Hybrid vehicle rebates produce scant environmental benefits, high cost
Date:8/4/2009

Despite major costs to taxpayers in the U.S. and Canada, government programs that offer rebates to hybrid vehicle buyers are failing to produce environmental benefits, a new UBC study says.

The study finds that hybrid sales have come largely at the expense of small, relatively fuel-efficient, conventional cars, rather than large SUVs, trucks and vans, which produce substantially greater carbon emissions.

"If the intention of rebate programs is to replace gas guzzlers with hybrids, they are failing," says Ambarish Chandra, a professor at UBC's Sauder School of Business and study co-author. He says large vehicle sales have risen steadily since the introduction of hybrid rebates.

"People are choosing hybrids over similarly priced small- and medium-sized conventional cars, which are not far behind hybrids for fuel efficiency and emissions," says Chandra. "The reductions in carbon emissions are therefore not great."

The study also finds that the majority of consumers who purchase hybrids were not motivated to do so by government rebates, says Chandra, whose co-authors include Sumeet Gulati, assistant professor in UBC's Dept. of Food and Resource Economics, and Milind Kandlikar of UBC's Liu Institute for Global Issues and Institute of Asian Research.

"Our estimates indicate that two-thirds of people who buy hybrids were going to buy them anyway," says Chandra. "So for the majority, rebates are not changing behaviour they are subsidizing planned purchases."

According to the study, the inefficiency of rebate programs rises disproportionately when governments increase rebate levels. "When B.C.'s rebate jumped from $1,000 to $2,000 in 2005, the actual cost of reducing carbon emissions more than doubled," he says, noting that Ontario recently increased its rebate to a maximum of $10,000 per hybrid vehicle.

The study finds that Canadian provinces that offer rebates have spent an average of $195 per tonne of c
