Abstract
Preventing global warming caused by increased CO2 emissions is a major global problem. It is necessary to find and cultivate an efficient industry with a small amount of CO2 emissions and a great impact on the national economy. This article used input–output analysis to quantify the linkage effects on the Korean economy by dividing the Korean industries into 36 categories, according to the OECD (Organization for Economic Cooperation and Development) industrial classification criteria. In addition, the total amount of carbon dioxide emitted during the year was described by its criteria to compare how much of one industry emits carbon dioxide. The analysis shows that Korea still has an economic structure centered on traditional manufacturing and the characteristics of these industries include CO2 emissions. According to the result, in the construction industry, the carbon dioxide emissions are considerably high, but the linkage effects of the industry is small. By quantitatively analyzing the impact of an industry on the economy and carbon dioxide emissions generated in the production process, this study aimed to identify Korea’s eco-friendly and highly related industries with other industries and objectively present sustainable development.
Highlights
Since the Industrial Revolution, countries around the world have emitted huge amounts of greenhouse gases (GHGs) through development and advancement
The backward linkage effect is an influence generated by the input of intermediate goods into the product process owned by the industry, which means an attraction to all industries
Miller and Blair [54] interpreted that when the forward linkage effect is greater than 1, it is highly sensitive to the demand of intermediate goods from other industries, and when the backward linkage effect is greater than 1, it has an influence on supplying intermediate goods of other industries
Summary
Since the Industrial Revolution, countries around the world have emitted huge amounts of greenhouse gases (GHGs) through development and advancement. Global GHG emissions are projected to continue to increase from 52.7 Gt CO2 in 2014 to 65 Gt CO2 in 2030 and 87 Gt CO2 in 2050. The main cause of GHG emissions is carbon dioxide emitted from the raw material refinement process, which was measured at 36.2 Gt CO2 in 2015, accounting for 68% of global GHG emissions. The raw material refinement process directly affects industrial activities because industries cannot take action without the refined fuel. It is an environmental problem, but an economic problem. Highly dependent on energy imports and on international trade, is greatly affected by GHG emissions regulations
