As interests in sustainability have been increasing and discussions of environmental issues are ongoing globally, the MICE industry (Meeting, Incentive Travel, Convention, and Exhibition), which is attracting attention as a high value-added industry, also became an important part of the sustainability domain. Consequently, there has been a rise in hosting 'green conventions', or 'green MICE' which are designed to minimize all the negative impacts on the environment such as energy and water consumption. At some point, a large number of studies had been conducted for the development of green conventions, but most of them mainly used empirical methods. Although the Ministry of Environment has presented guidelines and some domestic exhibition convention centers have implemented strategies, they are not enough compared to overseas countries. This study aims to examine the latest guidelines to supplement the guidelines of Korea's green convention. In this regard, the study will use a comparative analysis method among the current guidelines of convention centers in Australia (Sydney), Canada (Vancouver), and the U.S.A (Detroit and San Francisco) and draw up complementary directions. As a result, we could draw out common items in the facility management and event planning and operation section. Some items were similar in all convention centers, but others were included in the guidelines of few centers only. This research is sure to be the academic background for developing related practices and standards for the future green convention in Korea. In addition, this study will have value in terms of investigating sustainable management in the convention industry as the importance of sustainability in the tourism industry emerges.
