    Climate, environment, management of natural resources


Rising temperatures are driving up global demand for cooling. However, many of the coolants and insulating foams currently in use are harmful to the climate and the environment. In 2023, it is estimated that the refrigeration industry accounted for around ten to twelve per cent of global greenhouse gas emissions.


Natural coolants are used worldwide, which contributes to climate, ozone and environmental protection


All the project’s activities follow the green cooling approach, meaning that environmentally friendly coolants and energy-efficient appliances are used for refrigeration. This minimises effects harmful to the ozone layer and climate.

The global project is aimed at decision-makers and those responsible for cooling and air conditioning in the public and private sectors. It advises them on setting up efficient processes and structures for change, and on developing and mainstreaming innovative technologies.

In addition, the project works with educational institutions to further develop training and further education and to promote the certification and registration of refrigeration technicians for natural coolants.

The programme links national activities with global expert and policy networks. By organising training sessions, webinars or (regional) strategy forums, it promotes knowledge sharing and partnerships for change in the refrigeration sector.

In addition, the project supports the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) in playing a leading role in the transnational discussion on a climate-friendly refrigeration industry and to position Germany as a pioneer and partner. To achieve this, the project provides advice on sustainable cooling and refrigeration technologies as well as on appropriate (safety) standards and guidelines, and certifies corresponding curricula.  Project activities in partner countries, such as certifying the green air conditioning systems of a Thai manufacturer, demonstrate the significant contribution that green cooling technologies make to climate protection and can serve as an international role model.
