The U.S. industrial sector remains the leader in greenhouse gas emission reductions relative to other sectors, with an overall 12 percent decline since 1990. By using cleaner technologies, implementing energy efficiency initiatives, and incorporating sustainable business strategies, the sector is poised to continue reducing CO2 emissions even as industrial production rises. By contrast, CO2 emissions from the transportation, residential, and commercial sectors have all increased since 1990; collectively, CO2 emissions from those sectors rose by 20 percent through 2011.
