Almost as much energy is used for refrigeration, air conditioning and insulation worldwide as for transport or heating. On behalf of the Federal Ministry for Economic Cooperation and Development (BMZ), the GIZ ‘Proklima’ project has now been working for some 15 years to help introduce environment- and climate-friendly alternatives to ozonedepleting industrial gases (such as chlorofluorocarbon, CFCs) in partner countries. Proklima thus supports developing and emerging countries in fulfilling their obligations arising from the Montreal Protocol on Substances That Deplete the Ozone Layer. With more than 180 projects and a volume of contracts to date worth almost EUR 50 million, Proklima, on behalf of the German Ministry for Economic Cooperation and Development (BMZ), is the largest bilateral partner under the Montreal Protocol. Since 2008 Proklima has also been working successfully on behalf of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) under its International Climate Initiative (ICI) to disseminate ozone-and climate-friendly technologies. Activities here range from solar-powered fridges for vaccines at health stations in rural areas of southern Africa, to the introduction of climate-friendly room air conditioners in China.
