After two years of deliberations, the Trudeau government (specifically, the Environment and Climate Change Canada department) has unveiled the final version of Ottawa’s plan to slash greenhouse gas emissions (GHGs) from the oil and gas sector.

The draft regulations, which still must pass the House and Senate to become law, stipulate that oil and gas producers must reduce emissions by 35 per cent from 2019 levels by between 2030 and 2032. They also would establish a “cap and trade” regulatory regime for the sector. Under this system, each oil and gas facility is allocated a set number of allowances, with each allowance permitting a specific amount of annual carbon emissions. These allowances will decrease over time in line with the government’s emission targets.

If oil and gas producers exceed their allowances, they can purchase additional ones from other companies with allowances to spare. Alternatively, they could contribute to a “decarbonization” fund or, in certain cases, use “offset credits” to cover a small portion of their emissions. While cutting production is not required, lower oil and gas production volumes will be an indirect outcome if the cost of purchasing allowances or other compliance options becomes too high, making it more economical for companies to reduce production to stay within their emissions limits.

The oil and gas industry accounts for almost 31 per cent of Canada’s GHG emissions, while transportation and buildings contribute 22 and 13 per cent, respectively. However, the proposed cap applies exclusively to the oil and gas sector, exempting the remaining 69 per cent of the country’s GHG emissions. Targeting a single industry in this way is at odds with the policy approach recommended by economists including those who favour strong action to address climate change.

The oil and gas cap also undermines the Trudeau government’s repeated claims that carbon-pricing is the main lever policymakers are using to reduce GHG emissions. In its 2023 budget (page 71), the government said “Canada has taken a market-driven approach to emissions reduction. Our world-leading carbon pollution pricing system… is highly effective because it provides a clear economic signal to businesses and allows them the flexibility to find the most cost-effective way to lower their emissions.”

This assertion is vitiated by the expanding array of other measures Ottawa has adopted to reduce emissions—hefty incentives and subsidies, product standards, new regulations and mandates, toughened energy efficiency requirements, and (in the case of oil and gas) limits on emissions. Most of these non-market measures come with a significantly higher “marginal abatement cost”—that is, the additional cost to the economy of reducing emissions by one tonne—compared to the carbon price legislated by the Trudeau government.

And there are other serious problems with the proposed oil and gas emissions gap. For one, emissions have the same impact on the climate regardless of the source; there’s no compelling reason to target a single sector. As a group of Canadian economists wrote back in 2023, climate policies targeting specific industries (or regions) are likely to reduce emissions at a much higher overall cost per tonne of avoided emissions.

Second, forcing down Canadian oil and gas emissions within a short time span (five to seven years) is sure to exact a heavy economic price, especially when Canada is projected to experience a long period of weak growth in inflation-adjusted incomes and GDP per person, according to the OECD and other forecasting agencies. The cap stacks an extra regulatory cost on top of the existing carbon price charged to oil and gas producers. The cap also promises to foster complicated interactions with provincial regulatory and carbon-pricing regimes that apply to the oil and gas sector, notably Alberta’s industrial carbon-pricing system.

The Conference Board of Canada think-tank, the consulting firm Deloitte, and a study published by our organization (the Fraser Institute) have estimated the aggregate cost of the federal government’s emissions cap. All these projections reasonably assume that Canadian oil and gas producers will scale back production to meet the cap. Such production cuts will translate into many tens of billions of lost economic output, fewer high-paying jobs across the energy supply chain and in the broader Canadian economy, and a significant drop in government revenues.

Finally, it’s striking that the Trudeau government’s oil and gas emissions cap takes direct aim at what ranks as Canada’s number one export industry, which provides up to one-quarter of the country’s total exports. We can’t think of another advanced economy that has taken such a punitive stance toward its leading export sector.

In short, the Trudeau government’s proposed cap on GHG emissions from the oil and gas industry lacks any solid scientific, economic or policy rationale. And it will add yet more costs and complexity to Canada’s already shambolic, high-cost and ever-growing suite of climate policies. The cap should be scrapped, forthwith.
