| Abstract |
‘Carbon-neutrality Assessment based on Technology Application Scenario (CATAS)’ provides an analysis of greenhouse gas (GHG)reduction effectiveness when applying carbon-neutrality technology to areas such as energy conversion, transportation, and buildingsat certain spatial levels. As for the development scope of the model, GHG emission sources were analyzed for direct GHG emissions,and the boundary between direct and indirect emissions are set according to the spatial scope. The technical scope included ninetechnologies and forest sinks in the transition sector that occupies the largest portion of GHG emissions in the 2050 carbon neutralscenario. The carbon neutrality rate evaluation methodology consists of four steps: ① analysis of GHG emissions, ② prediction ofenergy production according to technology introduction, ③ calculation of GHG reduction, and ④ calculation of carbon neutrality rate. After the web-based CATAS-BASIC was developed, an analysis was conducted by applying the new and renewable energy distributiongoals presented in the 「2050 Greenhouse Gas Reduction Promotion Plan」 of the Seoul Metropolitan Government. As a result ofapplying solar power, hydrogen fuel cell, and hydrothermal, the introduction of technology reduced 0.43 million tCO2eq of 1.49 milliontCO2eq, which is the amount of emissions from the conversion sector in Seoul, and the carbon neutrality rate in the conversion sectorwas analyzed to be 28.94 %. |
