Since 2006, the International Olympics Committee (IOC) has focused on implementing clean and sustainable energy practices while creating an infrastructure for the Olympics. In July 2015, the PyeongChang Organising Committee for the 2018 Olympic and Paralympic Winter Games (POCOG) released their 2018 Sustainability Framework to share their vision on a clean and sustainable Winter Olympic games. This was followed by a Sustainability Interim Report released in February of 2017 to detail the progress since the initial Sustainability Framework. In December 2017, POCOG released another report: the Sustainability Pre-Games Report. This report details POCOG's efforts and achievements that have been made towards the sustainability of the PyeongChang 2018 Winter Games as laid out in their initial 2015 Sustainability Framework report. POCOG hopes to go beyond their "zero emissions" goal using greenhouse gas reduction strategies focused in five areas: establishing green transport infrastructure, self-sufficient renewable energy, sustainable construction, minimization of carbon emissions, and green procurement. The following article is a summary of the efforts and achievements that POCOG has made as laid out in the Sustainability Interim Report and Sustainability Pre-Games Report.
