The World's First Carbon Tariff Is Live

On January 1, 2026, the EU activated the definitive phase of the Carbon Border Adjustment Mechanism. For exporters across Latin America, MENA, South Asia, and Africa, CBAM is rewriting the economics of international trade in carbon-intensive goods.

After three years of transitional reporting, EU importers of steel, aluminium, cement, fertilisers, hydrogen, and electricity now face financial obligations: they must purchase CBAM certificates for the embedded carbon emissions in every qualifying shipment.

The mechanism is designed to level the playing field between EU producers — who already pay for carbon under the EU Emissions Trading System — and foreign competitors who don't face equivalent carbon costs. But its impact extends far beyond Europe's borders.

Who's Actually Affected — And How Much

CBAM currently covers six sectors: iron and steel, aluminium, cement, fertilisers, electricity, and hydrogen. The EU has proposed adding 180 downstream products with high steel or aluminium content. By 2030, all sectors covered by the EU ETS will be included.

The countries most exposed are those that export large volumes of CBAM goods to the EU with high carbon intensity and no domestic carbon pricing to offset the tariff.

The Default Value Trap

Exporters who cannot provide verified, product-specific emissions data face a compounding penalty. The EU applies country- and product-specific default emission values — already conservatively high — plus a markup: 10% in 2026, 20% in 2027, and 30% from 2028 onward.

Latin America: The Most Exposed Region You're Not Talking About

While much of the CBAM discussion has focused on Turkey, India, and China, Latin America's exposure deserves closer attention — particularly because most LATAM countries lack domestic carbon pricing mechanisms, meaning zero deductions from CBAM certificates.

Brazil stands out as the most affected country in the region. With nearly €2 billion in iron and steel exports to the EU and a carbon cost intensity 3.4 times the EU average for steel and 8 times for aluminium, the financial exposure is substantial. Colombia (trade exposure index of 0.748 for steel) and Venezuela (50% of steel exports and 35% of aluminium exports directed at the EU) face similar challenges.

Trinidad and Tobago presents a unique case: its fertiliser carbon cost intensity of 108% — more than double the EU average of 52% — gives it the highest economic exposure index globally at 2% of GDP.

But there's a counterpoint. Brazil's cement sector actually produces below EU carbon intensity averages, and countries like Mexico and Colombia have low-carbon aluminium production that could gain competitive advantage over dirtier producers in Asia and Africa.

MENA: Risk and Opportunity in Equal Measure

MENA's CBAM exposure is concentrated in aluminium, steel, fertilisers, and — increasingly — hydrogen. No major MENA economy currently operates an emissions trading system comparable to the EU ETS, which means full CBAM liability on exports.

However, producers using electric arc furnace technology — like Emirates Steel in the UAE — have carbon intensities well below global averages. As EU importers start factoring CBAM costs into procurement decisions, lower-carbon MENA producers could actually gain market share from coal-dependent competitors in India and China.

The hydrogen angle adds another dimension. As the EU's CBAM already covers hydrogen, MENA countries with green and blue hydrogen ambitions — Saudi Arabia's NEOM project, the UAE's H2 strategy, Oman's green hydrogen plans — need to ensure their production meets EU emissions thresholds to avoid CBAM costs on what is meant to be a clean fuel export.

Beyond CBAM: The EUDR Double Hit for Latin America

For Latin American exporters, CBAM is only the first wave. The EU Deforestation Regulation, taking effect December 30, 2026, for large companies and June 30, 2027, for SMEs, requires that seven commodities — soy, cattle, coffee, cocoa, wood, rubber, and palm oil — are proven deforestation-free with geolocated traceability data before entering the EU market.

Brazil is the epicentre. Exports of EUDR-covered products reached an estimated $17.5 billion in 2022. The EU is the primary destination for Brazilian coffee, the second-largest for soy and palm oil, and the third-largest for cattle and wood products.

For LATAM producers, the combined effect of CBAM (industrial commodities) and EUDR (agricultural commodities) means that EU market access across virtually all major export categories now requires sustainability data infrastructure. Companies that invest in this infrastructure now will have a competitive moat. Those that don't risk losing their most valuable export market.

The Playbook: Four Steps for Exporters

1. Calculate your actual embedded emissions. Default values are designed to be punitive. A 10% reduction in actual emissions can reduce CBAM certificate costs by up to 30% for steel. The ROI on accurate measurement is immediate.

2. Get third-party verification. From 2026, verified data is required for CBAM cost optimisation. From 2028, the markup on default values reaches 30%. Verification is no longer optional — it's the difference between competitive pricing and being priced out.

3. Build a decarbonisation roadmap. CBAM certificates will increase every year as free EU ETS allowances phase out until 2034. The companies investing in emissions reduction now will face lower marginal costs as the tariff escalates.

4. Turn compliance into competitive advantage. CBAM is creating the first global marketplace for low-carbon industrial materials. EU buyers will increasingly preference verified low-carbon suppliers. Position your products accordingly.

The Bigger Picture

CBAM is not an isolated European regulation. The UK will implement its own carbon border adjustment by 2027. Countries including Brazil, Indonesia, Taiwan, Vietnam, Malaysia, and Serbia are introducing domestic carbon pricing partly in response to CBAM. China is expanding its ETS to cover most major emitting sectors by 2027.

The direction of travel is clear: carbon costs are being embedded into international trade architecture. The question for exporters in Latin America, MENA, and the Global South is not whether to prepare, but how fast they can build the measurement, verification, and reduction infrastructure that EU market access now demands.
