UNIDO plans, develops and implements national and sector-wide ozone-depleting substances (ODS) phase-out plans in developing countries to ensure their compliance with the Montreal Protocol. Since 1992, UNIDO has helped in the phasing out of more than one-third of ozone-depleting substances in the developing world.
UNIDO works to encourage the adoption of sustainable industrial solutions by converting and upgrading production lines of companies of all sizes. Interventions target particularly the foam, refrigeration, air conditioning, aerosol, solvent and healthcare sectors, as well as fire protection and agro-industry. In all areas, the introduction of new ozone-friendly technology and equipment is coupled with training on technology use and safety.
In line with its holistic approach to tackling ODS phase-out, UNIDO further supports governmental institutions with the strengthening of regulatory frameworks and the monitoring of ODS consumption.
UNIDO has completed over 1,340 Montreal Protocol projects through the Multilateral Fund, the Global Environment Facility (GEF) and through bilateral contributions. Currently, it is implementing hydrochlorofluorocarbons (HCFC) phase-out management plans in 70 countries.
With chlorofluorocarbons (CFCs) successfully addressed under the Montreal Protocol, the current major challenge pertains to the phase-out of HCFCs, which are predominantly used in the foam, refrigeration and air conditioning sectors. The most common alternatives to HCFCs are hydrofluorocarbons (HFCs). Although HFCs are non-ODS, they have a high Global Warming Potential (GWP). Therefore, the Unit seeks to avoid the use of transitional substances, such as HFCs, and opts for the use of long-term low-GWP solutions whenever possible.
Chemicals on the list of controlled substances under the Montreal Protocol include, amongst others, CFCs, halons, HCFCs and methyl bromide, and are collectively referred to as ODS. Most of them are also very potent greenhouse gases. The Montreal Protocol aims at completely phasing out the production and use of these substances and UNIDO is supporting a large number of countries to achieve this goal.
One example of UNIDO's interventions leading to climate impact, are projects focusing on the refrigeration servicing sector. These projects include introduction to and training in good service practices, as well as the provision of necessary equipment to reduce refrigerant leakages. These activities directly reduce emissions of gasses that both deplete the ozone layer and contribute to climate change. Additionally, improved service methods have a positive impact on energy consumption in sectors that usually account for substantial energy consumption.
