Turning Supplier Data Chaos into Carbon Clarity: Introducing Our CBAM Supplier Catalogue

Carbon is now a contract variable. Every 0.1 tCO₂/t can move per-tonne costs significantly, and from 1 January 2026, carbon cost exposure will begin shaping every deal under the EU CBAM. Yet for most importers and producers, the challenge isn’t understanding the regulation. It’s wrangling the data.

The Supplier Data Problem

CBAM compliance has created a tangle of duplicate data requests, slow responses, and inconsistent quality. Every importer is contacting the same suppliers individually. Every supplier is drowning in repetitive demands.

Forecasting exposure or benchmarking against EU intensity benchmarks takes months, not days, and still leaves gaps in confidence. The result is mispriced deals, default values, and avoidable margin risk.

Introducing the CBAM Supplier Catalogue

The CBAM Supplier Catalogue is CarbonChain’s new shared infrastructure for installation-level CBAM data. It lets installation operators and buyers manage, validate, and exchange supplier emissions data in one place, replacing manual outreach with a central workflow.

Here’s what it delivers:

• Public directory for steel and aluminium installations with searchable entity names and CN codes

• Request-to-share workflow: logged-in users can request installation data, and producers approve or decline

• Risk ratings on request: indicative carbon-intensity benchmarking without full disclosure

• Pre-filled installation profiles to reduce supplier workload

• Benchmarking views comparing intensity and implied certificate costs indexed to the EUA price

• Validated intensities for paying users with emissions data supplied directly by producers

Built on over 2,000 steel and aluminium intensity datapoints, the Catalogue provides coverage across the world’s largest steel and aluminium producers, reflecting CarbonChain’s global coverage of over 3,500+ suppliers having supported over 7.5 million tonnes of CBAM goods cleared into the EU to date.

Why This Matters (and Why Now)

From January 2026, CBAM costs begin accruing. Every tonne imported without verifiable data will default to the EU benchmark, increasing cost exposure and reducing competitiveness.

Over the past three years, CarbonChain has supported 1,750 + declarations, representing 7.5 million tonnes of goods reported into the EU. That experience revealed one truth: you can’t fix supplier data one company at a time; it requires shared infrastructure.

Built for Both Sides of the Trade

With the Catalogue importers and traders can:

• Forecast exposure, cut supplier engagement from months to days, and move to contract-ready data you can trade on

• Get instant cost insights across suppliers and commodities, aligned to the latest EUA price

• Manage all CBAM declarations in one place, from data collection to verification support

Producers and manufacturers can:

• Upload once, reach many buyers, and prepare for verification faster

• Benchmark performance against peers and defend margin in tenders

• Convert CBAM data to full Product Carbon Footprints (PCFs) in line with the GHG Protocol, ready for CBAM to PCF reporting extensions

From Compliance to Commercial Edge

CBAM compliance is just the starting line. With standardised, verifiable installation data in one system, companies can unlock:  

• Exposure forecasting and scenario analysis

• Automated verification preparation

• Benchmarking and quoting capabilities

• Integration into full-stack carbon accounting across CBAM, PCF and CCF modules

This is how compliance becomes a commercial advantage, turning carbon from a cost line into a strategic variable you can price, hedge, and manage.

A Platform Built on Experience

CarbonChain already supports around 35 per cent of steel, 40 per cent of aluminium, and 50 per cent of fertiliser imports by volume into the EU, providing the deepest coverage of any carbon accounting platform.

Our technology is proven and supports the tracking of 3.2 billion tCO₂e, with over 11 million product carbon footprints generated, and covering over 300 commodity products.

That network and expertise underpin the CBAM Supplier Catalogue, making it the most credible dataset for CBAM reporting and benchmarking available today.
