Restraining energy-related CO2 emissions

  • Improving efficiency and decreasing the CO2 intensity of energy use help stem emissions as populations and GDP grow
  • China’s GDP rose about 1,000 percent from 1990-2015 but energy efficiency gains kept a rise in CO2 emissions to about 300 percent; efficiency gains and lower CO2 intensity will help emissions peak around 2030
  • OECD nations improved efficiency and CO2 intensity from 1990 to 2015, keeping emissions relatively flat; accelerating gains will help reduce emissions 20 percent by 2040
  • CO2 emissions in other non-OECD nations rose about 50 percent from 1990 to 2015, and are likely to increase 50 percent by 2040 despite a 40 percent gain in efficiency across these emerging economies
