Ozone Depleting Substances

India is a signatory of Montreal Protocol and being a developing country, its industries are eligible for technical and financial assistance through multilateral fund. The enterprises which qualify the prescribed norms of Ozone Depleting Substances consumption and have been in existence prior to the 25th July 1995 are eligible for funding for conversion to Non-ODS technologies from Montreal Protocol Multilateral Fund. The Ministry of Environment & Forest, Govt. of India is a nodal Ministry for implementation of provisions of Montreal Protocol in India.

Government of India has already initiated number of policy measures both legislative and fiscal to encourage early adoption of Non-ODS technologies. The All India Survey conducted by NSIC in 1994 indicated that a total 9110 ODS consuming units are in existence consuming 3006.0MT of Ozone Depleting Substances. The major sectors are Refrigeration & Air Conditioning, Solvents, Foams, Aerosols, and Fire Extinguishers. In Andhra Pradesh a total of 450 Ozone Depleting Substances consuming units have been identified out of which a majority are in Refrigeration and Air Conditioning sector.

In order to regulate production and consumption of ODS, Government of India has notified "Ozone Depleting Substances" (Regulation & Control Rules) 2000 vide Gazette Notification No: 471 dated 19th July, 2000 under the Environment Protection Act, 1986. Small Industries Service Institute., Hyderabad registers the units involved in production, conversion and handling of Ozone depleting Substances in the state of Andhra Pradesh.

Units involved in the manufacture of Aerosol products, Foam Products, Fire Extinguishers, Refrigeration and Air-conditioning product manufacturers including Mobile Air Conditioners and its gas charging units, Metered Dose Inhalers, Manufacturers, Import & Export of compressors and persons having facilities to reclaim/destroy Ozone Depleting Substances are required to register with the SISI. The registration of the ODS consuming and handling units is mandatory as per the Gazette Notification.
