  • Emission trading schemes, exemplified by the EU Emission Trading Scheme, have been playing active roles in mitigating greenhouse gas emissions since the Kyoto Protocol employed an emission trading as one of the cost-effective mechanisms. The objective of this study is to investigate potential integration of forestry offsets in designing an emission trading scheme in South Korea. First, the study found feasible scopes in which forestry sectors can take part by analyzing five emission trading schemes: EU Emission Trading Scheme, Chicago Climate Exchange, New South Wales Greenhouse Gas Abatement Scheme, New Zealand Emission Trading Scheme, and Regional Greenhouse Gas Initiative. The rationale of including forestry offsets in a domestic emission trading scheme was derived from the fact that forestry offset credits can provide cost-effective ways for market participants to commit their emission targets and expand abatement activities through reducing greenhouse gases in other geographical locations as well as other industrial sectors. Even though forestry offset credits have risks induced by their technical complexities in terms of accounting, additionality, and leakage, the integration of forestry offset credits into an emission trading scheme would be able to provide positive opportunities both to forestry sectors and other industrial sectors. In addition, there are technical questions which need to be answered in order to maintain these opportunities.

  • 차랑 등의 수송연료인 휘발유나 경유에 일정비율을 식물에서 뽑아낸 신재생연료 즉 바이오 연료를 혼합하여 공급하도록 의무화하여 온실가스 배출을 줄이기 위한 신재생연료 혼합의무제도(RFS) 국내 시행방안과 관련한 공청회가 지난 2월 15일 서울교육문화회관에서 지식경제부 주최와 한국석유관리원 주관으로 개최됐다. 정부는 2020년까지 경유나 휘발유에 바이오 디젤 에탄올을 4~5% 섞게 하여 동 기간까지 온실가스 감축목표량 중 8~10%까지 달성한다는 계획을 세워놓고 있다. 하지만 녹색연대 등 민간단체들은 온실가스 감축 효과는 매우 불확실하며 특히 어떤 원료를 쓰느냐에 따라 오히려 기후변화를 악화시킬 수 있다는 주장과 산림훼손, 세계 곡물가 상승, 국내 유가 상승 등 많은 문제점들이 있음을 우려해 강하게 반대를 표명하고 있는 입장이다. 우리 협회에서도 곡물을 이용한 에탄올의 혼합의무가 시행되는 경우 옥수수 등 사료원료가격의 상승으로 가뜩이나 어려운 축산업의 경영상황을 더욱 약화시키게 될 것이 예견되는 바, 동 혼합의무제도의 시행을 적극 반대하는 대 국회 및 정부활동을 전개한 바 있다. 그 결과 지난 4월 17일 국회 지식경제위원회 법률심사소위원회에서는 신재생연료 혼합의무제도의 시행 시기를 2년간 유보하고 혼합의무연료에서 에탄올을 제외시키는 방안을 논의한 바 있어 향후 입법과정에 관심이 모아지고 있다. 이에 따라 본지는 이번 RFS의 국내 시행과 관련하여 어떠한 문제점들이 있는지 관련 업계 종사자의 글을 통해 알아본다.

  • In this paper, a portal system compatible with MRV regulation was designed to monitoring, reporting and verifying $CO_2$ emission and fuel consumption data from an international ship. A portal system supports monitoring and reporting task of international shipping companies and calculates national greenhouse gas inventory. EU MRV law, MRV discussions of IMO, responses of international shipping companies to ship energy efficiency and greenhouse gas regulation, and greenhouse gas statistics on international shipping were analyzed to drive portal system requirements. For ship energy efficiency and $CO_2$ emitted monitoring, a data collection module was designed based on on-board equipment, energy efficiency measuring device and navigation report. Data transfer module with easy management and minimized usage to transfer ship data to shore was designed. A portal system was designed to convert the collected data into the standard reporting format, perform monitoring, statical analysis, verification and auto report generation, and support national greenhouse gas inventory.

