Safety, comfort trump environment when Americans pick cars

Of course their study, conducted in Sacramento among environmentally-conscious citizens, seems to overlook the 3 million hybrids the Toyota Motor Corporation has sold over the last ten years – not to mention similarly “green” vehicles sold by other OEMs.

Nevertheless, An Investigation into Constraints to Sustainable Vehicle Ownership: A Focus Group Study sought to answer three questions: To what extent do people believe their vehicle reflects their environmental attitude? What keeps people from aligning their attitudes with their vehicle choices? Finally, what changes would permit them to bring their vehicle more closely in line with their attitudes on sustainability?

"Though most Americans hold pro-environmental attitudes, their behavior toward vehicle ownership doesn't always reflect that," said Dr. Flamm. "Significant constraints appear to prevent them from buying smaller, more fuel-efficient, less-polluting vehicles. But researchers have only a simplistic understanding of what those constraints are and how individuals describe and react to them."

This study explored these limitations psychologists refer to as an "attitudes-behavior gap" in depth through a series of focus group discussions with 36 residents of the Sacramento, Calif., metropolitan region with pro-environmental attitudes.

We take issue with Dr. Flamm’s assertion that “most” Americans are pro-environment and think this reflects a distinctly West Coast attitude. Folks in the heartland are not necessarily so sold on sustainability.

The academic analysis of the study reportedly revealed the vehicles currently on the market, family and work responsibilities, residential choices, personal routines and preferences all limited vehicle choices to ones poorly reflecting their pro-environmental stance. The discussions revealed serious misunderstandings about the environmental impacts of owning and using vehicles, making it difficult to accurately assess the sustainability of different choices.

The key conclusions were that pro-environmental concerns rarely became important when people bought a new or used vehicle. Many people perceived significant downsides to buying fuel efficient, low emissions vehicles and there’s mixed evidence on the potential for green attitudes to significantly influence patterns of vehicle purchase and use. For some the relationship between automobiles and the environment was unlikely to be a priority because other factors took precedence, such as safety, comfort, and reliability.

Nevertheless, the study suggests providing more accurate information to buyers about the environmental impacts of vehicles during the purchasing process could influence some choices and could be a useful strategy in linking environmental attitudes and vehicle choices more closely.

Manufacturer efforts to design and market vehicles with the features and functionality consumers want while using less energy and polluting less are important to making the purchase of sustainable vehicles easier. Policy-makers can help to facilitate this by making it cheaper and more convenient for vehicle buyers to own vehicles with smaller environmental impacts.

Further research is needed to test whether the results from this qualitative research project hold true for larger populations. The complete report is available for free download from the Mineta Transportation Institute.
