EU Carbon Tariffs: Canada Loses Exemption Despite Domestic Pricing

Canada’s national carbon pricing system will not shield domestic metal exporters from a new European Union border charge.

Internal documents obtained through an access to information request confirm that Canadian iron, steel, and aluminum products are not exempt from the Carbon Border Adjustment Mechanism. This determination holds despite a decade-old trade agreement between the two partners.

A memo from Global Affairs Canada signed on December 10, 2025, defines the mechanism as a border charge or effectively a carbon tariff. The government estimates that $2.8 billion worth of goods annually are exposed to this levy. The exposure falls primarily on metals that already face pressure from United States tariffs.

The timeline for implementation is clear. The EU is currently applying the mechanism at a low level. It will ramp up to full implementation by 2034. Canadian exporters face additional compliance costs and a carbon charge at the border beginning in 2027. European importers will be responsible for paying this charge.

Ottawa officials are working to mitigate these costs during the Canada-EU Summit held in Montreal this week. Prime Minister Mark Carney stated on Tuesday that the summit marks the start of negotiations for closer strategic partnership with the 27-member bloc. Environment and Climate Change Minister Julie Dabrusin is attending the summit. Her office noted that Canada is advocating for recognition of its industrial carbon pricing systems and streamlined administrative processes.

In an interview on October 22, Dabrusin did not specify whether negotiators were making progress. She said her goal is to ensure an effective industrial carbon pricing system that supports industry competitiveness and Canadian jobs. European Union officials told reporters that both sides are committed to tackling climate change and are working to align baselines and processes.

The internal note flags risks associated with implementing the tariff as Canada seeks to diversify trade away from the United States. While the overall exposure appears modest, the impact varies by region. Newfoundland and Labrador faces the steepest financial hit. The briefing note states that an annual average of $885 million in iron and steel exports from the Atlantic province are exposed to the tariff. This amount represents almost half of the province's exports in that sector.

Quebec also faces substantial exposure. The value of aluminum, iron, and steel exports exposed in the province amounts to about $792 million annually. These figures are averages based on data from 2021 to 2024. Exposure could increase as Canadian goods seek new buyers to avoid U.S. tariffs. The documents state that an exemption for Canada is not currently possible because the Canadian carbon price is not linked to the European Union Emissions Trading System. Countries like Switzerland, Norway, Iceland, and soon the United Kingdom are exempt because their systems are linked to the European market.

Climate trade experts warn that the mechanism represents a major shift in how trade is treated. Ross-Linden Fraser, acting director at the Canadian Climate Institute, described it as a big change. Aaron Cosbey, an economist at the International Institute for Sustainable Development, noted that exporters are already incurring costs to measure emissions and have figures reviewed by accredited verifiers. He called this a costly prospect. Cosbey estimates that by 2034, Canadian steel could cost an additional $150 per tonne due to the tariff. This amount is more than 10 percent of the open market price for a tonne of steel.

The EU carbon price in 2025 is approximately $134 per tonne, compared to $95 per tonne in Canada. The Carney government’s recent energy accord with Alberta weakened the national carbon price further. While countries with carbon prices will receive credit, it is unclear how the EU will recognize Canada's. Major producers Rio Tinto and ArcelorMittal declined to comment. Canada Nickel CEO Mark Selby said his company is well positioned to export low-carbon steel to Europe. He estimated the long-run cost would be minimal, describing it as pennies per tonne.
