Productivity is an important factor for measuring project performance and related to the profitability of construction firms. Thus productivity measurement is critical to plan and assess project performance and should be able to reflect job process and context rather than outcomes from 'black box'. This research proposes a productivity measurement approach based on job cycle analysis and discusses findings from two case projects to which the proposed approach was applied.

To carry out the Montreal Protocol, South Korea has completely prohibited the use of CFC which is a main refrigerant since 2010, and the use of HCFC is planned to be prohibited from 2040. Therefore, it is expected that dependency on HFC as an alternate substance of HCFC will be increased. Since HFC which is one of main substances causing global warming phenomenon may have a harmful influence on climate change, legal and institutional measures for totally managing HCFC and HFC are required. Therefore, in this study, the refrigerant management systems in EU, USA and Japan have been considered in three aspects, such as the legal system for refrigerant management, the management and regulation limits for products using refrigerant, and the reduction policies and trends, centering on HCFC and HFC which are international regulation and reduction objects. EU environmental law regulates over the entire process for ozone depletion substances, such as production, import, export, use, market release, recovery, landfill and decomposition thereof. The united states regulates forming agents, labeling agents or the like, pursuant to Article 608 of the Federal Clean Air Act (air conditioning and automobiles), and in the case of the state of California, PFC and SF6 including HFC are defined as high GWP, and separately classified and managed. Unlike EU and USA, Japan is characterized by applying the Freon recovery and decomposition law for totally managing the Freon-based gas such as CFC, HCFC and HFC, and regulations on the refrigerant recovery and decomposition for each product are also specified in separate law related to the recovery of End-Of-Life (EOL) home appliances and vehicles.

Hydrofluorocarbons (HFCs) emerged as alternative refrigerants after chloro fluorocarbons (CFCs) and hydro-chloro fluorocarbons (HCFCs) were identified as substances requiring control by the Montreal Protocol on Substances that Deplete the Ozone Layer. However, because the Kyoto Protocol considered HFCs as greenhouse gases, and their impact on climate change has been increasing, major developed countries have been strengthening the existing level of regulations related to the use of HFCs as refrigerants. In addition, South Korea has also passed various legislations relating to refrigerant management, in the form of policies such as the Wastes Control Act, the Act on Control etc. of the Manufacture of Specific Substances for the Protection of the Ozone Layer, the Clean Air Conservation Act, and the Act on Resource Circulation of Electrical and Electronic Equipment and Vehicles. However, reports indicate that these regulations have not been followed effectively due to the lack of a specific system relating to the phased management of production, use, and disposal of refrigerant materials. In order to identify and solve the problems relating to refrigerant management in South Korea, this study investigates the current state of refrigerant management in three separate phases: production, use, and disposal of refrigerants. Outstanding refrigerant management policies are also analyzed, using those enacted in the EU, United States, and Japan as examples, and these are then compared to regulations in Korea.

HFC계 폐냉매처리에 따른 온실가스 배출권 확보 방안

명소영 ( So-young Myung ),장완복 ( Wan-bok Jang ),김대용 ( Dae-yong Kim ) 한국폐기물자원순환학회(구 한국폐기물학회) 2019 한국폐기물자원순환학회 추계학술발표논문집 Vol.2019 No.-

HFCs는 CO₂보다 높은 GWP를 가지는 주요한 온실가스로 냉매로서 주로 사용되고 있으며, 오존층파괴를 막기 위한 Montreal Protocol에 의거하여 생산 및 소비가 제한되는 HCFCs 물질에 대한 대체물질로서 자리매김하면서, HFCs 수요는 급증하게 되었다. 이에 오존층 보호를 위한 조치가 기후변화를 가중시키는 결과를 초래하게 되는 사태가 우려되었고, 마침내 2016년 HCFCs 물질뿐 아니라 HFCs 물질까지도 생산 및 사용을 제한하는 “키갈리 의정서”가 채택되기에 이르렀다. 기후변화협약을 통하여 Paris Agreement가 발효(2016. 11.4) 되고, HFCs 물질 생산 및 사용이 제한되는 키갈리 의정서까지 발효(2019.1.1.) 됨에 따라, 선·개도국을 막론하고 기후변화협약 상의 의무이행과 키갈리 의정서 상의 제약을 극복해야 하는 상황에 처하게 된 바, 세계 각국은 HFCs 배출 및 사용저감을 위한 노력을 경주하고 있으며, 우리나라도 이러한 국제정세를 반영한 진지한 대책이 마련될 필요가 있다. 우리나라는 2016년 현재 HFC계 냉매로부터 약 9,080천 tonCO₂eq./yr의 온실가스가 배출되고 있으며, 같은 해 HFC계 폐냉매 회수량은 221 ton HFCs/yr로 보고되고 있다. 회수된 폐냉매가 모두 HFC-134a이며, 100% 처리된다고 가정할 때 폐냉매 처리로 인한 감축량은 287,300tonCO₂-eq/yr로 추산되며, 이는 냉매로 인한 배출량의 약 3%에 해당된다. 이렇게 폐냉매처리율이 낮은 주요한 이유로는 폐냉매처리 비용이 담보되지 않기 때문인 것으로 조사되고 있다. HFC계 폐냉매 처리를 활성화하기 위해서는 폐냉매 처리에 대한 법적 규제를 강화하는 방법을 생각해 볼 수 있으나, HFC계 폐냉매 처리 실적에 따른 인센티브 방안도 생각해 볼 필요가 있다. 인센티브를 제공하는 방법에 있어서 보조금과 같은 고전적인 방법 외에 배출권 거래시장과의 연계를 통한 방법도 생각해 볼 수 있다. 보조금의 경우, 정부 예산에 대한 부담을 가중시키게 되지만, 배출권 시장과 연계하여 배출권 수익창출로 이어지게 하는 경우, 폐냉매처리 실적을 인정함에 있어서 검증이라는 제도적 장치를 활용할 수 있는 바, 처리실적에 대한 신뢰성을 높일 수 있으며, 배출권 시장 안정화에 도움을 줄 수 있기 때문이다. 본 연구에서는 국내 배출권 시장제도 내에서 HFC계 폐냉매처리에 따른 온실가스 배출권 확보 방안을 제안해 보고자 한다.
