Restraining energy–related CO2 emissions

  • The primary driver of increasing global CO2 emissions between 2000 and 2016 was economic growth, as global GDP expanded about 55 percent
  • Improving energy efficiency across economies (energy use per unit of GDP) helped slow the growth in emissions, while CO2 intensity of energy use remained fairly constant
  • As economic growth continues to drive CO2 emissions through 2040, efficiency gains and a shift to less CO2-intensive energy will each help substantially moderate emissions
  • As the world’s economy nearly doubles by 2040, energy efficiency gains and a shift in the energy mix will contribute to a nearly 45 percent decline in the carbon intensity of global GDP
