After considerable waiting, the Trudeau government released on Monday draft regulations to cap greenhouse gas (GHG) emissions from Canada’s oil and gas producers.

The proposed regulations would set a cap on GHG emissions equivalent to 35 per cent of the emissions produced in 2019 and create a GHG emissions “cap and trade” system to enable oil and gas producers (who cannot reduce emissions enough to avoid the cap) to buy credits from other producers able to meet the cap. Producers unable to meet the cap will also be able to obtain emission credits (of up to 20 per cent of their needed emission reductions) by investing in decarbonization programs or by buying emission “offsets” in Canada’s carbon markets.

According to the government, the cap will “cap pollution, drive innovation, and create jobs in the oil and gas industry.” But in reality, while the cap may well cap pollution and drive some innovation, according to several recent analyses it won’t create jobs in the oil and gas industry and will in fact kill many jobs.

For example, the Conference Board of Canada think-tank estimates that the cap would reduce Canada’s GDP by up to $1 trillion between 2030 and 2040, kill up to 151,300 jobs across Canada by 2030, and national economic growth from 2023 to 2030 would slow from 15.3 per cent to 14.3 per cent.

Not surprisingly, Alberta would be hardest hit. According to the Board, from 2023 to 2030, the province’s economic growth would fall from an estimated 17.8 per cent to 13.3 per cent and employment growth would fall from 15.8 per cent to 13.6 per cent over the same period. Alberta government revenues from the sector would decline by 4.5 per cent in 2030 compared to a scenario without the cap. As a result, Alberta government revenues would be $4.5 billion lower in nominal terms in fiscal year 2030/31. And between 54,000 to 91,500 of Canada’s job losses would occur in Alberta.

Another study by Deloitte estimates that, due to the federal cap, Alberta will see 3.6 per cent less investment, almost 70,000 fewer jobs, and a 4.5 per cent decrease in the province’s economic output (i.e. GDP) by 2040. Ontario would lose more than 15,000 jobs and $2.3 billion from its economy by 2040. And Quebec would lose more than 3,000 jobs and $0.4 billion from its economy during the same period.

Overall, according to Deloitte, Canada would experience an economic loss equivalent to 1.0 per cent of GDP, translating into lower wages, the loss of nearly 113,000 jobs and a 1.3 per cent reduction in government tax revenues. (For context, Canada’s economic growth in 2023 was only 1.1 per cent.)

And what will Canadians get for all that economic pain?

In my study published last year by the Fraser Institute, I found that, even if Canada eliminated all its GHG emissions expected in 2030 due to the federal cap, the emission reduction would equal only four-tenths of one per cent of global emissions—a reduction unlikely to have any impact on the trajectory of the climate in any detectable manner or produce any related environmental, health or safety benefits.

Clearly, the Trudeau government’s new proposed emissions cap on the oil and gas sector will impose significant harms on Canada’s economy, Canadian workers and our quality of life—and hit Alberta with a wallop. And yet, as a measure intended to avert harmful climate change, it’s purely performative (like many of the government’s other GHG regulations) and will generate too little emission reductions to have any meaningful impact on the climate.

In a world of rational policy development, where the benefits of government regulations are supposed to exceed their costs, policymakers would never consider this proposed cap. The Trudeau government will submit the plan to Parliament, and if the cap becomes law, it will await some other future government to undo the damage inflicted on Canadians and their families.
