Energy Efficiency Can Eliminate 1/3 of Global Greenhouse Gas Emissions

Global Contribution of Each Technology to a Safe Emissions Level (%)

This figure shows the percentage of emission reductions each technology can contribute if we bend our emissions curve downwards to levels that prevent the worst impacts of climate change.
  • 2016 data show the potential roles of different technologies to bend global emissions down from their current trajectory to levels consistent with a 2-degree level of warming.

  • The data show that energy efficiency is the biggest solution, accounting for roughly one-third of necessary emissions reductions.

  • In the U.S. energy efficiency provides nearly 40% of the solution.
