Transportation’s Role in Reducing U.S. Greenhouse Gas Emissions

The report, while making no specific recommendations, analyzes the full range of strategies available to reduce transportation’s greenhouse gas emissions. Among specific findings:
• More fuel efficient gasoline vehicles could reduce per-vehicle emissions by 8 to 30 percent, hybrid vehicles 26-54 percent, and plug-in hybrids 46-75 percent.
• More direct routing of airline flights using NextGen technology and more efficient takeoffs and landings could reduce aviation greenhouse emissions by up to 10 percent by 2025.
• Reducing the number of vehicle-miles traveled through a combination of strategies, including improved public transportation, coordinated transportation and land use strategies, and greater opportunities for walking and biking – practices emphasized in the Department’s livability initiative – could reduce transportation greenhouse emissions 5 to 17 percent by 2030.
