At the 21st General Assembly of the Parties in 2015, the Paris Agreement, which will be the basis of a new climate system in which all countries participate, was adopted from 2020, and a system in which all countries participate in GHG reduction was established to reflect their own circumstances. Korea should reduce a total of 276.5 million tons compared to BAU (850.8 million tons) in 2030, and the agricultural and livestock sector should reduce 1.6 million tons. In order to achieve this, this study was conducted because it was necessary to identify major greenhouse gas sources. The criteria for the year of use were divided into three stages: 5 years or less, 6 to 10 years, and 11 years or more, and 18 agricultural heaters actually used by farms were set, and gas from exhaust pipes was collected and analyzed. As an analysis device, a gas chromatography system (Agilent technologies 7890B) was used, and as a result of the analysis, the average carbon dioxide emission concentration was 971.83 μmol/mol for 5 years or less, 1,209.83 μmol/mol for 6 years or more and 10 years or less, and 1,268.5 μmol for 11 years or more. More samples will be required for accurate results, but when comparing each value, it is judged that there is a difference in carbon dioxide emission concentration depending on the year of use of the agricultural heaters.
