Abstract

The paper using data on 114 countries during 1992–2004 identifies the major perpetrators of escalating global emissions. Using the LMDI decomposition technique, we examine the contribution of the major factors in changing the level of emissions. The effect of GDP on emission is found to be substantially more than that of population. However, the income effect shows high fluctuation over time, while the population effect has been roughly constant. The upper middle-income countries, particularly of Europe and Central Asia, despite high economic growth have reduced their emissions substantially, while in the countries of North America, East Asia Pacific and South Asia increase in income have been significantly accompanied by increase in emission. Apart from few low emitting countries, almost all others have been successful in increasing emission efficiency, but their energy efficiencies have not been remarkable. Although emission efficiency has been more instrumental in curtailing emission, in some cases the path of change in emission follows that of change in energy intensity. Thus, both energy and emission intensity have crucial roles in determining the level of emissions. It may be suggested that emphasis should be given on policies oriented towards sufficient counteractive energy and emission efficiencies before embarking on a path towards economic growth.

Notes

  1. In ‘IPAT’, it is considered that I = P × A × T.

  2. Birdsall (1992) has specified two mechanisms through which population growth could contribute to emissions. First, a larger population could result in increased demand for energy for power, industry and transportation, hence the increasing emissions. Second, population growth could contribute to emissions through its effect on deforestation. The destruction of the forests, changes in land use, and combustion of fuel wood could significantly contribute to emissions.

  3. The concept is similar to environmental Kuznets hypothesis.

  4. A notable among them is World Bank (2007) that provides a decomposition of the change in fossil fuel CO2 emissions between 1994 and 2004 for 70 countries.

  5. See data.un.org.

  6. See worldbank.org.

  7. Based on the World Bank classifications.

  8. Calculated from available UN data for 204 countries.

  9. Karakaya and Özcag (2005) in their analysis argued that the reduction in emissions of former Soviet Union countries is mainly due to the crisis experienced by them after gaining their independence; population effect is mainly stable, while with energy-saving and carbon-reduction plans most of the countries have improved their energy intensities. However, in some countries like Germany, Poland, Switzerland, etc. though the feature is not applicable, they have reduced their emissions.

  10. Except in case of Haiti, in the other three countries the combined effects of emission and energy intensities reinforce the negative effects of income and population.
