The island nation takes a major step in combating climate change. By ratifying the Kigali Amendment to the Montreal Protocol on August 10, 2026, Madagascar commits to gradually reducing its consumption and production of hydrofluorocarbons (HFC), with a target reduction of over 80% by 2045. A decision that extends far beyond environmental concerns. Madagascar becomes the last country to join the 172 other Parties that have ratified, accepted or approved the Kigali Amendment. Adopted in 2016, this agreement aims to "reduce the use of HFC, gases widely used in air conditioning and refrigeration." Unlike substances that directly damage the ozone layer, HFC gases are primarily concerning for their very high global warming potential. For Madagascar, the challenge now is to transform international commitment into concrete measures. The gradual reduction of HFC will require changes to refrigeration and air conditioning equipment, cold chain infrastructure, and adaptation of practices by importers and technicians. Ratification opens up a regulatory, technical and financial agenda. The country must strengthen control of refrigerant fluids, support equipment modernization and train professionals in using climate-friendly alternatives. This transition represents a cost for businesses and consumers, but also an opportunity to modernize the refrigeration sector and improve its energy efficiency. Access to international financing mechanisms provided under the Montreal Protocol will be a determining factor. Ratification thus marks less an endpoint than the beginning of a process. The real challenge will now be moving from diplomatic commitment to effective HFC reduction on the ground.
