Hydrochlorofluorocarbons (HCFCs) have always been considered as an interim solution to Chlorofluorocarbons (CFC) Phase-out, because of their lower Ozone Depleting Potential (ODP) which is between 5-10% when compared to CFCs. While the Global Warming Potential (GWP) of HCFCs is high (600-2,200 CO2-equivalent), it is much lower than that of CFCs (6,000-10,600 CO2-equivalent). The majority of HCFCs have a high GWP. Their phase-out through the introduction of lower GWP alternatives will therefore contribute significantly to climate change mitigation. Depending on the alternative selected, this contribution can be very significant or can be so deleterious and of such magnitude as to nullify the efforts a country is undertaking via other voluntary actions, such as efficient lighting or appliance replacement programmes to achieve energy savings. In 2007, the Parties to the Montreal Protocol agreed to accelerate the phase-out of HCFCs (initially targeted for 2040) largely because of the substantive climate benefits this would bring about. Parties operating under the Montreal Protocol’s Article 5(1) (mostly developing countries) may receive financial assistance from the Multilateral Fund for the implementation of the Montreal Protocol (MLF) to formulate their overarching strategy and prepare HCFC Phase-out Management Plans (HPMPs).The control steps under the adjusted Montreal Protocol for these parties are: i) “freeze” of HCFC production and consumption by 2013 (the baseline being the average of 2009 and 2010); ii) reduction of 10% by 1 January 2015; iii) 35% reduction by 2020; iv) 67.5% reduction in 2025; v) 97.5 reduction by 2030; and vi) 100% phase-out by 2040. Currently, UNDP is assisting developing countries and countries with economies in transition to comply with the HCFC consumption freeze and the 10% reduction targets. As the lead agency in 30 developing countries UNDP is supporting the preparation of their HCFC Phase-Out Management Plans (HPMPs). Combined, these countries represent 77% of the global consumption of HCFCs. UNDP also supports countries in the preparation of investment projects for the conversion of manufacturing processes to non-HCFC alternatives in the foam, refrigeration and air-conditioning, solvents and other sectors. HCFC elimination in those sectors can bring energy efficiency gains and significant climate benefits through proper selection of alternatives. In short, UNDP’s country assistance contains the following main elements:
