Globally, from China and Germany to the United States, electric vehicle (EV) subsidies have been championed as an effective strategy to boost production of renewable technology and reduce greenhouse gas emissions (GHG).

But a new study by Concordia economics professor Ian Irvine shows that subsidizing EVs in the North American context will not reduce GHG emissions in the short-term, and may even increase them — at a cost to taxpayers.

Recently published in Canadian Public Policy, Irvine’s study compared the incentives for producing EVs that are found in the Corporate Average Fuel Economy (CAFE) standards, North America’s fuel-efficiency regulations, with new EV subsidy policies in Ontario, Quebec and British Columbia.

He found that, while the subsidies encourage the production of more EVs, they undermine the efficiency requirements of existing incentives for conventional vehicles. This results in a zero or negative near-term GHG benefit.

“Sometimes you have more than one policy aimed at a particular goal, and usually those policies are complementary,” Irvine notes. “But in this case, they work at cross purposes.”

In 2012, CAFE was amended to require manufacturers to continuously reduce the average carbon dioxide (CO2) emissions of their fleets by five per cent a year between 2017 and 2025.

Typically, the amount of CO2 each vehicle is allowed to emit is related to its footprint, defined as the area between its wheels. However, Irvine says, because the annual GHG reduction targets are organized on an average fleet-wide basis, manufacturers are allowed some flexibility in how they distribute the annual efficiency improvements within and across different vehicle categories.

‘This is what we call a regressive policy’

Under CAFE’s rules, an electric car is considered to have a zero emissions footprint. As an incentive designed to stimulate investment in EVs, a manufacturer that produces an EV is given a carbon credit that can be sold to another manufacturer, applied to a future year or applied to other vehicles in the manufacturer’s fleet.

As a further incentive, the manufacturer is granted a bonus carbon credit over and above the equivalent of CO2 that the sale of the EV removes from the atmosphere. For EVs, this bonus credit, or multiplier, started at 2.5 in 2016 and declines to 1.5 in 2025.

As Irvine illustrates, if a vehicle with a footprint of 50 square feet is allowed to emit 150 grams of CO2/kilometre, then a manufacturer who sold an EV with the same footprint in 2016 is given an emission credit of 375 grams of CO2/kilometre.

“These carbon credit offsets can be used by a manufacturer to moderate the GHG-related efficiency improvements in the more conventional vehicles that they sell,” Irvine says. “So, putting more EVs on the road with subsidies does not translate into fewer GHG emissions.”

What’s more, the subsidy policies apply to all potential buyers, not just those who wouldn’t otherwise have the means to purchase EVs. According to Irvine, this is an inefficient and wasteful use of taxpayer money.

“Research shows that subsidies for vehicle purchases typically benefit the top ten percentile of income distribution,” says Irvine. “This is what we call a regressive policy.”

All told, Irvine sees the prime lesson of his study to be caution.

“In developing these types of policies, we need to look before we leap,” he says. “In Ontario, we’re giving grants of up to $14,000 to EV purchases. That’s a lot of taxpayer money. And if people think it’s going toward reducing GHG emissions, we should confront that misunderstanding.”

  1. The author unfortunately supports the common attitude that “what is your money is my money” only too often expressed by the left. Specifically he indicates that the tax incentives are a bad use of tax payer money. For more expensive cars such as the Tesla, the so-called tax incentive is really nothing more than a partial rebate of taxes that would be paid by the buyer of the vehicle. It is not “taxpayer money” but rather money owned by the buyer. Given the cost of the battery and the public benefit from charging at night and using up surplus “off-peak power” (another benefit that is not factored into the analysis), I don’t think that an incentive to the buyer is unreasonable. The issue rather is with the way the car companies have been able to lobby to create a regulatory environment where such a perverse situation can happen (use of EVs increases CO2 emissions!). Sorry author – very interesting perspective – but the prescription is completely wrong! Rather than criticizing the EV and the incentives to buy EVs, the article should explain that this is really a temporary incentive (both incents the buyers and the producers of the cars) to promote EVs.
