Auto Labels: Grades Make Consumer Sense

EPA Label Option 1

This week, U.S. EPA proposed something that could change the way consumers spend car-buying dollars—labels that make sense.

For 30 years, the federal government has required new cars and light trucks on sales lots to carry labels that show consumers the miles-per-gallon performance of that particular car or truck model. These labels have been somewhat helpful, but they don’t provide as much information as this consumer, at least, would like.

Now the agency is preparing to improve the label performance. It has unveiled two proposed approaches. Both of the new labels would tell consumers how the vehicle stacks up against others for greenhouse gas emissions and other tailpipe pollution. Both of the proposed labels also report how much it costs to fuel the vehicle each year. Only one of the labels—dubbed Label Option 1 by EPA—provides two other very important pieces of information: It also tells how much a consumer will save in fuel costs over five years, and it provides a letter grade that reflects how the vehicle performs on tailpipe emissions and efficiency.

Think about how this grading system could affect you. You could shop for a car without bringing along back issues of Consumer Reports or reams of computer printouts about auto efficiency comparisons. You could quickly scan the field and go for the A and B cars and avoid the D vehicles that spew more pollution and will cost more to fuel.  If you do happen to want a bit more information than is available on the label, EPA has taken care of that too.  Each label contains a QR code that allows many smart phones to access a web page where buyers can compare cars and personalize estimates based on their own driving habits. Department of Energy also provides some really helpful information on its fuel economy website, fueleconomy.gov.

Great idea? We think so. But the auto industry is already complaining about the grading system, trying to compare it to childhood memories of failing or passing.

EPA Label Option 2

We think of this system as being more comparable to the grading system health departments have used for restaurants for years. You’ve probably noticed the placards. They protect diners from unhealthy food preparation practices and encourage high performing restaurateurs to keep up the good work.

Grades mean something. They’re easy to read and understand. They can steer you quickly toward a smarter car purchase. They are, in short, consumer friendly.

Some states already require cars and light trucks to carry information about pollution levels on their sales labels. EPA’s proposal significantly improves on that model.

You have a chance to weigh in on all of this. EPA is inviting everyone—not just policy wonks and auto industry representatives—to voice an opinion about the labels. The agency needs to hear from consumers who care about good value and a clean environment. The agency will be taking comments for 60 days, which means you need to submit your thoughts by the end of October.

The final version of the new label will be adopted by the end of the year, and the new label will appear on new cars and light trucks beginning in the 2012 model year.

Opportunity: Reduce emissions of the overlooked accomplices of CO2

The global warming culprit we hear the most about is carbon dioxide (CO2), but human activity produces a host of other, shorter-lived pollutants that act as “partners in crime” in contributing to climate change.

Until recently, most of the attention paid to these pollutants has centered around their detrimental effects on air quality and human health – the pollutants include fine particles such as black carbon and gases that form smog.

But because these pollutants disappear from the atmosphere relatively quickly, they also give us an important opportunity to put the brakes on the rapid rise in global temperature. If people around the world can reduce the amounts that they emit, everyone will see an immediate benefit and help avoid dangerous tipping points in the climate system over the next few decades.

My colleagues Nadine Unger and Drew Shindell at the NASA Goddard Institute for Space Studies (GISS) and I just published a paper in the journal Atmospheric Environment that offers additional insight into the climatic role of these pollutants. Our findings come at a time when activity on domestic and international climate policy in general and on black carbon policy in particular is ramping up.

For this paper, we delved into emissions from two key sectors, transportation and power generation, for the U.S. and the world. We primarily used a global climate model developed at NASA GISS that simulates the transport of pollutants by wind and the chemical and physical reactions that transform the pollutants into smog and particles. The model also calculates the warming or cooling effect of the different pollutants.

One of our important findings is that transportation is a particularly good sector to target quickly for emissions controls because it produces a lot of black carbon (think: diesel exhaust) and ozone-producing gases, in addition to CO2. In contrast, emissions cuts in the power generation sector do not offer the same short-term opportunity. That sector emits little black carbon, but it does create much sulfate particle pollution. Sulfate particles are bad for air quality and acid rain, but in the short term actually counteract the warming effects of CO2 emissions. Of course, it is essential to clean up the power sector to address long-term climate damage from CO2, as well as health problems from sulfate particles, ozone smog and other pollutants. But short-term opportunities to slow global warming are more significant in the transportation sector.

We also considered a hypothetical example of switching the transportation sector to a zero-emissions or electric power source, such as in plug-in hybrid electric or pure electric technologies.The result: A hefty benefit for the climate.

The switch to a zero-emissions or electric power source would decrease the warming effect if you just consider CO2 emissions.  (Though increased CO2 emissions from the electricity generation sector would offset the decrease in direct emissions from vehicles to a certain extent.)

But reducing the non-CO2 pollutants provides even more benefit for the climate. Zero-emission or electric transportation would greatly reduce black carbon emissions.  The short-term benefits to be gained from focus on the transportation sector are important for policymakers to note.

Last week’s announcement by President Obama on national greenhouse gas emissions standards for passenger cars and light trucks is a significant step in this direction. Further action is needed to clean up the exhaust from existing heavy-duty trucks and other diesel-powered transport, both in this country and internationally.

Unger and her colleagues are working to expand the published analysis to include a full suite of economic sectors, including industry, non-road transport and agriculture, and additional greenhouse gases such as methane and nitrous oxide.

Look for another paper in the near future.

White House Fax Flippant on Grim Impacts of Global Warming

Vickie Patton's profileTomorrow, the U.S. Senate Environment and Public Works Committee will hold an important hearing on the regulation of greenhouse gas emissions under the Clean Air Act. On April 2, 2007, the U.S. Supreme Court affirmed the power of the U.S. Environmental Protection Agency (EPA) to address global warming under existing law. Unfortunately, EPA’s progress has been stymied by stiff winds blowing from the White House.

Environmental Defense Fund has uncovered a document that provides a disturbing look at the White House’s views on global warming science, views that were revealed as part of White House efforts to interfere with progress at EPA. On June 20, the White House Office of Management and Budget transmitted a fax to EPA with numerous comments on a critically important EPA technical document examining how global warming endangers human health and the environment.

The summary below highlights a few remarkable examples from the White House fax [PDF].

Redefining Green for Corporate Fleets

Jason Mather's profileNearly 7 million passenger vehicles on the road today are in commercial operations. These vehicles are driven hard, averaging nearly double the mileage, fuel consumption and emissions of personal vehicles. As a result, fleets are not only expensive to operate, but are also a major source of global warming pollution.

Environmental Defense Fund has been working with some of the largest commercial fleets – including Fortune 500 titans Abbott, DuPont and Owens Corning – to identify ways to reduce fuel consumption, costs, and greenhouse gas emissions. Our efforts have delivered results. Fleets that fully implemented the program outlined below reduced their emissions by an average of 14 percent, and reduced lifecycle operating costs by 4 percent.
