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.
