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 2025.

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).

"As refrigeration technicians, we contribute to environmental pollution and global warming", explains Alimata COULIBALY KINDO, trainer in refrigeration and air conditioning . Her sector is responsible for around 10% of global greenhouse gas emissions. These emissions are caused by the high electricity consumption of the appliances and the high global warming potential of the refrigerants in use. In October 2022, Ms Coulibaly took part in our Cool Training. "In the GIZ Cool Training, I learnt how to use natural refrigerants to reduce pollution and save energy."
One year later, she says that she uses the content of the training in her lessons. She says: "Other generations will come after us. So we are all called upon to protect this planet!"

The project "Climate and Ozone Friendly Cooling in West and Central Africa (ROCA)" has trained more than 150 instructors in its project countries Burkina Faso, Cameroon, Mali and Senegal. In Burkina Faso alone, those trainers have teached over 2 700 students in 2023.

Simplice Tirogo is a nurse and head of the centre for health care and social support in Tovor, Burkina Faso. The project 'Ozone and Climate Friendly Cooling in West and Central Africa (ROCA)' supported his health care centre with a vaccine refrigerator in 2023. "Our refrigerator was broken since 2020, so the vaccines had to be stored in a neighbouring village. Each time, we had to travel 15 km to bring back the vaccines in a transport box that lasted cold during only a day or two. That means, the cold chain was not sufficient and many vaccines spoiled", explains Simplice Tirogo. "Since we received the refrigerator, we can store the vaccines and keep them fresh on site. We can now instantly immunise the pregnant women and the children who come here and whose vaccinations had to be postponed before. This is very satisfying. I thank all partners who made this possible."

During the first year after the acquisition, 11 000 persons profited from vaccinations in Tovor and in nine other newly equipped health care centres. The new refrigerators are even more climate-friendly than the previous ones: they are very energy-efficient and run on the natural refrigerant isobutane (R600a). The necessary electricity comes from solar panels.

Fit for the fu­ture: trai­ning for la­dy coo­ling tech­ni­ci­ans in Se­ne­gal

ROCA conducted two trainings for Senegalese female technicians on climate-friendly cooling and business creation to fight the huge challenges they face when trying to integrate into the labour market.

The project Refroidissement respectueux de l’Ozone et du Climat en Afrique de l’Ouest et Centrale (ROCA) promotes Green Cooling technologies as well as gender equality. ROCA is co-financed by the European Union (EU) and the German Ministry for Economic Cooperation and Development (BMZ). In cooperation with the Senegalese Agence Nationale de la Maison de l’Outil (ANAMO), the project conducted two trainings in February 2023 for 21 technicians of Senegal’s female Refrigeration and Air Conditioning (RAC) Association (RENAFF).

The im­port­an­ce of Green Coo­ling

The women learnt about the latest refrigeration technologies and best practices for their work.

“The training gave us the opportunity to become more skilful as technicians. It was very practical, so we can use it at our places at the local level. Our work will be improved”, said Marème Diop, one of the participants.

The focus lied on energy efficiency and climate-friendly natural refrigerants. As the Director General of ANAMO explained in his discourse during the closing ceremony on 10 March: “The global context of this training is the fight against climate change”.

The sector was responsible for 7% of global emissions in 2021, which is more than three times of the emissions of all air traffic. And the need for cooling is rising. The good news: Emissions can be reduced significantly with energy efficient Green Cooling technologies that use natural refrigerants.

The im­port­an­ce of en­tre­pre­neurship trai­ning

Another important part of the training were lessons on entrepreneurship. In spite of their diplomas and experiences, women graduates in refrigeration and air conditioning are in a very vulnerable situation professionally. The reason for their precariousness is that in the collective consciousness, technical jobs in the industry are men's jobs and therefore companies are very reluctant to recruit women. Therefore, women desperately turn to other jobs that are associated with women. The bravest ones, however, turn to self-employment in order to be able to exercise the business they are passionate about, which is refrigeration and air conditioning.

“The entrepreneurship training helps us to become more autonomous and not to depend on employers”, said Madame Marème Diop. “However”, she continues, “I hope that also more women will get a chance to get hired and to be paid like men”.

Madame Sokhna Fall, the president of RENAFF, also stressed the need for gender equality in her discourse at the closing ceremony. She also expressed her gratitude for the training:

“You have honoured the Femmes Frigoristes from Senegal and we hope that this will be the beginning of a long cooperation!”
