Abstract
Recently, researches start to analyze subjective happiness index. This study examines the effect of environmental protection on happiness after eliminating the effect of economic factor such as Gross domestic products and unemployment. We analyze four environmental indices: local pollutants of suspended particulate matters (PM10) and sulfur dioxide (SO2) and global environmental indices of energy use and carbon dioxide. The result implies that only the deterioration of pollution level of PM10 and SO2 have a negative effect on happiness, and reduction of these pollutants contribute to improve happiness.
