Initiated by the detection of the so called “ozone hole” over the Antarctic, the Montreal Protocol on Substances that deplete the Ozone Layer came into force in 1987. The Protocol regulates the phase-out of production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFC) in refrigeration and air conditioning. This phase-out has led to the introduction of new, environmental-friendly technologies in industrialized countries. These technologies are now gradually being transferred to developing countries with the help of the Multilateral Fund of the Montreal Protocol. The approach of Proklima has to be regarded in holistic terms: it comprises all sectors which are connected with ozone-depleting gases (e.g. refrigeration plants, air conditioning, agriculture, textile production etc.) and aims at the entire lifecycle of a product (production, utilization, recycling). This is only possible through a close cooperation with the private sector, which relates to almost all steps of the technology cycle, from technology adaptation to market penetration (as you see in the illustration).
