The graph on the right shows changes in global energy-related emissions between 1971 and 2009. Also plotted are changes in world population, world GDP per capita, energy intensity of world GDP, and carbon intensity of world energy use. Over this time period, reductions in energy intensity of GDP and carbon intensity of energy use have been unable to offset increases in population and GDP per capita. Consequently, energy-related emissions have increased. Between 1971 and 2009, energy-related emissions grew on average by about 2.8% per year. Population grew on average by about 2.1% per year and GDP per capita by 2.6% per year. Energy intensity of GDP on average fell by about 1.1% per year, and carbon intensity of energy fell by about 0.2% per year.
