Korea’s greenhouse gas emissions in 2011 totaled to 697.7 million tCO2. This is a 4.5% increase from the previous year and can be explained by steel production and thermal power generation as the key factors. Emissions from the steel industry and thermal power generation increased by 14.1 million tons and 7.3 million tons, respectively, compared to the previous year, which is equivalent to 47.0% and 24.2% of the total increase in greenhouse gas emissions, respectively. Total greenhouse gas emissions have been continuously increasing since 1990, excluding a considerable decrease during the economic recession of 1998. Current emissions are a 136% increase compared to the emissions of 295.7 million tCO2 in 1990.
Greenhouse gas emissions for 2011 consist of 89.4% CO2, 4.2% CH4, 2.7% SF6, 2.1% N2O, 1.2% HFCs, and 0.4% PFCs. The proportion of carbon dioxide emissions has increased from 85.7% in 1990 to 89.4% in 2011. There was a significant decrease in methane, from 10.1% in 1990 to 4.2% in 2011, due to a decrease in agricultural land and implementation of waste reduction measures.
Emissions by sector consist of 85.7% from energy, 9.1% from industrial processes, 3.2% from agriculture, and 2.1% from wastes. Emissions from fuel combustions make up 98.7% of the energy sector, which is equivalent to 86% of total national emissions, and has increased by 5.1% compared to the previous year. The fuel combustion sector consists of 44.7% from energy industries, 31.1% from manufacturing and construction, 14.4% from transport, and 9.9% from other areas. In terms of the increase in emissions by sector, the energy sector, industrial processes, and wastes showed an increase of 5.1%, 1.1%, and 2.5%, respectively, and the agricultural sector showed a decrease of 0.7%.
