Vehicle manufacturers surpassed the more stringent 2014 standards for greenhouse gas emissions for the third consecutive year, while model year 2014 fuel economy remains steady at the highest level ever recorded, according to the EPA.
The findings were included in two reports: the annual report on fuel economy trends and a report on the auto industry’s progress toward meeting GHG standards for cars and light trucks.
The Greenhouse Gas Manufacturer Performance Report concludes that for model year 2014, manufacturers are over-complying with the GHG standards by 13 grams of CO2 per mile, or about 1.4 miles per gallon.
The agency’s annual “Light-Duty Automotive Technology, Carbon Dioxide Emissions and Fuel Economy Trends: 1975 through 2015” report shows that fleet-wide model year 2014 fuel economy remained steady at the highest recorded level, 24.3 mpg, with truck fuel economy reaching a record high of 20.4 mpg label average. In the last 10 years, fuel economy has increased significantly, improving 5 mpg or 26 percent overall.
The agency estimates that, through 2014, the GHG emissions standards have resulted in reducing cumulative emissions by roughly 60 million metric tons of CO2. These standards will ultimately save purchasers of a new MY 2025 vehicle more than $8,000 in lifetime fuel costs. The program in total will save $1.7 trillion in fuel costs, will reduce US fuel use by 12 billion barrels of oil, and reduce greenhouse gas emissions by 6 billion metric tons.
The Fuel Economy Trends report tracks average fuel economy of new cars and SUVs sold in the US. While overall GHG emissions continued downward due to improvements in air conditioning and other advancements, this year’s report finds that overall fuel economy remains steady at 24.3 mpg in model year 2014.
Truck fuel economy reached a record high of 20.4 mpg label average, a 0.6 mpg increase from last year and the second largest increase in 30 years. However, on a fleet wide basis, this higher truck fuel economy was offset by a 5 percent increase in truck market share. In addition, the report finds that the market is adopting fuel-efficient technologies such as turbocharging and advanced transmissions at a faster pace than the EPA projected when the standards were finalized.
