4.2.1 Sustainability Theme 1: Low Carbon Green Olympics Climate change is the one of the major issue in international environment and closely related with the winter Olympics. In order to bring down the greenhouse gases, building design of the venues and construction were reflected with environmentally friendly aspects (POCOG, 2017). Moreover, plenty of the programmes have been promoting for participants to protect the environment with enjoying the beautiful nature of the Olympic city. Thus, in order to become an environmental Olympic games, “Low-Carbon Green Olympics (POCOG, 2017, p. 51)” has been established as a one of the sustainability theme (POCOG, 2017). The detailed plans are defined as “Reducing and Offset GHG Emissions”, “Building Green Transport Infrastructure”, “Designing and Constructing Sustainable Venues”, “Using Renewable Energy”, “Practising Green Procurement”, “Fostering Environmental Awareness”, “Communicating with Stakeholders” (POCOG, 2017). POCOG has put their vision as a “Carbon-Responsible Games (POCOG, 2017, p. 53)” and has been carrying out the different plans for cutting down the greenhouse emission while preparation and management the games. As the first Winter Olympics which make the goals to become a zero carbon emission as well as O2 PLUS, POCOG will try to reduce the overall greenhouse gases(1,596,000t CO2eq) until the termination of the Olympics. Therefore, basic strategies and greenhouse gas monitoring plan have been executed. Those systems and reports that stated about strategies and performances will be recorded as a legacy plan of the “Low Carbon Green Olympics” which build up the management experience and system (POCOG). 4.2.2. Sustainability Theme 2 : Stewardship of the Nature Gangwon Province where the Olympics are taking place is classified as vegetation preservation zone of 1st grade and 81% of the region is forests. Also, they have three wetland reserve and four sight preservation areas. Therefore, proactive action and effective counterplan should be considered as reliving the worries in environmental issues. Therefore, POCOG set the goals as the Stewardship of Nature for recovering the regions which are effected by the Olympics and for protecting the biodiversity. They categorized their activities as “Conserving Biodiversity”, “Restoring Ecology”, “Managing Air Quality and Noise, “Managing Waste” (POCOG, 2017, p. 67) One of their main actions for preserving the nature is “Restoring Ecology”. According to POCOG (2017), POCOG have started rehabilitation business to restore the destroyed mountains and forest which was devastated by the construction of Jeongseon Alpine Centre. POCOG will carry through on their bid statement cooperation with the Korea Forest Service that “create forests twice as large as the impacted area to compensate for the loss within protected area in Baekdudaegan Mountain Range (POCOG, 2017, p. 71)” . They have been formed Forty-five hectares (45ha) of reforestation in 2016. Also, 62 hectares of the reforestation will be continued from 2017 and 2018. After 2018, 67 hectares of the forests will be created and completed their project while recovering the 174 hectares of forests. 4.2.3. Sustainability Theme 3: Good Life Hosting the 2018 Winter Olympics will give the economic growth and social infrastructure for developing the Gangwon Province. New construction such as venues, athletes’ villages and media villages will remain as the legacy for the local community and road and railway will improve the quality of the local people. Based on advancement, POCOG made an effort to boost the locals to participate the Olympics with making the one of the sustainability theme “Good Life” that is classified as “Leaving Sustainable Olympic Legacy : Post-Games Use of Competition and Non-competition Venues, Transport Infrastructure”, “Building Local Infrastructure : Designation of Special Zones and Advancement of Tourist Guide System”, “Developing Local Economy : Better Quality Accommodation and Food Services” Especially for the “Leaving Sustainable Olympic Legacy”, Venues and other new constructions as the remaining legacy from the Olympics have been planned for using as a sports complex to the local residents as well as inducing the tourists. Thus, POCOG have made initiatives for using the structure when the Olympics are over. Firstly, among the 12 sports stadiums, 6 of the venus were newly built and rest of them finished to reconstruct for using as Olympics. Post Olympic plans have been organized for 9 venues out of the 12, but 3 of the stadiums still looking for its utilization after the competition. Secondly, the PyeongChang Olympic Stadium that will be used for opening and closing ceremonies will be created as Olympic memorial hall after demolishing stands and some parts. Lastly, the Olympic and Paralympic Villages and the Media Villages which were invested and built by the private sectors already finished to sell. Once the Olympics end, the renovation and reconstruction will be started for proving to public to better the condition of housing supply and community development (POCOG, 2017).
