No Carbon Tax? Let’s not be hasty!



                The Ontario Progressive Conservative(PC) Leadership race has again brought to front and centre the issue of a carbon tax. After the resignation of Patrick Brown as leader, all four candidates running to succeed him have come out against such a tax although the party had just (at Brown’s insistence) adopted a platform that included a carbon tax. Prior to this, Justin Trudeau’s Liberal federal government has mandated that provinces must adopt either a carbon tax or a cap-and-trade scheme. If not, the federal government will institute a carbon tax itself in those provinces in order to meet Trudeau’s commitment to fight climate change. Both British Columbia and Alberta have already implemented such a tax.  Ontario and Quebec have introduced cap-and-trade-plans that achieve the same goal. In the meantime, the U.S. government under Donald Trump has backpedaled on any climate change commitment. As a candidate, Trump had already made it clear that under no circumstances would he support a carbon tax.

               Obviously, a carbon tax (or cap-and-trade) will drive up energy prices, inevitably lead to higher consumers costs and reduce family incomes. Should we, therefore, jump on the conservative bandwagon to reject the carbon tax? Of course, the answer to this question depends on your belief about man-made climate change. Personally, I remain a skeptic about the necessity to take drastic steps to deal with climate change. I do not think the science on this issue is “settled”. However, if there is a good chance that we can reduce the predicted negative effect of climate change, Christians should favour maintaining God’s creation for our children and grandchildren. On the other hand, I think it is folly for Canada to take major action while the U.S., our most important trading partner refuses to do so. The uncertainty concerning the renewal of NAFTA and Trump’s overall protectionist attitude (e.g. tariff on steel and aluminum) are bad enough for us—considering how many Canadian jobs depend on exports to the U.S.

               Nevertheless, a complete rejection of a carbon tax may be a bit hasty.  After all, as government you have to get the money somewhere. For all his left-leaning platform, Brown at least recognized that his proposed spending increases have to be offset by new revenues[1]. Those vying to succeed him have not made clear how they intend to fill the financial gap left by their rejection of the carbon tax.  Economists generally recognize that we should tax the bad rather than the good.  Instead of a tax on jobs—e.g. income tax or corporate tax, a tax on cigarettes or luxury items is preferable—as are sales taxes in general. If you believe carbon is bad, it should be taxed. A carbon tax can be revenue neutral by reducing other taxes. Reducing income taxes will even increase economic growth[2]. In effect, if you accept the need to fight climate change, then a carbon tax is, in principle, not a bad idea.[3]

A market oriented policy

               In fact, a carbon tax is entirely consistent with the preference for the market that I have been advocating on this blog.[4]  Before the carbon tax (or cap-and-trade), the most prevalent government instrument to fight climate change and to curb pollution in general--has been regulation (command-and-control); government specifies what companies and consumers can and cannot do. Regulation, however, is costly and enforcement is frequently inadequate. Past regulation has frequently been too precise or with too short a compliance deadline, so that flexibility to implement the latest, best technology is reduced. Establishment of regulations is a time-consuming process and provides opportunity for companies and bureaucrats to subvert the system. Moreover, regulations are likely to become obsolete and become the norm rather than minimum standards. Thus, continued improvement is discouraged.

               A carbon tax, on the other hand—like all “green” taxes—leaves the basic decisions to the market rather than government. It follows a very important economic principle that has been accepted , in theory, by most industrialized countries since the 1970's—that is to seek to "make the polluter pay the cost” or putting it differently, to make the user pay the “full” cost.  This principal would seem to be in accordance with the biblical concept of personal responsibility. In economic terms, that means to force the producer to "internalize" the "externalities" (or neighbourhood effects). To the extent that this can be done, the cost will be reflected in production and buying decisions--the market price will reflect the full cost in the final price. Thus, consumers will be motivated to buy less of the polluting product or scarce resource. Pollution will be reduced and/or the scarce resource will be used up more slowly. 

               Consider, for example, the production of gasoline. While the actual cost of production is reflected in the price of gasoline, various indirect costs are excluded: e.g. the cost of treating respiratory illnesses and the deaths caused by breathing polluted air, the cost of repairing acid rain damage to lakes, forests, crops and buildings caused by the emissions as well as the potential costs of oil spills and of climate change–ice melting, more destructive storms and relocation of refugees from rising sea levels.  To the extent that these costs are not currently reflected in the price of gasoline through taxes, the consumer uses more gasoline than is economically warranted. If the gasoline were to fully reflect these environmental neighbourhood effects, the price would, no doubt, increase.[5] At the higher price, consumers would use less (by reducing driving, purchasing more fuel efficient cars etc.). That is, the market's mechanism for efficiently allocating resources now "counts the cost" of pollution and climate change.  

