This study employed OLS and quantile regression as the method. A combined GTAP-E data, I-O, and the calculation of carbon footprint survey used in this study. The result shows that fuel light consumption and transportation are the most carbon footprint formers. Furthermore, household income determines the most carbon footprint.
