Index Decomposition Analysis on Carbon Dioxide Emissions of Passenger Cars in Japan

Abstract

This paper mainly analysis the change by the Logarithmic mean Divisia index method on the emission of carbon dioxide deduced by passenger cars in Japan. Decomposition analysis is a method that analyzes the effects lead to the change of the emission of carbon dioxide. Based on this method, the analysis of the emission of passenger cars in recent years is done to explain the changes. It is found that the car number in advanced regions in Japan rises successfully every year and affects the carbon dioxide emission crucially and steadily. Population is another effect that brought in great emission at the time which in high speed of economic growth, yet the travel distance by passenger cars is decreased and does negative effect to the emission. Based on the result of this analysis, corresponding strategy such as restricting the use of cars and promoting public transportation is proposed.

Electric vehicles adoption challenges in Oman: a comprehensive assessment and future prospects for sustainable cities

“…The United States witnessed a 55% increase in electric car sales in 2022, capturing an 8% sales share (IEA, 2023). By 2030, it is projected that around 26% of new global car sales will be EVs, with an estimated addition of 58 million new self-driving cars to the global fleet that year (Ian, 2023). Oman aims for net-zero emissions by 2050, planning to transition to 79% electric vehicles (EVs) in its fleet by 2035.…”