A comprehensive, “carbon tax” on the burning of all fossil fuels reflects the full costs to society of mining coal and pumping oil, of the air pollution associated with their use and climate disruption; the increased price simultaneously reduces consumption. With a carbon tax, companies are left free to innovate and choose the most cost-effective way of reducing their carbon emissions. To save on the carbon tax, they have every incentive to do so.  Better solutions can, moreover, be adopted as soon as they become available. On the other hand, if bureaucrats have to specify the solution, those who make the decision are not the ones who pay the costs and may not possess all the relevant information. The process becomes cumbersome and time-consuming as all affected parties have to be given opportunity to provide input and comment. Once specific regulations are put in place they may stay in place for a long time. There is little incentive for governments to reopen this arduous process when new technology becomes available.  The process also reduces the motivation for companies to keep searching for better solutions. Finally, carbon taxes can be introduced gradually and increased over time so that companies’ activities are not halted abruptly and their employees thrown out of work in one fell swoop. Increases according to a predetermined schedule will permit industry to adjust. 

Pollution charges, such as the carbon tax, require government only to set the amount of the charges—the “price” of carbon. The market is then free to decide how best to reduce the pollution. Competition will motivate companies to continue to improve and keep looking for improved technology. If regulation mandates the installation of certain pollution control devices, once the requirement is implemented no further improvement in pollution abatement is likely. However, if a company is taxed on its emissions, they will be motivated to continue to seek better and lower-cost abatement methods regardless of how much they have already done in this regard. The most cost-effective alternatives are, therefore, likely to be obtained using the market (leaving companies to make choices) rather than by a regulating agency[6].

While a carbon tax can be used in conjunction with regulations, in theory at least, regulation can be significantly reduced. In practice, governments will use all the tools at its disposal including subsidies. In Ontario, for example, subsidies continue for wind turbines and solar through, among others, above-market prices paid to generators of these sources of power. However, with an escalating carbon tax, at some point, companies would decide for themselves that the cost of generating electricity using coal or natural gas (including the carbon tax) is higher than the alternatives of wind or solar. They would then switch the best alternative without the incentive of subsidies. 

Now an argument can be made that a carbon tax would hit hardest on the less wealthy. That is true, since electricity and heating are larger part of their budget than it is for those who are better off and have more discretionary spending. However, the higher prices for heat and light would also motivate them to be more stewardly with the use of these resources. Instead of, for example, providing them with a discount on their power bills, this incentive should remain. Rather, they should be compensated in a way that will not affect their decisions about power use but maintain income: e.g. refundable tax credits.

In sum, the carbon tax is a market-based solution to predicted climate change problems. If you accept the need to do something about climate change, this policy tool should not be rejected out of hand. It provides companies and consumers with the incentive to do something about it while leaving them free to choose what that action will be. Ideally, a carbon tax should be revenue-neutral by reducing other taxes. The weak in society should be compensated for the extra costs but through and income-related refundable tax credit rather than subsidies related to their use of power.
              




[2] In 2003, prominent economist N. Gregory Mankiw wrote, “Cutting income taxes while increasing gasoline taxes would lead to more rapid economic growth, less traffic congestion, safer roads, and reduced risk of global warming–all without jeopardizing long-term fiscal solvency. This may be the closest thing to a free lunch that economics has to offer.” See Lester R. Brown, Plan B: Rescuing a Planet under Stress and a Civilization in Trouble, W.W. Norton & Co. Ltd., New York, 2003. p. 232. That is all the more true when one considers another benefit to family life that may be obtained if the increased gas taxes provide incentives for employers and employees to relocate to reduce commute times. Increasing the potential for both spouses to exercise their familial  responsibilities can only be regarded favourably by Christians--see Michael Schluter and John Ashcroft, ed. Jubilee Manifesto: A framework, agenda & strategy for social reform, Inter-Varsity Press, Leicester, 2005, p.170 ,174.

[5] While it would be impossible to determine these costs exactly, that is not necessary. Rough approximations will suffice to justify setting relevant charges. In any case, some charge is better than no charge; charges can be increased over time.

[6] Of course, these advantages of a carbon tax do not take place instantaneously. It takes time for companies to invest in new methods of production and for consumers to change their buying habits.
