How do CBAM and CSRD interact with each other?

The Carbon Border Adjustment Mechanism (CBAM) and the Corporate Sustainability Reporting Directive (CSRD) are two key pillars of the EU’s sustainability and climate policy. Although they address different areas of environmental regulation, they are deeply interconnected and together drive companies toward greater transparency, lower emissions, and more sustainable value chains.

CBAM focuses on imported goods. It requires companies to report and pay for the embedded carbon emissions in certain imported materials. This creates a financial incentive to choose lower-carbon suppliers and pushes companies to obtain accurate emissions data from their global value chains.

CSRD, on the other hand, requires a wide range of businesses to disclose detailed sustainability information, including Scope 1, 2, and 3 emissions, climate risks, and decarbonization strategies. This expands the need for high-quality carbon data across internal operations and suppliers.

Together, CBAM and CSRD reinforce each other in several ways:

• Both require accurate, verifiable emissions data across supply chains.
• CBAM emissions values feed into CSRD Scope 3 reporting, improving transparency.
• CSRD pushes companies to track and reduce emissions, which in turn lowers CBAM-related import costs.
• Both regulations drive long-term decarbonization, encouraging businesses to adopt low-carbon suppliers, materials, and processes.

How Sustamize supports compliance with both frameworks

Sustamize helps companies align CBAM and CSRD requirements by providing integrated CO₂e data and automated calculation tools. With verified, high-resolution emission datasets and tools such as the Matcher and Assembler, sustamize enables businesses to:

• calculate product carbon footprints aligned with ISO 14067,
• generate accurate CO₂ values for CBAM declarations,
• support CSRD reporting with audit-ready data,
• streamline sustainability reporting across both regulatory domains.

By unifying data and methodology, sustamize gives companies a scalable foundation to comply with both CBAM and CSRD while improving overall sustainability performance.
