In British Columbia – A Carbon Tax that Works Just Fine

July 25, 2013


A new report has come out updating and summarizing British Columbia’s experience with a modest Carbon Tax.

Sustainable Prosperity:


• Since the carbon tax took effect (July 1, 2008), BC’s fuel consumption has fallen by 17.4% per capita (and fallen by 18.8% relative to the rest of Canada).
• These reductions have occurred across all the fuel types covered by the tax (not just vehicle fuel)
• BC’s GDP kept pace with the rest of Canada’s over that time
• The tax shift has enabled BC to have Canada’s lowest income tax rates (as of 2012).
• The tax shift has benefited taxpayers; cuts to income and other taxes have exceeded carbon tax revenues by $500 million from 2008-12.
Stewart Elgie, Professor of law and economics at University of Ottawa, and the report’s lead author, said:

“BC’s experience shows that it is possible to have both a healthier environment and a strong economy — by taxing pollution and lowering income taxes.”

Canada’s premiers meet from July 24-26 to discuss a proposed Canadian Energy Strategy which includes “a more integrated approach to climate change”. Elgie commented: “I hope that BC’s success will inspire Canada’s premiers to show leadership on a national approach to pricing carbon pollution.”

Andy Skuce in Skeptical Science:

Stewart Elgie and Jessica McClay of the University of Ottawa have a peer-reviewed articlein press in a special issue of the journal Canadian Public Policy. The article is summarized in the report BC’s Carbon Tax shift after five years: Results. An environmental (and economic) success story. The report can be downloaded here and is summarized here.
The results are similar to a previous report that I wrote about in the article BC’s revenue-neutral carbon tax experiment, four years on: It’s working, but updated, with one more year of data.  The new data show that the carbon tax is working even better than reported previously.
Fuel consumption per capita has fallen in BC by nearly 19% relative to the rest of Canada; these are just the fuels that are subject to the carbon tax. (Note that the years in these tables begin on July 1, in the previous report, they were calendar years, so the numbers do not match exactly.)
Note that all fuel use for the various types of fuel fell faster per-capita in BC than for the rest of Canada. The one exception is aviation fuel, which is mostly exempt from the carbon tax and showed no differential fall in use in BC.
Prior to the introduction of the carbon tax in BC, fuel use was already declining faster inBC than in the rest of Canada. However, once the tax was introduced the BC decline accelerated slightly. For the past two years, fuel use in the rest of Canada has risen slightly, while BC’s continues to decline.
Greenhouse gas emissions data are gathered by Environment Canada and lag one year behind the fuel use data. They show a decrease of 10% over the period of the carbon tax, much better than the -1.1% reduction for the rest of the country.
The economic data, which also only go up to 2011, show no big differences in performance between BC and the rest of Canada. The carbon tax was introduced just before the Great Recession hit in 2008 and since then BC has performed only very slightly better than the rest of the country. The significant observation here is that economic disaster has not befallen BC as a result of the carbon tax. The carbon tax is actually slightly better for taxpayers than revenue neutral. The carbon tax revenues have been fully paid back, along with an additional C$500, to individuals and businesses as income tax reductions and direct grants.

As reported previously, the tax remains popular in BC, with neither of the major provincial political parties having plans to scrap the tax and opinion polls show approximately 64% popular support for it. No doubt, part of the reason for the success is the revenue neutrality, which results in lower income taxes for most BC taxpayers than in any other province, even fossil-fuel-royalty rich Alberta. Repealing the tax would require personal and corporate income tax increases that would almost certainly be very unpopular.

“Revenue-neutral” does not mean—and could not mean—revenue neutral for every individual, it means revenue neutral for the government. People (and businesses) who create more emissions pay more carbon tax than average. The income tax rebates have been focussed on taxpayers earning less than C$117,000 per year, so gas-guzzling plutocrats would be net losers in BC .

Implications for policy makers

Roger Pielke Jr has declared, with some hyperbole, that:

The “iron law” thus presents a boundary condition on policy design that is every bit as limiting as is the second law of thermodynamics, and it holds everywhere around the world, in rich and poor countries alike. It says that even if people are willing to bear some costs to reduce emissions (and experience shows that they are), they are willing to go only so far.

BC has shown that a revenue-neutral carbon tax, set at C$30 per tonne of CO2-equivalent, can be both popular and effective. It is still unclear where Pielke’s boundary condition lies or if there is a boundary condition at all; in any case, it is clearly above $30 per tonne. The popularity of the policy is not because British Columbians, as thestereotype would have it, are all degenerate, pot-smoking lefties.

Well, we are not all lefties, anyway. In the 2011 national election, the percentage who voted for Stephen Harper’s Conservative Party was greater in BC than in Canada as a whole. The provincial government is the right-leaning BC Liberal Party that has won four elections in a row, with two of them since they introduced the carbon tax in 2008.

There are lessons from BC’s experiment that deserve to get the attention of anti-carbon-tax politicians in Ottawa, Washington, Canberra and elsewhere. Carbon taxes can work to reduce emissions without hurting the economy. And if they are designed correctly, they can even help leaders get re-elected.

    I’ve long argued the benefits of a carbon tax as being a fair way of both discouraging excessive fossil fuels use and encouraging low carbon options. To me it seems like a no brainer!

  2. MorinMoss Says:

    Wasn’t a carbon tax originally proposed by the Republicans back when they could still be called reasonably sane?
