The objective of this study is to examine the equilibrium relationship in the short and long term of energy consumption in Indonesia (ECI) and carbon dioxide emissions in Indonesia (CO2 EI) for the period of 1980-2014. The dependent variable is environment and CO2 emissions have been selected as an indicator for this variable while the independent variable in this study is energy consumption. In this study, quantitative method-based methodology has been selected. The quantitative method enable researcher to examine the relationship objectively using numbers, digits, and ratings as empirical evidence. In addition, the researcher used deductive reasoning to present the arguments. | Estimating the impact of energy consumption on carbon emissions using environmental Kuznets curve -
