The analysis of inequality using carbon footprint approach in Jambi and Indonesia

Human activity has been found to be the leading contributor to the rise in global emissions, particularly since the industrial revolution (IPCC 2013). Based on the fact that carbon dioxide emissions comes from economic sector which leads to global warming, research in household consumption is relevant to be done through its effect in increasing carbon footprints because household consumption has the greatest contribution to carbon dioxide emissions.
The objectives of the study are

  1. Determine the characteristic of Carbon consumption differ in terms of expenditure of households in Jambi and Indonesia,
  2. Which factors affect the household carbon footprint and how does role of rising affluence versus other drivers influence household emission,
  3. Study on the main contiributors (drivers) of CO2 emission inequality at the household-level and its link to expenditure inequality.
This research using Indonesian Input-Output (IO) table data, National Socio-Economic Survey (SUSENAS) 2016 and Global Trade Analysis Project Environmental Account (GTAP-E). Descriptive analysis method used in this study to describe the general carboon footprint based on consumption in Jambi and Sulawesi. In approach of calculating household-based carbon footprint calculated from the final consumption (Rp) by multiplied with the intensities of carbon from every sector (kg CO2/Rp), to analyze the factors affecting the carbon footprint in household use the linear regression method, for measuring basic in emission equity using in approach Gini Coefficient, and their index.
