ACEEE’s Call to Action for Energy Efficiency

View our Call to Action

Through energy efficiency, the United States can halve domestic energy use and associated greenhouse gas emissions by 2050. This ambition, vital to preventing the worst effects of climate change, will not be realized without bold mobilization of efficient technologies and strategies. ACEEE is committed to meeting this urgent challenge. Our Call to Action lays out our vision for tackling climate change and the milestones we aim to reach by 2030. We document our progress to meeting those objectives in our annual report and other impacts highlighted here.

    • Helped set new U.S. product efficiency standards, which will avoid three billion metric tons of carbon dioxide emissions by 2030 and save hundreds of billions of dollars.
    • Led efforts to hike heavy-duty vehicle fuel economy standards, which will reduce average fuel consumption and greenhouse gas emissions of new trucks and buses by 37% from 2010 levels.
  • 2000–2009
    • Led efforts to establish CAFE provisions (2007) and heavy-duty fuel economy standards, spurring an increase in the average new car’s fuel economy from 20.6 miles per gallon in 2007 to 24.9 mpg in 2017, to a projected 36.0 mpg in 2025.
    • Led efforts to expand appliance standards to 23 additional products, including light bulbs, through 2005 and 2007 U.S. legislation.
  • 1990–1999
    • Helped launch the voluntary ENERGY STAR® program, which helps consumers find energy-efficient products and improves the efficiency of buildings and homes.
    • Led efforts to include lamp, motor, and HVAC standards in the Energy Policy Act of 1992, which will achieve cumulative energy bill savings of $340 billion by 2035.
  • 1980–1989
    • Led efforts to develop and adopt U.S. energy efficiency appliance standards, which now save a typical household about $500 each year on utility bills.
    • Played key role in defending and expanding the Department of Energy’s energy R&D programs.
