DOT, EPA Set Aggressive National Standards for Fuel Economy and First Ever Greenhouse Gas Emission Levels For Passenger Cars and Light Trucks

Release date: 04/01/2010

WASHINGTON - Responding to one of the first major directives of the Obama Administration, the U.S. Department of Transportation (DOT) and the U.S. Environmental Protection Agency (EPA) today jointly established historic new federal rules that set the first-ever national greenhouse gas emissions standards and will significantly increase the fuel economy of all new passenger cars and light trucks sold in the United States. The rules could potentially save the average buyer of a 2016 model year car $3,000 over the life of the vehicle and, nationally, will conserve about 1.8 billion barrels of oil and reduce nearly a billion tons of greenhouse gas emissions over the lives of the vehicles covered.

This action is one important step in fulfilling the Obama Administration’s commitment to moving towards a clean energy, climate friendly economy.

“These historic new standards set ambitious, but achievable, fuel economy requirements for the automotive industry that will also encourage new and emerging technologies,” said Transportation Secretary Ray LaHood. “We will be helping American motorists save money at the pump, while putting less pollution in the air.”

“This is a significant step towards cleaner air and energy efficiency, and an important example of how our economic and environmental priorities go hand-in-hand,” said EPA Administrator Lisa P. Jackson. “By working together with industry and capitalizing on our capacity for innovation, we’ve developed a clean cars program that is a win for automakers and drivers, a win for innovators and entrepreneurs, and a win for our planet.”

DOT and EPA received more than 130,000 public comments on the September 2009 proposed rules, with overwhelming support for the strong national policy. Manufacturers will be able to build a single, light-duty national fleet that satisfies all federal requirements as well as the standards of California and other states. The collaboration of federal agencies also allows for clearer rules for all automakers, instead of three standards (DOT, EPA, and a state standard).

Today’s final rules, issued by DOT’s National Highway Traffic Safety Administration (NHTSA) and EPA, establish increasingly stringent fuel economy standards under NHTSA’s Corporate Average Fuel Economy program and greenhouse gas emission standards under the Clean Air Act for 2012 through 2016 model-year vehicles.

Starting with 2012 model year vehicles, the rules together require automakers to improve fleet-wide fuel economy and reduce fleet-wide greenhouse gas emissions by approximately five percent every year. NHTSA has established fuel economy standards that strengthen each year reaching an estimated 34.1 mpg for the combined industry-wide fleet for model year 2016.

Because credits for air-conditioning improvements can be used to meet the EPA standards, but not the NHTSA standards, the EPA standards require that by the 2016 model-year, manufacturers must achieve a combined average vehicle emission level of 250 grams of carbon dioxide per mile. The EPA standard would be equivalent to 35.5 miles per gallon if all reductions came from fuel economy improvements.

Specifically, the new National Program:

Reduces carbon dioxide emissions by about 960 million metric tons over the lifetime of the vehicles regulated, equivalent to taking 50 million cars and light trucks off the road in 2030.

Conserves about 1.8 billion barrels of oil over the lifetime of the vehicles regulated.

Enables the average car buyer of a 2016 model year vehicle to enjoy a net savings of $3,000 over the lifetime of the vehicle, as upfront technology costs are offset by lower fuel costs

“We are delivering on our mission and President Obama’s call for a strong and coordinated national policy for fuel economy and greenhouse gas emission standards for motor vehicles, and we will do so in a way that does not compromise safety,” said NHTSA Administrator David Strickland.

“These are the first national standards ever to address climate change,” said EPA Assistant Administrator for Air and Radiation Gina McCarthy. “Over the coming years, America will witness an amazing leap forward in vehicle technologies, delivering fuel efficiency that will save us money and protect the environment.”

The joint final regulation achieves the goal set by President Obama to develop a National Program to establish federal standards that meet the needs of the states and the nation as a whole to conserve energy and reduce greenhouse gas emissions. President Obama first announced the effort last May with a broad coalition of automakers, the United Auto Workers, States, and the environmental community.

