The International Maritime Organization is preparing for measures to reduce greenhouse gases from ships by designating them as the agenda of MEPC(Marine Environment Protection Committee). In order for the response to climate change, this Committee established working groups to prepare IMO strategy and reduction target on GHG reductions. The initial strategy on reduction of GHG emission from ships was reported to the committee and it was adopted as Res.MEPC.304(72). The initial strategy adopted at MEPC 72 aims not only to reduce carbon intensity by at least 40 percent by 2030, 70 percent by 2050 but reduce total annual GHG emissions by at least 50 percent by 2050. This strategy lists candidate measures that can achieve the goal of greenhouse gas reduction through strengthening technical measures and operational measures, and it is expected that these measures will have a significant impact on international shipping if adopted. The use of technology for energy efficiency improvement of ships can cause an increase in the cost of ship construction, and the management of energy efficiency to implement the operation measures is expected to burden administrative costs for monitoring, verifying and reporting greenhouse gas emissions from ships. However, market-based measures will have more significant impact on profit or loss depending on the management and reduction capability of GHG by its pricing carbon emissions. This study aimed to not only analyze economic impacts of technologies for reducing GHG emissions so that the benefits and costs can be estimated based on marginal abatement cost of effective GHG reduction technologies in order for the response to GHG regulations but propose the directions for the Korean shipping industry to prepare and move forward.
