Energy consumption, CO2 emissions, and economic growth: evidence from Indonesia

Energy policy-makers in Indonesia are interested in the causal relationship between energy consumption, CO₂ emissions, and economic growth. Therefore, this paper attempts to analyze the short- and long-run causality issues between energy consumption, CO₂ emissions, and economic growth in Indonesia using time-series techniques. To this end, annual data covering the period 1965–2006 are employed and tests for unit roots, co-integration, and Granger-causality based on an error-correction model are applied. The results show that there is a bi-directional causality between energy consumption and CO₂ emissions. This means that an increase in energy consumption directly affects CO₂ emissions and that CO₂ emissions also stimulate further energy consumption. In addition, the results support the occurrence of uni-directional causality running from economic growth to energy consumption and to CO₂ emissions without any feedback effects. Thus, energy conservation and/or CO₂ emissions reduction policies can be initiated without the consequent destructive economic side effects.