NHTSA and EPA expect automobile manufacturers will meet these standards by more widespread adoption of conventional technologies that are already in commercial use, such as more efficient engines, transmissions, tires, aerodynamics, and materials, as well as improvements in air conditioning systems. Although the standards can be met with conventional technologies, EPA and NHTSA also expect that some manufacturers may choose to pursue more advanced fuel-saving technologies like hybrid vehicles, clean diesel engines, plug-in hybrid electric vehicles, and electric vehicles.

In conjunction with the United States, Canada is also announcing Light Duty Vehicle GHG-Emissions regulations today. U.S. EPA and NHTSA have worked closely with Environment Canada to ensure a common North American approach.

Climate change is the single greatest long-term global environmental challenge. Cars, SUVs, minivans, and pickup trucks are responsible for almost 60 percent of all U.S. transportation-related greenhouse gas emissions.

1. Correct me if I am wrong but CO2 AND mileage limit is silly.
A gallon of gasoline when burned completely produces 19.4 pounds (8.8 kg) of CO2.

That CO2 release is unavoidable. A Prius, a Hummer, or a F150 all release 19.4 pounds of CO2 per gallon of gas burned. The CO2 reduction of a Prius comes from the fact that it simply burns less gas.

Having a mileage standard and a CO2 standard seems silly.

If you meet mileage standard you already have a CO2 standard.

30 mpg = 8.8 kg / 30 = 293 grams of CO2 per mile
35 mpg = 8.8 kg / 35 = 251 grams of CO2 per mile
40 mpg = 8.8 kg / 40 = 220 grams of CO2 per mile
45 mpg = 8.8 kg / 45 = 195 grams of CO2 per mile
50 mpg = 8.8 kg / 50 = 176 grams of CO2 per mile

Now this is with perfect combustion however the only way to produce less CO2 would be by imperfect combustion which then releases other pollutants (primarily caron monoxide).

I wonder if the CO2 cap is simply more of the dumbing down of America. It is "too hard" to explain that mpg standard is a CO2 standard and thus they plan to pass a CO2 standard also.

2. No, it's more complicated than that

... compliance level for the model year 2016 standard is projected to be 250 grams per mile, corresponding to 35.5 mpg in model year 2016, if all reductions were made through fuel economy improvements.

...

EPA is allowing auto manufacturers to earn credits toward the fleet-wide average CO2 standards for improving air conditioning systems, such as reducing both hydrofluorocarbon (HFC) refrigerant losses (i.e. system leakage) and indirect CO2 emissions related to the increased load on the engine. Earning credits for these types of greenhouse gas reductions is conditioned on demonstrated improvements in vehicle air conditioner systems, including both efficiency and refrigerant leakage improvement. Other program flexibilities, such as flex-fuel vehicle credits, temporary lead-time allowance, and advanced technology credits, will also be available to qualified auto manufacturers and are explained more fully below.

...

EPA is also setting standards to cap tailpipe nitrous oxide (N2O) and methane (CH4) emissions at 0.010 and 0.030 grams per mile, respectively. Even after adjusting for the higher relative global warming potencies of these two compounds, nitrous oxide and methane emissions represent less than one percent of overall vehicle greenhouse gas emissions from new vehicles.

3. I guess?

I just wonder how much those systems really contribute:

"hydrofluorocarbon (HFC) refrigerant losses"
How much HFC losses really occur? Enough to meaningfully affect lifecycle CO2 release?
R-134A has a high global warming potential (1300) however a car AC system has maybe 2 pounds of refrigerant. Considering a car getting 35mpg and being driven 120,000 miles will emit 65,000 pounds of CO2 any contribution from AC system would seem to be negligible.

"indirect CO2 emissions related to the increased load on the engine"
wouldn't load on engine reduce mpg rating of vehicle and thus be included in EPA mpg calculations/testing?

At least the contribution from things other than burning fuel (mpg rating) would be minor (<2%). I guess a company that is just BARELY meeting the EPA standard might not meet the CO2 limit for most passing mpg standard means they meet the CO2 standard.
