Economists miss the point about the carbon tax revolt

From the Fraser Institute
An open letter is circulating online among my economist colleagues aiming to promote sound thinking on carbon taxes. It makes some valid points, and will probably get waved around in the House of Commons before long. But it’s conspicuously selective in its focus and unfortunately ignores the main problems with Canadian climate policy as a whole.
There’s a massive pile of boulders blocking the road to efficient policy. They have labels such as “Clean Fuel Regulations,” the oil and gas sector emissions cap, the electricity sector coal phaseout and “net-zero” requirements, strict energy efficiency rules for new and existing buildings, new performance mandates for natural gas-fired generation plants, the regulatory blockade on liquified natural gas export facilities, new motor vehicle fuel economy standards, caps on fertilizer use on farms, provincial ethanol production subsidies, electric vehicle mandates and subsidies, provincial renewable electricity mandates, grid-scale battery storage experiments, the “Green Infrastructure Fund,” carbon capture and underground storage mandates and subsidies, subsidies for electric buses and emergency vehicles in Canadian cities, new aviation and rail sector emission limits, and many more.
Not one of these occasioned a letter of protest from Canadian economists.
In front of that mountain of boulders there’s a twig labelled “overstated objections to carbon pricing” and at the sight of it hundreds of economists have rushed forward to carry it off the road. What a help.
To my well-meaning colleagues I respond that the pile of regulatory boulders long ago made the economic case for carbon pricing irrelevant. Layering a carbon tax on top of current and planned command-and-control regulations does not yield an efficient outcome, it just raises the overall cost to consumers. Which is why I can’t get excited about the carbon-pricing letter. That’s not where help with the heavy lifting is needed.
My colleagues object to exaggerated claims about the cost of carbon taxes. Fair enough. But far worse are exaggerated claims about the economic opportunities associated with the so-called “energy transition” and benefits of reducing carbon dioxide emissions. Some of the latter are traceable to poor-quality academic research, such as the continued use of the RCP8.5 emissions scenario long after it has been shown in the academic literature to be grossly exaggerated, or use of impacts estimates from climate models known to have large persistent warming biases. But a lot of it is simply groundless rhetoric. Climate activists, politicians and journalists have spent years blaming Canadians’ fossil fuel use for every bad weather event that comes along and swinging “climate emergency” declarations and other polemical cudgels to shut down rational debate. Again, none of this occasioned a cautionary letter from economists.
There’s another big issue on which the letter was silent. Suppose we did clear all the regulatory boulders along with the carbon-pricing-costs-too-much twig. How high should the carbon tax be? A few of the signatories are former students of mine so I expect they remember the formula for an optimal emissions tax in the presence of an existing tax system. If not, they can take their copy of Economic Analysis of Environmental Policy by Prof. McKitrick off the shelf, blow off the thick layer of dust and look it up. Or they can consult any of the half-dozen or so journal articles published since the 1970s that derive it. But I suspect most of the other signatories have never seen the formula and don’t even know it exists.
Because if they did, they would know that a major obstacle to emission reductions in Canada is our tax burden. The costlier a tax system, the lower the marginal value of emission reductions and the lower the optimal carbon tax rate. Based on reasonable estimates of the social cost of carbon and the marginal costs of our tax system, our carbon price is already high enough, and probably too high. I say this as one of the only Canadian economists who has published on all aspects of the question. Believing in mainstream climate science and economics does not oblige you to dismiss public complaints that the carbon tax is too costly.
Which raises my final point: the age of mass academic letter-writing has long since passed. Academia has become too politically one-sided. Universities don’t get to spend years filling their ranks with staff drawn from one side of the political spectrum then expect to be viewed as neutral arbiters of public policy issues. As such, the more signatories on letters like this the less impact it will have. People nowadays will make up their own minds, thank you very much, and a well-argued essay by an individual willing to stand alone will likely carry more weight.
Online conversations today are about rising living costs, stagnant real wages and deindustrialization. Even if carbon pricing isn’t the main cause, climate policy is playing a growing role and people can be excused for lumping it all together. The public would welcome insight from economists about how to deal with these challenges. A mass letter enthusing about carbon taxes is no substitute.

Trump confirms 35% tariff on Canada, warns more could come

Quick Hit:
President Trump on Thursday confirmed a sweeping new 35% tariff on Canadian imports starting August 1, citing Canada’s failure to curb fentanyl trafficking and retaliatory trade actions.
Key Details:
- In a letter to Canadian Prime Minister Mark Carney, Trump said the new 35% levy is in response to Canada’s “financial retaliation” and its inability to stop fentanyl from reaching the U.S.
- Trump emphasized that Canadian businesses that relocate manufacturing to the U.S. will be exempt and promised expedited approvals for such moves.
- The administration has already notified 23 countries of impending tariffs following the expiration of a 90-day negotiation window under Trump’s “Liberation Day” trade policy.
Diving Deeper:
President Trump escalated his tariff strategy on Thursday, formally announcing a 35% duty on all Canadian imports effective August 1. The move follows what Trump described as a breakdown in trade cooperation and a failure by Canada to address its role in the U.S. fentanyl crisis.
“It is a Great Honor for me to send you this letter in that it demonstrates the strength and commitment of our Trading Relationship,” Trump wrote to Prime Minister Mark Carney. He added that the tariff response comes after Canada “financially retaliated” against the U.S. rather than working to resolve the flow of fentanyl across the northern border.
Trump’s letter made clear the tariff will apply broadly, separate from any existing sector-specific levies, and included a warning that “goods transshipped to evade this higher Tariff will be subject to that higher Tariff.” The president also hinted that further retaliation from Canada could push rates even higher.
However, Trump left the door open for possible revisions. “If Canada works with me to stop the flow of Fentanyl, we will, perhaps, consider an adjustment to this letter,” he said, adding that tariffs “may be modified, upward or downward, depending on our relationship.”
Canadian companies that move operations to the U.S. would be exempt, Trump said, noting his administration “will do everything possible to get approvals quickly, professionally, and routinely — In other words, in a matter of weeks.”
The U.S. traded over $762 billion in goods with Canada in 2024, with a trade deficit of $63.3 billion, a figure Trump called a “major threat” to both the economy and national security.
Speaking with NBC News on Thursday, Trump suggested even broader tariff hikes are coming, floating the idea of a 15% or 20% blanket rate on all imports. “We’re just going to say all of the remaining countries are going to pay,” he told Meet the Press moderator Kristen Welker, adding that “the tariffs have been very well-received” and noting that the stock market had hit new highs that day.
The Canadian announcement is part of a broader global tariff rollout. In recent days, Trump has notified at least 23 countries of new levies and revealed a separate 50% tariff on copper imports.
“Not everybody has to get a letter,” Trump said when asked if other leaders would be formally notified. “You know that. We’re just setting our tariffs.”

