Interested in Green Cooling? GIZ Proklima's Cool Training offers many options. Learn more about the safe use and handling of natural refrigerants. Discover ways to implement policies in your country, and promote sustainable, environmentally friendly cooling. Cool Training offers all this and more. Let’s fight global warming.
GIZ Proklima's Cool Training offers a series of international trainings focused on the safe use of natural refrigerants in the RAC sector. Launched in 2014, the programme supports the worldwide adoption of sustainable cooling technologies by offering training on the safe handling of natural refrigerants. The main target groups are international RAC technicians and trainers, as well as political decision makers from developing countries and emerging economies. Depending on the training programme, courses are offered as one-week or two-week packages for policy-makers and technicians.
Cool Training Online Courses
Since 2022, we offer e-learning courses that provide the basic theoretical knowledge needed to participate in the face-to-face trainings. The latter will take place in Germany and will focus on practical exercises. The e-learning is also open for all other interested persons.
The online course uses the e-learning platform www.atingi.org. It consists of 19 videos (3-8 minutes) for self-learning, and additional download material.
Participation is open to everybody and free of charge.
The course is available in English, French, Spanish and Portuguese.
Interested? Please follow these steps:
- Register at www.atingi.org
- Search "Cool Training" in the search button on the atingi platform
- Choose your preferred language option
- Get started!
The online course is complemented by a forum where you can post questions about the content of the course.
In case of problems write an email to write an e-mail to cool.training[at]giz[dot]de.
In-person Cool Trainings in 2026
Depending on the training programme, in-person courses are offered as one-week sessions for policy-makers or two-week sessions for technicians. The courses generally take place in Maintal, Germany.
The schedule for face-to-face training in 2026 is still to be confirmed. Dates will be announced here as soon as they are available.
If you are interested in participating, please contact us via cool.training[at]giz[dot]de.
Content of the training
Content of the training
The overall objective of the Cool Training initiative is to spread in-depth knowledge and the capacity to operate and maintain cooling technologies based on natural refrigerants. Participants can learn about the use of propane (R290) and CO2 (R744), as well as ammonia (R717). The training includes at least one visit to innovative German companies, such as natural refrigerant producers, RAC component manufacturers and refrigeration plants. It heavily emphasises hands-on practical sessions (70% practice, 30% theory), creating expertise that can be applied immediately in the participant's line of work.
For technicians:
Practical and theoretical content includes: safety and environmental requirements according to DIN EN 378-1:2017-03 to 4:2017- 03; the application of propane (R290) and CO2 (R744) as refrigerants; the recovery of R134a and its replacement with R290 in RAC appliances; refrigerant circuit pipe joining and installation methods; leak finding and tightness test activities in practice.
For policy-makers:
Furthermore, a one-week Cool Training course has been developed for policymakers and stakeholders working on the topic of natural refrigerants and the protection of the ozone layer and climate. Participants receive a certificate of completion after finishing the training and passing the written examination. Proklima encourages alumni to act as knowledge multipliers in their home countries and regions.
The training is conducted in cooperation with the Bundesfachschule Kälte-Klima-Technik (BFS), one of the leading German vocational training centres for refrigeration technology with more than fifty years of experience.

Benefits and fees
Benefits
The demand for natural refrigerants is rising rapidly. The growth is driven by recent national, regional and international politico-legal developments, such as the EU F-gas regulation and the Kigali Amendment. The training courses help RAC experts and trainers gain a competitive edge over their peers by staying up to date and working in accordance with current regulations and standards, while at the same time moving away from unsustainable technologies and refrigerants, such as HFOs and HFCs (e.g. R134a). Alumni can use their expertise to help environmentally-conscious consumers and industries to meet their Green Cooling objectives, while helping the national government meet its Nationally Determined Contributions – the national climate change mitigation commitments under the Paris Agreement.

Expertise and organisation
GIZ Proklima is a programme of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH. It has been providing technical assistance to developing countries since 1996. Under commission of the Federal Ministry for Economic Cooperation and Development (BMZ), GIZ helps in the implementation of the provisions of the Montreal Protocol on substances that deplete the ozone layer. Proklima launched the Cool Training series in 2014. Since then, more than 450 trainers, lecturers, and representatives of National Ozone Units (NOU) and implementing agencies have been officially cool-trained. The training is implemented in cooperation with Bundesfachschule Kälte-Klima-Technik (BFS), one of Germany’s leading vocational training centres for cooling technology with more than fifty years of experience.