  • In this study, the humidity control effect of a counter-flow ventilator was analyzed in a greenhouse with high relative humidity at night in the winter season. A case of the counter-flow ventilator was 0.96 × 0.65× 0.82(W × D × H, m) and there were heat transfer element and two fans for air supply and exhaust in the counter-flow ventilator. Two counter-flow ventilators were used in this study and the setting humidity of the ventilators was 80%. The temperature and relative humidity at night(18:00-8:00) in the greenhouse were measured. In a greenhouse without a counter-flow ventilator, the average temperature and humidity was 14.9℃, 82.8%, respectively. When the counter-flow ventilator was operated, the corresponding averages were 15.1℃, 79.9%. The independent sample t test of monthly temperature and relative humidity showed no difference in temperature, and a significant difference in relative humidity with 1% of the significance level. Therefore, using the counter-flow ventilator helps to control relative humidity in greenhouse and increase yield.. And further research considering the pros and cons of using the counter-flow ventilator is needed.

  • Accurate assessment of greenhouse gas emissions is a cornerstone of every climate change response study, and reliable assessment of greenhouse gas emission data is being used as a practical basis for the entire climate change prediction and modeling studies. Essential, fundamental technologies for estimating greenhouse gas emissions include an on-site monitoring technology, an evaluation methodology of uncertainty in emission factors, and a verification technology for reductions. The closed chamber method is being commonly used to measure gas fluxes between soil-vegetation and atmosphere. This method has the advantages of being simple, easily available and economical. This study presented the technical bases of the closed chamber method for measuring methane fluxes from a rice paddy. The methane fluxes from rice paddies occupy the largest portion of a single source of greenhouse gas in the agricultural field. We reviewed the international and the domestic studies on automated chamber monitoring systems that have been developed from manually operated chambers. Based on this review, we discussed scientific concerns on chamber methods with a particular focus on quality control for improving measurement reliability of field data.

  • This paper introduces domestic and international trends and researches related with U-Greenhouse systems. USN (Ubiquitous Sensor Networks), along with the development of networks as well as science and technology, is a new computing paradigm which is the convergence of user-oriented physical activity space and virtual space of electronics and computing and also provides services according to change in surrounding environment at anytime and anywhere. The U-Greenhouse system is to apply USN to agricultural production, logistics and distribution management which are relatively insufficient to utilize IT technology. Thus, applying u-IT technology to agriculture can reinforces international competitiveness of the agricultural sector through the effects such as cost cutting as a rise in output, logistics and distribution management.

  • Globally, there is a collaborative effort to achieve global carbon neutrality in response to climate change. In the case of South Korea, greenhouse gas emissions are rapidly increasing, presenting an urgent situation that requires resolution. In this context, this study developed a thermal energy collection device named a 'steam trap' and created an AI model capable of predicting future electricity usage by collecting energy usage data through steam traps. The average accuracy of electricity usage prediction with this AI model was 96.7%, demonstrating high precision. Consequently, the AI model enables the prediction and management of days with high electricity consumption and identifies which facilities contribute to elevated power usage. Future research aims to optimize energy consumption efficiency through efficient equipment operation using anomaly detection in steam traps and standardizing energy management systems, with the ultimate goal of reducing greenhouse gas emissions.

  • 현재 국내 에너지산업은, 초고유가 및 온실가스감축 대응을 위한 에너지수요관리문제의 급부상, 에법에 의한 한국전력공사의 수요관리 투자계획수립자 재지정 문제, 전력수요관리 추진체계 개편 등 에너지부문에 다분히 도전적인 문제들이 놓여진 어려운 상황으로 여겨지나, 이는 반대로 수요관리 추진체계를 정립할 수 있는 좋은 기회라 판단된다. 따라서, 국내수요관리사업의 현황을 면밀히 분석하고, 해외 선진국의 사례 검토를 통해, 국내 전력산업에 적합한 효율적인 전력수요관리 추진체계 개편방안에 대한 연구가 필요하며, 이를 통해 수요관리 전문기관의 위상정립 및 역할강화 방안을 모색해야 한다.
