Tóm tắt: The study employs structural decomposition approach based on Kaya identity and utilizes data from International Energy Agency (IEA, 2010) to analyze the relation between CO2 emission increase and GDP per capita, energy intensity of GDP, CO2 energy intensity and population in Vietnam. The research brings about the following outcomes: The rapid GDP increase (y/p) and high CO2 energy intensity (c/e) are two major factors causing high increase in CO2 emission even though GDP energy intensity (- e/y) continuously declined and population growth was lower than 1.67% yearly in 1986-2008. The economic structural change and the shift of fuel mix were the main forces driving GDP growth while suppressing CO2 emissions in Vietnam in 1989. The trend of c/e coefficient is due to the increase in fossil fuel dependency, economic structural change toward industrialization concentrating on manufacturing industries, a large inflow of FDI into manufacturing and construction industries without paying due attention to screening whether the acquired technology is environmentally friendly. Moreover, an increased number of vehicles and urbanization in Vietnam also boosted energy consumption. Consequently CO2 emission had risen. Therefore, improvement of energy efficiency incorporated with a shift in energy mix to renewable energy, and applying energy-saving and environment friendly technology (EFT) are the most important steps to curb CO2 emission. Keywords: Kaya identity, CO2 intensity, energy intensity.
