Hybrid Cars not cutting it

Hybrid Vehicles Failing to Produce Environmental Benefits

Despite government rebates for hybrids offered to consumers in U.S. and Canada, the programs are failing to produce environmental benefits, yet the programs continue to cost consumers. This according to a new study, “Green Drivers or Free Riders? An Analysis of Tax Rebates for Hybrid Vehicles,” from the University of British Columbia (UBC).

The study finds that hybrid sales have not replaced gas guzzling SUVS, but rather have replaced small, relatively fuel-efficient, conventional cars. Too bad considering SUVS, trucks and vans produce substantially greater carbon emissions.

Amarish Chandra, a professor at UBC’s Sauder School of Business and co-author of the study said, “If the intention of rebate programs is to replace gas guzzlers with hybrids, they are failing.”

He goes on to say that large vehicle sales have risen steadily since the introduction of hybrid rebates. The study also finds that the majority of consumers who purchase hybrids were not motivated to do so by government 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.”

Hybrid rebate programs are currently offered by the governments of the U.S. and 13 states, including Washington, Oregon, Illinois and Colorado, and five Canadian provinces, including B.C., Ontario, Quebec, PEI and Manitoba. The Canadian government offered hybrid rebates during 2007-2008.

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

“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. In the U.S. hybrid rebates can range from $900 up to $3,400 but some models no longer qualify, such as the Toyota and Honda hybrids. Apparently, the inefficiency of rebate programs rises disproportionately when governments increase rebate levels.

The study finds that Canadian provinces that offer rebates have spent an average of $195 per tonne of carbon saved or, equivalently, $0.43 for every litre of gasoline that a vehicle consumes over its 15 year average life expectancy.

But this isn’t enough. Chandra claims that governments could garner greater environmental benefits by purchasing carbon offsets (currently priced between $3 and $40 per tonne on carbon markets) or investing in green jobs and technologies. However, carbon offsets are a murky area, and the U.S. government has currently passed a cap and trade policy which I fondly call “crap and raid”.

While hybrid rebates help governments to appear environmentally progressive, Chandra suggests that some programs may serve as de facto “bailouts” for the North American auto industry.

“The criteria for Ontario’s recent rebate increase seem designed to benefit domestic manufacturers, especially General Motors,” Chandra says. “The biggest rebates will be given to purchasers of the Chevy Volt, rather than other hybrids like the Toyota Prius.”

In addition to Chandra, the other 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. Researchers used Canadian vehicle sales data over a 17-year period from 1989 to 2006. Results are believed to extend to the U.S. market, given the similarities between auto industries, in terms of vehicle buying patterns, pricing structures and car models.
