Abstract
본 연구에서는 2015년부터 시행된 온실가스 배출권 거래제도에 맞추어 상쇄(offset)제도의 구체적인 설계가 필요한 시점에서, 가정부문의 고효율 전자기기의 보급을 통해 확보할 수 있는 잠재 상쇄 공급량을 추정하였다. 분석대상 품목은 TV, 세탁기, 선풍기, 냉장고, 에어컨 등 다섯 가지 가전기기이며, 자기회귀시차분포모형(ARDL)을 통해 2016년부터 2022년까지의 고효율 가전기기의 보급대수를 추정하고, 효율 개선을 통한 전기 절감량과 이에 따른 탄소 환산율을 통해 최종적으로 잠재 상쇄 공급량을 도출하였다. 고효율 가전기기의 에너지 절감률을 각각 10%와 20%로 가정했을 때 2022년에 누적된 탄소 저감량은 361,899CO2t과 723,797CO2t으로 나타났으며, 에너지 절감량이 큰 순서로는 에어컨, 냉장고, TV, 세탁기, 선풍기 순으로 나타났다. 또한 에너지 소비효율 1등급 가전기기의 에너지 절감률이 20%라고 가정했을 때, 누적 탄소 저감량이 2015년에 비해 2022년에 약 316% 증가하는 것으로 나타났다.
A more detailed design of offset system is needed according to the emission trading system started in 2015. This study aims to estimate the supply of potential offset that can be secured by expanding high-efficiency household electric appliances. The target commodities for analysis are three different householding electric appliances: TV, washing machine, electric fan, refrigerator and air conditioner. By using the ARDL model, we estimated the coefficients of diffusion of these high-efficiency appliances from 2012 to 2022. Then, the potential supply of offset was drawn by calculating the amount of electricity saving by efficiency improvement and by applying the rates of carbon exchange. Supposing that the electricity savings rates of high-efficiency appliances are each 10% and 20%, the accumulated carbon decrement in 2022 was respectively 361,899CO2t and 723,797CO2t. The appliance that showed the biggest carbon decrement was air conditioner, and the second biggest was refrigerator and the next was TV, followed by washing machine, electric fan.
