AB: Applying monthly sales and consumption data of coal, petroleum and natural gas, a monthly time series of carbon dioxide emissions from fossil-fuel consumption is created for Indonesia. These are then modeled with an autoregressive function to produce a quantitative description of the seasonal distribution and long-term pattern of CO2 emissions. Currently, Indonesia holds the 21st ranked position in total anthropogenic CO2 emissions among countries of the world. The demand for energy in Indonesia has been growing rapidly in recent years as Indonesia attempts to modernize and upgrade the standard of living for its citizens. With such a large population (a quarter of a billion people), the recent increase observed in the per capita energy use equates to a large escalation in total CO2 emissions. However, the economy and political climate is rather turbulent and thus emissions tend to fluctuate wildly. For example, Indonesia's energy consumption dropped substantially during the Asian economic crisis in the late 1990s. It is likely that the recent tsunami will also significantly impact energy consumption as the hard-hit Aceh region is the largest fuel-producing region of Indonesia. Therefore, Indonesia is a country whose emissions are more unpredictable than most countries that emit comparable levels of CO2. Complicating matters further, data collection practices in Indonesia are less diligent than in other countries with more stable economies. Thus, though CO2 emissions from Indonesia are a particular challenge to model, they are an important component to understanding the total global carbon cycle.
