fuel combustion. Positive values for this factor in Figure 1 imply increasing use <strong>of</strong> electricity instead <strong>of</strong>other energy carriers (taking into account that the efficiency <strong>of</strong> condensing power production is usuallyquite low). Negative values would imply an opposite direction <strong>of</strong> change, i.e. technological changes suchas switch to combined heat <strong>and</strong> power (CHP) production instead <strong>of</strong> separate heat <strong>and</strong> electricityproduction.The third factor, FEC/GDP-factor, refers to the energy intensity <strong>of</strong> the whole economy. This can beinfluenced by several reasons such as changes in the industrial structure from energy intensive to lessenergy intensive industrial branches, change from industry towards services in terms <strong>of</strong> GDP shares, ortechnological <strong>development</strong> inside energy- consuming fields <strong>of</strong> the economy. Negative values for thisfactor in Figure 1 imply that India has decreased the energy intensity due to the reasons provided above.Positive values would imply an increasing effect to CO 2 emissions due change towards a more energyintensive structure <strong>of</strong> the economy.The fourth factor, GDP/POP-factor refers to the amount <strong>of</strong> economic activity per capita which can beinfluenced foremost by economic growth. The positive values for this factor in Figure 1 imply thatcontinuous economic growth per capita has increased CO 2 emissions. Negative values would imply adecreasing effect to CO 2 emissions due to decreasing GDP per capita.The fifth factor, POP-factor refers to change in the amount <strong>of</strong> population which is influenced by birth<strong>and</strong> death rates as well as by international migration. The positive values for this factor in Figure 1 implythat quite fast population growth has considerably contributed to the increase <strong>of</strong> CO 2 emissions fromfuel combustion in India. Negative values would imply a decreasing effect to CO 2 emissions due todecrease in the amount <strong>of</strong> population.The last set <strong>of</strong> bars shows the total change <strong>of</strong> CO 2 emissions in India as a sum <strong>of</strong> the five factorspresented above. Between the years 1973 <strong>and</strong> 1980 the absolute CO 2 emissions from fuel combustion hasincreased quite slowly, but during the time periods 1973-1990, 1973-2001 <strong>and</strong> 1973-2007 the increase inemissions has been faster. The shift to fossil fuel use, decreased efficiency <strong>of</strong> energy transformationchain, economic growth per capita <strong>and</strong> population growth have contributed to CO 2 emission growth.These factors have overrun the decreasing factor <strong>of</strong> the reduction <strong>of</strong> energy intensity <strong>of</strong> the economyresulting in a considerable increase <strong>of</strong> CO 2 emissions.3. ResultsThe CO 2 emissions <strong>and</strong> emissions per capita <strong>of</strong> the economies under investigation are presented in Fig.2. The data is from IEA (2009). In the statistics have data for China, India <strong>and</strong> Brazil starting from 1971<strong>and</strong> for Russia only starting from 1990. The changes in the emissions show quite different <strong>trends</strong>indicating the differences in economic processes in these countries. The factors behind these different<strong>trends</strong> are analysed using decomposition analysis.472
