Carbon pricing is market friendly but may not be fair: Don Pittis

Canadians suffering from recentbouts of extreme weather may be glad the federal government has decided to take some concrete actionto tackle climate change as soon asthis autumn.

But as the government talks seriously about a national carbon tax, there are reasons to think that it will be less-wealthy Canadians, the poor and the struggling middle-class, whofeel the effectsfrom therising cost of carbon. And if you don't believe me, look at the latest data on SUV sales.

• Justin Trudeau won't rule out imposing carbon price plan on provinces
• Truck, SUV sales aid automakers in July

The thought struck me during a holiday explorationof Richmond, B.C., bypublic transport. Looking down from the SkyTrain window I noticed a Volvo car lot packedwith SUVs ready for sale.

Carbon effect

"Why is it that in the province with the carbon tax that economists like best, where people are generally environmentally inclined, carbon-spewing SUVsare still such a hot seller?" I asked myself.

The answer may be that while carbon taxes have a real effect onconsumerbehaviour, the effect on people who can afford oneis just not significant enough to overcome their desire for a new SUV.

Internalizing externalities

For instance, mostVancouverites whobought their houses 10 years or more ago, will behardly affected by the additional cost ofcarbon tax. The people forced to change their ways will bethose who, due to low income, or high housing costs, need to count their nickels.

There is a good reasoneconomists preferto fight climate change with"taxes that reflect environmental externalities," such as a carbon tax, according toa report from the think-tank Canada2020.

It's the same reason why the much-vaunted powers of market forces don't step in to counterthe economic damage climate change is doing to the world.

The problem is the disconnect between businesses that profit from producing carbon and the economic impact on those who are suffering from its effects.

Here in Canada we can watch our oil stocks rise,crank up the air-con and stay indoorswhile, for example,farms in the Middle East, which is suffering a 14-year drought, turnto dust. We know there is a cost to burning fossil fuels, but economists would say the damage is"external" to the calculations of profit and loss for thebusinesses producing the carbon the oil companies and their shareholders.

Nasty, and costly, surprises

The purpose of a carbon tax is to bring those external costs, whether drought, loss of land to coastal flooding,disrupted Canadian weather patterns, or other nasty surprises, back into the business calculus of carbon-producing companies.

• Climate change could expose Cold War-era Arctic military base
• Russian anthrax outbreak linked to climate change
• As peatlands dry out from climate change, wildfire risk increases

The great thing about a carbon tax, instead ofa government-imposed rule about exactly how much carbon a business should produce, is that businesses can weigh the cost of cutting carbon against other costs and make the most business-efficient choice about how and where to cut costs.

Will it wreck the economy?

Economists like that idea.

"Even with a $120 per tonne carbon price (a figure way beyond what any jurisdiction is currently considering), 90 per cent of Canada's economy would still be virtually unaffected by competitiveness challenges," wroteMcGill economist Chris Ragan, head of the Ecofiscal Commission, a privately sponsored group promoting fighting climate change without wrecking the economy.

All verywell for businesses. But in an economy where there is an increasing gulf between richer and poorer,market pricing can have a different effect.

For example, a standardcomplaint about road pricing for high-speed laneson public highwaysisthat people wealthy enough to pay the extra charge get to travel fast in their fancy cars while the poor schmuckin hisrusty Civic is mired in traffic. It is like endlesslywalking past the first-class passengers while heading for your cramped seatin the back.

Voluntary climate tax

Even in places like Vancouver, where gasoline sells for anything up to $1.20 a litre,carbon pricing hasnot been enough to interrupt the North American twin love affairs with gasoline and the SUV.

In fact, so far, it is prestige and not marketpricing that has driven the move to electric vehicles such asTesla and the newly revealed Karma Revelo. In that way, wealthier Canadians are paying a completely voluntary tax to move the economy intoa low-carbon regime.

• Thanks to Tesla, electric car in passing lane to the future
• Climate change resistance is futile so build all the pipelines

While I do not plan to sellmy house andbuy a $200,000 Tesla Model X, I will smile and wave at the driver of the first ones I seein ordinary traffic. Theywill be a rich earlyadopters using their own money to subsidize the transition to a lower carbon economy.
