On January 1, 2026, the European Union's Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase, imposing real financial costs on imports of steel, aluminium, cement, fertilisers, electricity, and hydrogen. This landmark climate-trade policy, affecting roughly €50 billion in annual imports, now requires non-EU producers and their importers to purchase CBAM certificates tied directly to EU carbon prices. The mechanism is already driving rapid recalibration of global supply chains from China to Turkey, while triggering retaliatory trade concerns and prompting Canada, the UK, and Australia to develop their own border carbon adjustments.
What Is CBAM and How Does It Work?
The EU Carbon Border Adjustment Mechanism is a carbon tariff designed to prevent carbon leakage—the phenomenon where EU manufacturers relocate production to regions with weaker climate policies. By imposing a carbon price on imports equivalent to that paid by domestic producers under the EU Emissions Trading System (EU ETS), CBAM aims to level the playing field while accelerating global decarbonisation. The European Green Deal framework originally proposed CBAM as a cornerstone of the EU's 2030 climate ambition.
Under the definitive regime, EU importers of more than 50 tonnes of covered goods annually must apply for authorised CBAM declarant status. They are required to purchase CBAM certificates at a price linked to EU ETS auction rates. For the first quarter of 2026, the European Commission set the CBAM certificate price at €75.36 per tonne of CO₂ equivalent, based on the weighted average of EU ETS auction clearing prices. Importers can deduct carbon costs already paid in the country of origin, provided they can produce verified emissions data.
Supply Chains Under Pressure: Steel and Aluminium in Focus
The sectors most exposed to CBAM are iron and steel, followed by aluminium. According to industry analysis, steel importers will bear roughly 75% of total CBAM certificate costs, with annual liabilities potentially reaching €22 billion by 2035. Aluminium importers face a further 7% of costs. The mechanism creates stark competitive disparities: high-emissions hot-rolled coil from India could face costs equivalent to 80% of product value, while the same product from the US would incur only 6%.
Countries like Russia, India, Turkey, China, and Ukraine are projected to account for over 50% of certificate demand. For Chinese steel exporters, CBAM charges could reach $72–$83 per tonne by 2030 and $210–$243 per tonne by 2034 under a medium carbon price scenario. EU steel imports could decline by up to 30% by 2034, while CBAM revenue may exceed $4.1 billion annually. The EU steel safeguard measures interact with CBAM, creating a complex compliance landscape for importers.
Turkey and China: Adapting to the New Reality
Turkey, the EU's largest steel supplier outside the bloc, is particularly vulnerable. Turkish steel producers rely heavily on coal-based electric arc furnaces, resulting in higher embedded emissions. Industry groups are urging Ankara to establish a domestic carbon pricing mechanism to allow Turkish exporters to claim deductions on CBAM certificates. China, meanwhile, is exploring response strategies including cleaner production technologies, adjusted export strategies, and enhanced domestic carbon pricing. The China steel industry response to CBAM remains a critical variable in global trade dynamics.
Global Ripple Effects: Retaliation and Imitation
CBAM has sparked significant opposition from developing nations at the World Trade Organization. Countries including India, China, Brazil, and South Africa argue that the mechanism acts as a protectionist trade barrier that unfairly penalises carbon-intensive imports from nations with weaker climate regulations. Legal experts note that while the EU cites environmental protection under GATT Article XX, strict WTO conditions must be met. Critics warn CBAM could reduce GDP in export-reliant nations like Mozambique by 1.6%, worsen global inequality, and divert investment from developing economies.
At the same time, CBAM is catalysing a wave of similar policies worldwide. The UK will launch its own Carbon Border Adjustment Mechanism on January 1, 2027, covering aluminium, cement, fertiliser, hydrogen, and iron and steel. Canada is actively consulting on a domestic CBAM, with the 2024 Fall Economic Statement signalling its intention to proceed. Australia's final Carbon Leakage Review, released in February 2026, recommends a CBAM-like scheme for high-risk sectors, with cement and clinker as initial priorities. The global carbon border adjustment landscape is rapidly evolving as more jurisdictions follow the EU's lead.
Expert Perspectives on CBAM's First Year
"CBAM is the world's first carbon border tax, and its definitive phase marks a historic moment for climate policy and international trade," said a senior European Commission official. "We are closely monitoring the impacts on trade flows and industrial competitiveness, and we stand ready to adjust the mechanism if needed."
Industry analysts warn that many businesses remain unprepared. A mid-sized steel importer bringing in 10,000 tonnes annually could face €150,000–€300,000 in certificate costs, with non-compliance penalties reaching three to five times the certificate value. Without verified emissions data, default values—set 20–30% higher than actual emissions—apply, further increasing costs. A grace period for authorisation applications ran until March 31, 2026, though processing takes four to eight weeks.
FAQ: CBAM in 2026
What is the CBAM certificate price for Q1 2026?
The European Commission set the first CBAM certificate price at €75.36 per tonne of CO₂ equivalent for Q1 2026, based on the average EU ETS auction price.
Which products are covered by CBAM?
CBAM initially covers cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. The EU plans to expand coverage to all sectors under the EU ETS by 2030, and to add 180 downstream products starting in 2028.
How do importers pay for CBAM certificates?
Importers must purchase CBAM certificates through a centralised common platform. For 2026, certificate prices are calculated quarterly; from 2027, prices will be published weekly. Importers submit annual declarations and surrender the corresponding certificates by May 31 of the following year.
Can importers deduct carbon costs paid abroad?
Yes. If a carbon price has already been paid in the country of production, importers can deduct that amount from their CBAM liability, provided they can produce verified documentation.
What are the penalties for non-compliance?
Non-compliance penalties can reach three to five times the certificate value. Importers who fail to obtain authorised declarant status or submit inaccurate declarations face significant financial and legal consequences.
Conclusion: A New Era for Climate Trade Policy
CBAM's definitive phase represents a paradigm shift in global trade. By embedding carbon costs into the price of imports, the EU is forcing a fundamental recalibration of supply chains and industrial strategy. The mechanism's success will depend on its WTO compatibility, the willingness of trading partners to cooperate, and the EU's ability to support developing countries in the transition. As Canada, the UK, and Australia prepare their own border carbon adjustments, 2026 may be remembered as the year carbon pricing went global.
