GCC Exporters and EU CBAM: How Gulf Manufacturers Should Prepare Their Carbon Data

GCC Exporters Now Face a Carbon Price at the EU Border

The EU Carbon Border Adjustment Mechanism (CBAM) entered its definitive, paying period on 1 January 2026. For GCC exporters of aluminium, steel, cement and fertiliser, that date changed the economics of selling into Europe. From now on, the carbon embedded in a tonne of Gulf metal carries a price at the EU border, and the number that sets that price is your data, not an EU estimate.

Spectreco, an ESG technology and advisory firm with offices in Atlanta, London, Lisbon, Dubai, Muscat and Lahore, works with industrial exporters and their financiers on exactly this problem: turning plant-level emissions into verified, audit-ready figures that hold up at the border. This article maps what the CBAM definitive period requires, which GCC products are most exposed, and how ISSB-aligned disclosure in the UAE, Qatar and Saudi Arabia can feed the same carbon data CBAM demands.

What the CBAM Definitive Period Requires

CBAM covers six carbon-intensive sectors: iron and steel, aluminium, cement, fertilisers, hydrogen and electricity. During the transitional phase that ran to the end of 2025, EU importers only reported embedded emissions. The definitive period attaches a cost to them.

Under the definitive regime, the obligation sits with the EU importer, now called an authorised CBAM declarant. That declarant must report the embedded emissions of each import and, from 1 February 2027, buy CBAM certificates to cover the emissions of goods brought in during 2026. The first annual CBAM declaration is due by 30 September 2027, and declarants must hold certificates equal to 50 percent of their embedded emissions through the year.

The 2025 Omnibus simplification added a single mass-based exemption. Importers bringing in 50 tonnes or less of CBAM goods per year are exempt, which removes roughly 90 percent of importers while still capturing about 99 percent of embedded emissions. For large Gulf smelters and steel mills shipping thousands of tonnes into Europe, this exemption offers no shelter. The full picture of the de minimis rule sits in our companion guide, EU CBAM 2026 Simplification: Rules for Exporters.

The cost does not stop at the current six sectors. In December 2025 the European Commission proposed extending CBAM to around 180 downstream steel and aluminium products from 1 January 2028, subject to Council and Parliament approval. Petrochemicals sit outside the list today, but the direction of travel is clear, and Gulf producers of downstream metal goods should assume the border is moving toward them.

Which GCC Products Are Most Exposed to CBAM?

Aluminium is the GCC's single largest CBAM exposure. It accounts for 99.2 percent of Bahrain's exports of in-scope goods, and between 68.1 percent and 75.3 percent of covered exports from the UAE, Oman and Saudi Arabia. Steel, cement and fertiliser make up most of the rest.

The values are material. In 2023, GCC exports of CBAM-covered goods to the EU reached the levels below, and for Bahrain those exports equalled 2.89 percent of GDP, the highest proportional exposure in the region.

The cost curve is what turns exposure into urgency. On current direct-emissions rules, the CBAM charge on GCC aluminium is modelled to climb from roughly US$4 per tonne in 2026 to nearly US$350 per tonne in 2034, an ad valorem burden rising from 0.2 percent to 12.7 percent. Producers including Emirates Global Aluminium and Aluminium Bahrain (Alba) have already committed to cutting carbon intensity by 2035, but a low-carbon smelter still loses money at the border if it cannot prove its number.

What Carbon Data Do Gulf Exporters Need for CBAM?

Gulf exporters must produce installation-level embedded emissions, measured per tonne of product in tCO2e, and get them independently verified. The EU importer reports these figures, but only the exporting installation can generate them from real production data. Without that data, the importer falls back on EU default values, and the default carries a penalty.

Source: CBAM Guide, Default Values

Default values are set above the country-specific average and rise on a schedule designed to force measurement. For steel, cement, aluminium and hydrogen, the mark-up is 10 percent above the country average in 2026, 20 percent in 2027 and 30 percent from 2028. Fertilisers carry a 1 percent mark-up. Every percentage point is a cost your competitor with verified data does not pay.

Source: CBAM Guide, Default Values

To escape defaults, the exporting installation needs three things:

• A monitoring plan built to the EU CBAM methodology, tracking direct and relevant indirect emissions at the installation level.
• Accredited verification by a third-party verifier certified under EN ISO/IEC 14065, including a physical site visit for the first period.
• A verifier report stating the specific embedded emissions figure per tonne, which the EU importer then uses in place of the default.

Source: CBAM Guide, Default Values

This is the same rigour that assurance brings to financial statements. Spreadsheet-based emissions tracking will not survive a CBAM verification visit. Producing a defensible per-tonne figure needs a controlled data pipeline from meters and production systems, which is the core of the Spectreco AI cloud-native sustainability platform.

How ISSB-Aligned GCC Disclosure Feeds CBAM Data

The work is not starting from zero. Across the Gulf, ISSB-aligned climate disclosure is now landing on the same emissions data CBAM needs, which means one measurement effort can serve two mandates.

In the UAE, Federal Decree-Law No. 11 of 2024 requires every entity to measure, report and plan to reduce its greenhouse gas emissions, with compliance due by 30 May 2026 through the MOCCAE MRV platform. The Scope 1 and Scope 2 inventory that law demands is the same inventory a smelter needs for its CBAM installation report. We cover the deadline in detail in UAE ESG Compliance: What the 30 May 2026 Deadline Means.

In Qatar, the Qatar Central Bank and the Qatar Financial Centre Regulatory Authority now mandate IFRS S1 and S2 for banks and financial institutions, effective 1 January 2026, with first reports in 2027, as set out in Qatar IFRS S1 and S2: What Banks Must Report in 2026. Saudi Arabia is moving on a voluntary-to-mandatory path under the CMA and Tadawul, reviewed in Saudi Arabia ISSB Reporting: What Tadawul Companies Must Do.

The overlap is the opportunity. An exporter that builds a verified, installation-level GHG inventory for IFRS S2 or the UAE climate law has already built most of what CBAM verification requires. Managed end to end, that single data backbone answers the regulator, the border and the financier at once, which is the model behind the Spectreco Virtual Sustainability Office.

Do GCC Exporters Pay CBAM Directly?

No. GCC exporters do not remit CBAM charges to the EU. The legal cost falls on the authorised CBAM declarant, the EU importer, who buys and surrenders the certificates. In commercial terms, that cost flows straight back to the exporter through price negotiation, contract terms and buyer selection.

An EU buyer choosing between two aluminium suppliers will favour the one with verified low emissions and complete data, because that supplier lowers the buyer certificate bill. The exporter with only default values becomes the more expensive option, even at the same mill price. CBAM is not a tax you pay. It is a competitive test your data either passes or fails.

How to Prepare Your Carbon Data for CBAM

1. Confirm your exposure. Map which of your EU-bound products fall under the six covered sectors and whether your annual volume clears the 50-tonne exemption. Most large GCC industrial exporters will be in scope.
2. Build an installation-level monitoring plan. Measure direct and relevant indirect emissions per tonne, at each production installation, using the EU CBAM methodology rather than a corporate average.
3. Line CBAM up with your ISSB and national disclosure work. Use the Scope 1 and Scope 2 inventory built for the UAE climate law, IFRS S2 or Tadawul reporting as the foundation for your CBAM figures.
4. Secure accredited verification early. Engage an EN ISO/IEC 14065 verifier ahead of importer deadlines, since the first period requires a physical site visit.
5. Give your EU buyers a data pack. Provide verified per-tonne emissions in the format importers need, and turn your carbon performance into a commercial advantage.
