAC appliances are spreading rapidly across Africa, particularly in the cities. In rural areas, on the other hand, there is still a lack of refrigeration equipment for agriculture and medical care. The rising number of RAC will contribute to increased energy needs as well as the use of refrigerant gases, many of which are highly damaging to the ozone layer and the global climate. To limit this dual impact, it is necessary to introduce a wide range of ozone- and climate-friendly cooling solutions.

ROCA (Refroidissement respectueux de l'Ozone et du Climat en Afrique de l'Ouest et Centrale) contributes to an increasing use of Green Cooling technologies through improving the policy and regulatory framework on the one hand and building capacity for the use of such technologies on the other.

ROCA includes the following measures: 

  • Analysing current and future cooling demands in the partner countries (RAC inventories)
  • Advisory services for the governments, based on RAC inventories and assessment of existing policies
  • Trainings of RAC technicians on safe handling of natural refrigerants online and in Germany (Cool Trainings) as well as in the partner countries
  • regional workshops on climate finance and business models to promote the accelerated adoption of ozone- and climate-friendly as well as energy-efficient appliances using natural refrigerants
  • Pilot projects using Green Cooling technologies; e.g.
    • Air Conditioning: R290-ACs for public buildings
    • Food Security:
      • cold rooms for agricultural cooperatives in Mali and Senegal;
      • an ice machine for a fishermen's cooperative in Senegal
      • a cold chain between the slaughterhouse and the market in Ouagadougou, Burkina Faso
    • Good Health: cooling for vaccines in Burkina Faso and for a hospital in Cameroon

The project is co-funded by the European Union and the German Federal Ministry for Economic Cooperation and Development (BMZ).

Green Coo­ling equip­ment for Bur­ki­na Fa­so

20.04.2023 , News :

The Ministry of the Environment, through the project Re­f­ro­idis­se­ment re­spec­tueux de l'Ozone et du Cli­mat en Afri­que de l'Ou­est et Cen­tra­le (ROCA), officially handed over a batch of medical and educational equipment to the Ministries of Health and Education, on Thursday 30 March 2023 in Ouagadougou. This handover is part of the promotion of the use of energy-efficient and ozone-friendly cooling technologies.

The preservation of the ozone layer is important for the survival of all living beings. It is therefore essential to reduce the climate impact of the refrigeration sector in Burkina Faso. And this requires the increased use and mastery of Green Cooling and air conditioning technologies.

The Secretary General of the Ministry of the Environment, Dr Bouraima Kouanda, handed over sanitary and didactic material to the Ministry of Health and the Ministry of the Environment, on Thursday 30 March 2023 in the premises of the National Ozone Office in Ouagadougou. The ceremony of reception of this equipment took place in the presence of the European Union, the ROCA (opens in a new window)project coordinator, the general secretaries of the beneficiary ministries and several guests.

This batch of equipment, worth about 85 million CFA francs, is composed of 10 natural fluid refrigerators, ten (10) solar panels, four (4) teaching benches, five (5) autogenous welding kits, eight (8) maxigas cartridges and eight (8) oxygen cartridges.

This equipment acquisition was made possible by the GIZ's Ozone and Climate Friendly Cooling in West and Central Africa (ROCA) project, funded by the European Union and the German Federal Ministry for Economic Cooperation and Development.

This grant also falls within the framework of strengthening the operational and technical capacities of the beneficiaries. According to Dr Silem Sassi, team leader for human and social development and representative of the European Union, "the refrigerators will enable the populations of the East and South-West communes to have equitable access to high-quality vaccines in the health and social promotion centres (CSPS). As for the teaching benches, they will strengthen the technical skills of learners in the Ouagadougou and Bobo-Dioulasso training centres in the safe handling of propane-R290, used in air conditioning and refrigeration.

The beneficiaries, through their representative, Dr Estelle Dabiré, Secretary General of the Ministry of Health, expressed their thanks to the donors.

Together we can protect the ozone layer.