UN’s ‘Plastics Treaty’ Sports A Junk Science Wrapper

From the Daily Caller News Foundation
By Craig Rucker
According to a study in Science Advances, over 90% of ocean plastic comes from just 10 rivers, eight of which are in Asia. The United States, by contrast, contributes less than 1%. Yet Pew treats all nations as equally responsible, promoting one-size-fits-all policies that fail to address the real source of the issue.
Just as people were beginning to breathe a sigh of relief thanks to the Trump administration’s rollback of onerous climate policies, the United Nations is set to finalize a legally binding Global Plastics Treaty by the end of the year that will impose new regulations, and, ultimately higher costs, on one of the world’s most widely used products.
Plastics – derived from petroleum – are found in everything from water bottles, tea bags, and food packaging to syringes, IV tubes, prosthetics, and underground water pipes. In justifying the goal of its treaty to regulate “the entire life cycle of plastic – from upstream production to downstream waste,” the U.N. has put a bull’s eye on plastic waste. “An estimated 18 to 20 percent of global plastic waste ends up in the ocean,” the UN says.
As delegates from over 170 countries prepare for the final round of negotiations in Geneva next month, debate is intensifying over the future of plastic production, regulation, and innovation. With proposals ranging from sweeping bans on single-use plastics to caps on virgin plastic output, policymakers are increasingly citing the 2020 Pew Charitable Trusts report, Breaking the Plastic Wave, as one of the primary justifications.
But many of the dire warnings made in this report, if scrutinized, ring as hollow as an empty PET soda bottle. Indeed, a closer look reveals Pew’s report is less a roadmap to progress than a glossy piece of junk science propaganda—built on false assumptions and misguided solutions.
Pew’s core claim is dire: without urgent global action, plastic entering the oceans will triple by 2040. But this alarmist forecast glosses over a fundamental fact—plastic pollution is not a global problem in equal measure. According to a study in Science Advances, over 90% of ocean plastic comes from just 10 rivers, eight of which are in Asia. The United States, by contrast, contributes less than 1%. Yet Pew treats all nations as equally responsible, promoting one-size-fits-all policies that fail to address the real source of the issue.
This blind spot has serious consequences. Pew’s solutions—cutting plastic production, phasing out single-use items, and implementing rigid global regulations—miss the mark entirely. Banning straws in the U.S. or taxing packaging in Europe won’t stop waste from being dumped into rivers in countries with little or no waste infrastructure. Policies targeting Western consumption don’t solve the problem—they simply shift it or, worse, stifle useful innovation.
The real tragedy isn’t plastic itself, but the mismanagement of plastic waste—and the regulatory stranglehold that blocks better solutions. In many countries, recycling is a government-run monopoly with little incentive to innovate. Meanwhile, private-sector entrepreneurs working on advanced recycling, biodegradable materials, and AI-powered sorting systems face burdensome red tape and market distortion.
Pew pays lip service to innovation but ultimately favors centralized planning and control. That’s a mistake. Time and again, it’s been technology—not top-down mandates—that has delivered environmental breakthroughs.
What the world needs is not another top-down, bureaucratic report like Pew’s, but an open dialogue among experts, entrepreneurs, and the public where new ideas can flourish. Imagine small-scale pyrolysis units that convert waste into fuel in remote villages, or decentralized recycling centers that empower informal waste collectors. These ideas are already in development—but they’re being sidelined by policymakers fixated on bans and quotas.
Worse still, efforts to demonize plastic often ignore its benefits. Plastic is lightweight, durable, and often more environmentally efficient than alternatives like glass or aluminum. The problem isn’t the material—it’s how it has been managed after its use. That’s a “systems” failure, not a material flaw.
Breaking the Plastic Wave champions a top-down, bureaucratic vision that limits choice, discourages private innovation, and rewards entrenched interests under the guise of environmentalism. Many of the groups calling for bans are also lobbying for subsidies and regulatory frameworks that benefit their own agendas—while pushing out disruptive newcomers.
With the UN expected to finalize the treaty by early 2026, nations will have to face the question of ratification. Even if the Trump White House refuses to sign the treaty – which is likely – ordinary Americans could still feel the sting of this ill-advised scheme. Manufacturers of life-saving plastic medical devices, for example, are part of a network of global suppliers. Companies located in countries that ratify the treaty will have no choice but to pass the higher costs along, and Americans will not be spared.
Ultimately, the marketplace of ideas—not the offices of policy NGOs—will deliver the solutions we need. It’s time to break the wave of junk science—not ride it.
