As carbon neutrality has recently emerged as a global issue, the carbon neutral roadmap of MOF has been established and various strategies have been proposed to achieve carbon neutrality in the entire marine industry. The port sector is also included in the target for greenhouse gas reduction, but emissions are not being measured due to limitations in data collection and no inventory construction. For building a carbon-neutral port, it is essential to calculate and forecast emissions and set reduction targets. Accordingly, in this study, CO₂ emitted from domestic port equipment was calculated according to the IPCC Guildeline's emission calculation method, and future emission was estimated. As a result of the analysis, about 420,000 tons of CO₂ was emitted based on the cargo volume in 2020, and emissions are expected to continue to increase in proportion to the increase and about 720,000 tons will be emitted by 2050. In order to achieve carbon neutrality of the port, it needs to promote emission reduction by converting the power source for oil-based equipment to eco-friendly fuel. Also container and miscellaneous ports which require complicated cargo handling need to effort to reduce CO₂.

The rapid climate change is strengthening carbon emissions regulations internationally. Korea is strongly pressed to accept the obligation to reduce greenhouse gases as one of the United Nations Framework Convention on Climate Change. This article analyzed the Granger causalities among environmental regulation, economic growth, electricity consumption, and CO₂ emission in Korea, using unit root test, cointegration test, and vector error correction model. As the results, environmental regulation has shown the bidirectional causalities with electricity consumption and CO₂ emission, while being unilaterally affected by economic growth in the long-run and strong relationship. Economic growth has affected electricity consumption, CO2 emission, and environmental regulation in the long-run, in the complex structure of the unilateral and short-run causality with electricity consumption and the bidirectional causality with CO2 emission. The policy implications will be as follows: ① environmental regulation should induce sustainable growth through encouraging technological innovation relating to CO2 reduction and productivity enhancement. ② Responding to the international CO2 reduction regulation, the synthetic policy initiatives will be considered to make synergy effects among policies relating to economic growth, electricity consumption.

온실가스 감축에 대응하기 위해서 CCS기술이 지구온난화 문제를 해결하는 중요한 기술로 부각되고 있다. $CO_2$ 포집기술 중 습식법에는 대표적으로 아민, 암모니아, $K_2CO_3$와 같은 흡수제를 이용한 연구가 진행되고 있다. 본 연구에서는 $CO_2$ 포집기술 중 하나인 $K_2CO_3$ 수용액을 이용하여 Bench급 $CO_2$ 포집설비에 대한 성능을 파악하기 위한 일환으로 15% $CO_2$를 공급하여 $CO_2$ 포집 안정화 시험을 진행하였다. 압력변화 및 단수 변화를 하여 실험을 진행하였고, 흡수탑 후단의 $CO_2$ 농도를 측정하여 $CO_2$ 포집 성능을 파악하였다.

This paper shows the positivistic approach for analyzing the effect of ICT on the reduction of greenhouse gas (GHG) emission. The real-time navigation was selected for the ICT based service in this research, and the CO2 reduction ratios of the optimized routes in the navigation were compared with the reduction ratios of the shortest routes in existing navigations. The results of experiments showed the driving based on the optimized routes has more reduction effects than the driving on the basis of the shortest routes. Also, new evaluation method for GHG emission was suggested by the quantification and monitoring approaches on the basis of the Clean Development Mechanism (CDM) in this paper. The results of this paper can be used as a preliminary research for the effect of ICT on the reduction of GHG emission. The evaluation method which suggested in this paper will be suggested to CDM as the new standard for the reduction of GHG emission in the transportation field as well.

In this paper, the reduction amount of CO2 due to the virtual international video-conference organized by ITU in order to reduce the greenhouse gas (GHG) is calculated. The comparison is made with the case of off-line conference. In the symposium organized by ITU, "The power of ICTs to save The planet", held on September 2009 the participants were highly encouraged to attend the symposium through video-conferencing for the reduction of GHG. As a result, 46 foreign participants and 16 among 170 domestic participants have attended at virtual video-conference, which resulted in about 94.7 ton of CO2 emission reduction. This international symposium firstly tried in conjunction with online and off-line has drawn a big attention in the aspect of global warming. Definitely such ITU's trial will make significant impacts on the holding of other international symposiums and forums.

The policies and researches for the reduction of greenhouses gases have been performed according to"Paris Agreement". Because South Korea is the $6^{th}$ biggest greenhouses gas emitter in the world, the Korea government has prepared the strategies for the reduction of greenhouse gases. The development of CCUS (Carbon Capture Utilization and Storage) technology is necessary to reduce greenhouse gases. Therefore, the CCUS has been studied by many contries in the world. In this work, the trends of CCUS technologies R&D has been shortly investigated.

As global warming accelerates, greenhouse gas reduction becomes more important. Carbon dioxide dry reforming is a promising green-house gas reduction technology that can obtain CO and $H_2$ which are high value-added materials by utilizing $CO_2$ and $CH_4$ which are greenhouse gases. However, there is a significant coking problem during operation of the dry reforming reactor. Because the carbon dioxide dry reforming is a strong endothermic reaction, the temperature of the reactor drops near the reactor inlet and causes coke formation. To solve this problem, it is important to ensure that the reaction takes place in a temperature range where coke production is minimized. In this study, we proposed a design method that can maintain reaction temperature in the region where the coke is rarely generated by using the new catalyst configuration method. The design method also optimizes the reactor by solving the optimization problem which minimizes the reactor length for a given reaction conversion by using the fuel flow rate, catalyst density, and output temperature by section as optimization variables.
