1. ODS Consumption in Taiwan

    To comply with the Montreal Protocol and exclude trade restrictions on ozone depleting substances (ODS) for local industries, since 1992, the Taiwan government has been reporting ODS consumption data to the Ozone Secretariat of UNEP.


    Abiding by the Montreal Protocol's control measures, Taiwan's CFCs consumption was reduced to zero and HCFCs consumption has begun to reduce since 1996. The HCFCs consumption baseline was counted as 638.156 ODP tonnes in 1996 and reduced to 383 ODP tonnes in 2004. The HCFCs consumption in 2010 in Taiwan was 152.56 ODP tonnes, accounted to 24% of the HCFCs consumption baseline. It shows that Taiwan still complies with the control measures for developed countries in the Montreal Protocol. One of the methods for Taiwan to fulfill its reduction commitments under the Montreal Protocol is that the Taiwan EPA has executed the regulation for HCFCs to suspend certain specific uses step by step, including the ban of using HCFC-141b on PU foam blowing and electronics cleaning. And after 2011, , the Taiwan government has banned the use of HCFC-22 as refrigerants for production of window mounted air conditioners as well as the separation type below 7.1 kW. The ODS consumption data in Taiwan shows the only ODS producers in Taiwan ceased production of CFCs in 1996 and HCFCs in 2006. In 2010, the imported HCFCs consisted of 2,755 tonnes of HCFC-22, 0.325 tonnes of HCFC-142b and 3.02 tonnes of HCFC-123. And the only exported HCFC was 42 tonnes of HCFC-22. Since 1999, Methyl Bromide has been allowed to be imported and used only for QPS purposes in Taiwan. Sixty-three tonnes of Methyl Bromide were imported in 2010.

  2. 2010 statistics for Uses of HCFCs in Taiwan

    Based on Article 16 in the "Regulation for Consumption Management of Hydrochlorofluorocarbons" published by the Environmental Protection Administration, Executive Yuan(EPA), companies qualified to be allocated HCFCs quotas shall declare their actual use records to the Taiwan EPA by the end of the first month in the following season. After collection and analysis of data declared in 2010, the applications and amounts of HCFCs used are summarized as follows:


    The number of companies qualified for HCFCs quota allocations in 2010 was 65, which included 10 importers and 55 industrial users. The total declared HCFCs used in 2010 amounted to 129,093 ODP kg. The main application of HCFCs was as a refrigerant, which accounted for 91.8% of total uses (118,409 ODP kg), while PO foam blowing accounted for 8.2% (10,629 ODP kg). In 2010, none of the HCFCs used in cleaning processes were declared because HCFC-141b has been banned for use in this application. Taiwan has also banned using HCFC-141b for all PU foam blowing applications since 2011. Figure 1 shows HCFCs used in different applications. Clearly, use of HCFCs for cleaning processes and foam blowing are decreasing trends, while the use of HCFCs as refrigerants is gradually decreasing due to the availability of alternatives.


    Figure 1, HCFCs used in different applications



    In Taiwan foam blowing process after 2010 mainly used HCFC-22, and accounted for 10,629.48 ODP kg in 2010. The HCFCs used as refrigerants , according to manufacturers' declarations, was 68,250 ODP kg in refrigerants for newly produced equipment(accounting for 58% of total use), and 2,578 ODP kg in newly constructed facilities with refrigeration and air conditioner systems (accounting for 2% of total use). Details are listed in Table 1.



    Table 1, HCFCs Used in Refrigerant Applications in 2010




    In 2010, the HCFCs used for maintenance totaled 47,582 ODP kg, which accounted for 40% of total use. The maintenance uses in transportation(such as in trucks/vans or fishing vessels)accounted for 17%; centralized air conditioners/chillers accounted for 12%; refrigeration facilities and showcases accounted for 10%, others were 1%. The majority of HCFCs used for maintenance applications was HCFC-22.

    Based on the timeframe for ODS reduction, the consumption level of HCFCs shall not exceed 10% of the calculated baseline consumption level for HCFCs in Taiwan by 2015. After 2020, every year's consumption of HCFCs shall not exceed 0.5% of the baseline consumption level, and HCFCs use will be limited to maintenance purposes for equipment that is still in operation. In 2010, the maintenance uses for HCFCs was 47,582 ODP kg, which accounted for 7% of the the calculated baseline consumption level. If the HCFCs use statistics include users who bought HCFCs from suppliers and distributors, the estimated HCFCs uses for equipment maintenance would account for around 15%. It will be an arduous challenge to fulfill maintenance needs for equipment that is still in operation in 2020, especially since the upper allowance will be limited to 3,191 ODP kg in 2020. Therefore, for future HCFCs quota allocation tasks, the Taiwan EPA will strengthen the quota controls for HCFCs allocations for maintenance purposes. In the future, the Taiwan EPA will continue to provide information on the HCFCs alternatives to industries, and establish appropriate refrigerant recycling and refilling processes for air conditioners and refrigeration systems to reduce HCFCs emissions.
