Commissioned by: German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV)
Partner countries: Costa Rica, Grenada, the Philippines


The objective of the project is to foster sustainable development of the RAC sector by strengthening the competence of key actors and improving related structures. C4 II adapts existing methodologies and develops new tools for replication in other countries, promoting the transformation towards sustainable cooling. Increased ambition triggered by sector specific NDC implementation plans is expected to unlock enormous GHG reduction potential. 

Country specific objective

Cooperation with the three partner countries is twofold: Firstly, the countries will be supported in advancing and implementing the cooling strategies developed with C4 I assistance. Secondly, all three countries will serve as valuable sources of knowledge on cooling strategies, policy approaches and green cooling technology demonstration, which is highly relevant for an increasing number of third countries.  


A sustainable approach enabling a strong multiplier effect lies at the core of the project. Best practices and instruments developed in C4 I are to be made available to other countries for replication in blueprints and guidelines. This includes, for instance, a blueprint on sector-specific NDCs or a roadmap for the introduction of Minimum Energy Performance Standards. Proven approaches are to be systematically transferred to other regions, which in turn will increase awareness of Green Cooling.

Ca­pa­ci­ty buil­ding for trai­ners in the ref­ri­ge­ra­ti­on sec­tor

The ROCA project, in partnership with the national ozone office and the Heat consultancy firm, organized two training sessions for refrigeration and air-conditioning trainers from several towns in Burkina Faso in June.

As part of the promotion of green cooling technologies and the preservation of the ozone layer, two training workshops on air conditioning and refrigeration were organised in Ouagadougou and Bobo-Dioulasso on the theme: "Introduction to the handling of hydrocarbon fluids in Burkina Faso" for refrigeration and air conditioning trainers.

Thirty-five (35) trainers from refrigeration and air conditioning schools and training centres in towns such as Ouagadougou, Ziniaré, Koudougou and Bobo-Dioulasso benefited from this capacity-building. These sessions took place from 29 to 02 June 2023 in Ouagadougou and from 05 June to 09 June 2023 in Bobo-Dioulasso.  This training enabled them to strengthen their teaching practices and their knowledge of the use of natural refrigerants.

As a result, they will now be able to put the skills they have acquired to good use in further training courses on the use of green cooling technologies. Over five days, each group of participants was introduced to the handling of refrigerants and the maintenance of related equipment.

At the end of the course, the participants were satisfied with the quality and relevance of the training. "The content of the modules was rich in information, and the trainer was excellent", said Mr Kambwolé Racine, a teacher at the Lycée Professionnel Régional du Centre.

We learned a lot about natural refrigerants, fluid recovery and the safety involved in handling these fluids. I'm very happy to have taken part in this training course. I would like to thank the GIZ ROCA project for this initiative," added Ms Zongo Mariame, a teacher at the Bassy vocational school in Ziniaré.  This training comes at just the right time in an era when initiatives are being taken to replace the harmful fluids that are swarming the markets with natural, ozone-friendly and climate-friendly fluids. The training was implemented by GIZ Proklima as part of the ROCA (opens in a new window)project, which is co-funded by the European Union and the German Federal Ministry for Economic Cooperation and Development (BMZ).

In future, technicians will be familiar with the maintenance and handling of these refrigerants and appliances containing them. An advantage for the introduction of these appliances in Burkina Faso!
