Decomposition of SO₂, NO_x, and CO₂, Emissions from Energy Use of Major Economic Sectors in Taiwan

Abstract

In this paper we use the Divisia index approach to decompose emission changes of SO2, NOx and CO2 from major economic sectors in Taiwan during 1980 to 1992. The study highlights the interrelationships between energy use and environmental quality, and provides insights for policy making. The emission changes are decomposed into five components-pollution coefficient, fuel mix, energy intensity, economic growth and industrial structure. Of all components analyzed, economic growth had the largest positive effect on emission changes for Taiwan's major economic sectors. Emissions of SO2 in industry and other sectors showed a decreasing trend due to fuel quality improvements and pollution control. However, NOx and CO2 emissions increased sharply in all sectors. Comparisons were also made with Germany, Japan and USA. This study hay shown that improvement in energy efficiency, pollution control and fuel substitution are major options to reduce SO2, NOx and CO2 emissions.

Decomposition Analysis of CO2 Emissions from Coal - Sourced Electricity Production in South Africa

“…IDA applies the index number concept in decomposition, and it has been universally used by scholars. For example, Lin and Chang (1996) applied the Divisia index approach to decompose emission of SO 2 , NO x and CO 2 from major economic sectors in Taiwan during 1980 to 1992. They revealed that economic growth had the leading positive effect on emission changes.…”

China's Dilemma: Economic Growth, the Environment and Climate Change

“…Only a few studies address sulphur dioxide emissions (Lin and Chang 1996;Shrestha and Timilsina 1997;Viguier 1999); among these, two (Shrestha and Timilsina 1997;Viguier 1999) address the emission intensity of individual energy sources, including coal, as a constant over time and focus only on changes in the energy mix-that is, the inter-energy composition of oil, gas, coal and non-fossil fuel energies. Lin and Chang (1996), however, find a continuous decrease in pollution intensity and attribute it to substitution for imported low-sulphur coal and 'desulphurisaton' of fuel oil, in the case of Taiwan. No study has, however, been done from the perspective of a clean future for fossil-fuel energy, and coal in particular.…”

The Determinants of Sulfur Emissions from Oil Consumption in Swedish Manufacturing Industry, 1976-1995

“…Labor price index Energy price index Sources: IEA (1990, 1992) and Statistics Sweden (1981, 1985, 1989, 1992, and 1996 18 The t-value of -1.55 corresponds to a p-value of 0.1465.…”

“…There are several studies done on carbon dioxide with this method, e.g., Ang and Choi (1997) and Casler and Rose (1998). Lin and Chang (1996) did a study on energy-induced gas emissions with respect to sulfur in Taiwanese industry. However, earlier decomposition analyses were limited in their direct policy conclusions; i.e., they did not relate emissions-changes to actual economic factors, such as tax changes and emissions-related regulations.…”
