Chuncheon according to the IPCC guideline, and they increased from 1,014,382 ton-CO2 in 2000 to 1,084,914 ton-CO2 in 2009. Using BAU scenario GHG emissions in 2020 was estimated to be 1,518,526 ton-CO2, which increase approximately 40% from those for 2009. Six reduction methods were applied in this study, including solar power generation, substitution of LED lights, individual and families' energy reduction efforts, cogeneration of incinerator, and expansion of natural gas line. Estimated total reduced GHG emission was 174,340 ton-CO2.
