2012 Honda Civic EX interior

Honda has taken it on the chin for its boring redesign of the Civic, but here's one thing it got really right: reducing the use of toxic chemicals as it manufactured the interiors. According to the Ecology Center's new report on HealthyStuff.org, the 2012 Civic uses the least amount of off-gassing plastics, materials that can lead to emissions of volatile organic compounds. VOCs have been linked to health problems, including cancer and birth defects, according to the report.

"Research shows that vehicle interiors contain a unique cocktail of hundreds of toxic chemicals that off-gas in small, confined spaces," said Jeff Gearhart, Research Director at the Ecology Center, in a statement. "Since these chemicals are not regulated, consumers have no way of knowing the dangers they face. Our testing is intended to expose those dangers and encourage manufacturers to use safer alternatives."

For example, Honda does not use bromine-based flame retardants in the Civic and specs PVC-free interior fabrics and trim, while also eliminating most heavy metals from the interior.

The worst vehicle tested, the 2011 Mitsubishi Outlander Sport, "contained bromine and antimony-based flame retardants in the seating and center console; chromium treated leather on several components; and over 400 ppm lead in seating materials," according to the report.

The good news is that PVC use is declining overall, with 17 percent of new models boasting PVC-free interiors, up from none in 2006, according to HealthyStuff.org. Some 60 percent of new vehicles do not contain bromine flame retardants. It seems like automakers are getting behind efforts to eliminate these hazardous chemicals from vehicle interiors, with HealthyStuff.org pointing out that Ford and Volvo have adopted voluntary third-party eco labels for some of their vehicles. Ford's average ratings for its vehicles showed a 30 percent improvement from the 2009/2010 study.

New Guide to Toxic Chemicals in Cars Helps Consumers Avoid "New Car Smell" As Major Source of Indoor Air Pollution
Best Picks: Honda Civic, Toyota Prius, Honda CR-Z
Worst Picks: Mitsubishi Outlander Sport, Chrysler 200, Kia Soul
Honda Rated as Top Manufacturer; PVC Reduction Efforts Hailed


(Ann Arbor, MI) - Today the Ecology Center released its fourth consumer guide to toxic chemicals in cars at HealthyStuff.org, finding the Honda Civic at the top of this year's list, and the Mitsubishi Outlander Sport at the bottom. Over 200 of the most popular 2011- and 2012-model vehicles were tested for chemicals that off-gas from parts such as the steering wheel, dashboard, armrests and seats. These chemicals contribute to "new car smell" and a variety of acute and long-term health concerns. Since the average American spends more than 1.5 hours in a car every day, toxic chemical exposure inside vehicles can be a major source of indoor air pollution.

"Research shows that vehicle interiors contain a unique cocktail of hundreds of toxic chemicals that off-gas in small, confined spaces," said Jeff Gearhart, Research Director at the Ecology Center. "Since these chemicals are not regulated, consumers have no way of knowing the dangers they face. Our testing is intended to expose those dangers and encourage manufacturers to use safer alternatives."

Chemicals of primary concern include: bromine (associated with brominated flame retardants); chlorine (indicating the presence of polyvinyl chloride, or PVC and plasticizers); lead; and heavy metals. Such chemicals have been linked to a wide range of health problems such as allergies, birth defects, impaired learning, liver toxicity, and cancer. Automobiles are particularly harsh environments for plastics, as extreme air temperatures of 192 F and dash temperatures up to 248 F can increase the concentration of Volatile Organic Compounds (VOC's) and break other chemicals down into more toxic substances.

"Automobiles function as chemical reactors, creating one of the most hazardous environments we spend time in," added Gearhart.

The good news is overall vehicle ratings are improving. The best vehicles today have eliminated hazardous flame retardants and PVC. Today, 17% of new vehicles have PVC-free interiors and 60% are produced without BFRs.

Top ranking cars in this year's release are: 1) Honda Civic 2) Toyota Prius and 3) Honda CR-Z. Worst ranking: 1) Mitsubishi Outlander Sport 2) Chrysler 200 SC and 3) Kia Soul. The Civic achieved its ranking by being free of bromine-based flame retardants in all interior components; utilizing PVC-free interior fabrics and interior trim; and having low levels of heavy metals and other metal allergens. The Mitsubishi Outlander contained bromine and antimony-based flame retardants in the seating and center console; chromium treated leather on several components; and over 400 ppm lead in seating materials.

"We're pleased to be recognized by HealthyStuff.org for our efforts. Over the past decade, Honda has taken a number of steps to reduce or remove chemicals of concern from our vehicles. We voluntarily report these efforts in our annual North American Environmental Report," stated Marcos Frommer, Manager of Corporate Affairs & Communications at American Honda.

Anyone looking to buy a new car can visit www.HealthyStuff.org and search by model, comparison shop between different models, and cross reference with fuel economy standards to find both a healthy and fuel-efficient vehicle. A widget and mobile phone application are also available. Visitors to the site are encouraged to contact car manufacturers and ask them to subscribe to voluntary third party eco labels, such as the TUV Toxproof and Oko-Tex Standard 100, and reduce their use of toxic chemicals in vehicles. A number of leading automakers, including Ford (TUV) and Volvo (Oko Tex), have already adopted these standards for some of their vehicles.

Other Findings:

Most improved automakers in terms of the average ratings for their vehicles are VW (+42%), Mitsubishi (+38%) and Ford (+30%). These represent improvement from the 2009/2010 models to the 2011/2012 models.

Two automaker had overall declining average scores from 2009/2010 to 2011/2012: Diamler AG (-29%) and Volvo (-13%).

On a fleet-wide basis PVC use is declining. Zero percent of pre-2006 vehicles had PVC-free interiors, versus 17% (34) of the 2011/2012 vehicle models which had PVC-free interiors. Flexible PVC often contains hazardous plasticizers, or "softeners," called phthalates, which off-gas during vehicle use and are deposited on dust particles and windshields, where they cause "fogging." In recent years, automakers have begun replacing PVC with polyurethanes and polyolefins, which contain fewer harmful additives and are easier to recycle.

40% of vehicle tested in 2012 contained Brominated Flame Retardants (BFRs) in the vehicle interiors. BFR's refer to a wide range of chemicals added to materials to both inhibit their ignition and slow their rate of combustion. Alternatives which provide the degree of fire safety required under law without using organic compounds of bromine exist, as well as options in product redesign.

Note: HealthyStuff.org only tests for a limited set of chemical hazards. Vehicles may also contain other chemical hazards, including chlorinated flame retardants (CFR) which were NOT tested for in this study
