South Korea must submit its targets for greenhouse gas reduction by 2030 to comply with the Paris Agreement. While South Korea’s government has announced a roadmap for achieving greenhouse gas reduction targets by 2030, issues are present regarding the methodology used to set reduction targets, select the reduction method, and estimate the potential emissions reduction in the building sector. Accordingly, the present study identified the limitations based on an analysis of the roadmap and suggested an improvement plan for each limitation. To improve the roadmap, the methodology used to set emissions targets was changed from business-as-usual (BAU) to the absolute emissions method, the Intergovernmental Panel on Climate Change (IPCC) guidelines were applied to estimate greenhouse gas emissions, and methodology for determining emissions targets by year was proposed. The reduction method has been proposed abstractly, and five methods have been suggested: Energy consumption by building age and establishment of gross floor area for cooling/heating, supply status for each type of lighting, estimation of reduction amount through supply of LED lighting, reduction amount estimation by analyzing current supply status data for home appliances and office equipment, proposal of methodology for improvement of duplicate estimation for building energy maintenance systems (BEMS), and estimation of reduction potential by applying efficiency improvement in power generating equipment.

Business As Usual

The supply rate goal for new and renewable energy has been set to 20% by 2030 through the expansion of biogas production. The goal to reduce CO2 and greenhouse gas emissions by 37% below the business-as-usual (BAU) level of 851 million by 2030 was set by the Korean Government. However, biogas from corresponding treatment facilities is not used for the purpose of energy production, but is incinerated to raise the temperature of digesters. This study aimed to conduct a simulation of a solid oxide fuel cell (SOFC) hybrid plant using actual biogas operation data, analyzing annual performance. The 2450 kW SOFC system was set to its maximum capacity, with the available amount of biogas and the heat of the exhaust gas used to heat the anaerobic digester, but the amount of digester heat decreased in summer because of high air temperature. Up to 55% of total power usage could be produced via biogas, and a 45% reduction in CO2 was achieved.

New Buildings

South Korea is implementing policies to save energy and reduce greenhouse gases. As presented in the 4th report of the Intergovernmental Panel on Climate Change (IPCC), buildings have high potential for reducing greenhouse gases, and energy consumption in buildings is actually increasing. Buildings can be classified into the home, commercial, and public sectors. Among these, effects of the greenhouse gas reduction policy for residential buildings, which correspond to the home sector, are difficult to expect because they depend on voluntary participation. An analysis of the related practices showed that the potential greenhouse gas reduction until 2014 is 1,314 tCO2/yr, but the expected greenhouse gas emissions of residential buildings constructed only this year (2014) amount to 37,984 tCO2/yr. Greenhouse gas reduction effects in residential buildings are difficult to expect from current practices. Therefore, practical programs to improve energy efficiency for existing and new buildings are required.

Business As Usual

Purpose – Scenarios have become a vital methodological approach in business as well as in public policy. When scenarios are used to guide analysis and decision-making, the aim is typically robustness and in this context we argue that two main problems at scenario set level is conservatism, i.e. all scenarios are close to a perceived business-as-usual trajectory and lack of balance in the sense of arbitrarily mixing some conservative and some extreme scenarios. The purpose of this paper is to address these shortcomings by proposing a methodology for generating sets of scenarios which are in a mathematical sense maximally diverse. Design/methodology/approach – In this paper, we develop a systematic methodology, Scenario Diversity Analysis (SDA), which addresses the problems of broad span vs conservatism and imbalance. From a given set of variables with associated states, SDA generates scenario sets where the scenarios are in a quantifiable sense maximally different and therefore best span the whole set of feasible scenarios. Findings – The usefulness of the methodology is exemplified by applying it to sets of storylines of the emissions scenarios of the Intergovernmental Panel on Climate Change. This ex-post analysis shows that the storylines were not maximally diverse and given the challenges ahead with regard to emissions reduction and adaptation planning, we argue that it is important to strive for diversity when developing scenario sets for climate change research. Originality/value – The proposed methodology adds significant novel features to the field of systematic scenario generation, especially with regard to scenario diversity. The methodology also enables the combination of systematics with the distinct future logics of good intuitive logics scenarios.
