Analysis of Energy-Related Greenhouse Gas Emission in the Korea's Building Sector: Use National Energy Statistics

Every country in the world is striving to deal with climate change such as global warming and environmental pollution caused by greenhouse gas emission as well as the depletion of fossil fuel including oil, coal, gas, etc. Countries have set long-term greenhouse gas emission reduction targets in this effort. Korea announced its goal to reduce the national greenhouse gas in medium-and long-term by 25.7% of the observed value of 2030 greenhouse gas emission (BAU) in 2011, and set to reduce the greenhouse gas by 18.2% in the building sector. In addition, according to IPCC (Intergovernmental Panel on Climate Change), greenhouse gas emission in the building sector takes up about 19% of entire emission, a very high percentage along with 31% from the industry sector. This paper calculates the national and building sector greenhouse gas emission based on energy consumption statistics, in order for Korea to achieve Post-2020 greenhouse gas reduction target, predict building sector's greenhouse gas emission, and implement and reduction policy. The greenhouse gas emission from buildings is about 124.9 million ton CO(2)equivalent as of 2015, taking up about 20% of greenhouse gas emission in Korea's entire sectors, and decreased in 1998 from 105.0 million ton CO(2)eq in 1997. However, the greenhouse gas emission consistently increased from 119.3 million ton CO(2)eq in 2007 to 127.1 million ton CO(2)eq in 2010 and 127.3 million ton CO(2)eq in 2013.
