For manufacturers selling across borders, a verified carbon footprint is no longer optional. European and global buyers now ask for greenhouse gas (GHG) data as a condition of supply, and the EU Carbon Border Adjustment Mechanism (CBAM) makes verified embedded emissions a legal requirement from 2026. This guide explains what export manufacturers need to know and do.
Why Exporters Need a Verified Carbon Footprint
International customers use carbon data to manage their own Scope 3 value-chain emissions under the GHG Protocol. A verified footprint under ISO 14064-1 (organization) or ISO 14067 (product) shows that your numbers are credible, comparable and independently checked. It also protects market access as regulations tighten.
EU CBAM: What Exporters Must Know
CBAM, established by Regulation (EU) 2023/956, entered its definitive period on 1 January 2026, replacing the transitional phase that ran from 2023 to 2025. It applies to six sectors: cement, aluminium, fertilisers, iron and steel, hydrogen and electricity. EU importers require CBAM authorization, and installations exporting more than 50 tonnes per year of relevant goods face reporting and financial obligations. The core input is verified embedded emissions data for each product.
ISO 14064 and ISO 14067 for Exporters
Build your export readiness on two standards. ISO 14064-1:2018 quantifies and reports organizational GHG emissions across Scope 1, 2 and 3. ISO 14067:2018 quantifies the product carbon footprint of a specific good in CO2e over its life cycle; offsetting is not allowed in the quantification. Both are verified by an accredited body under ISO 14064-3, which is what CBAM and most buyers require.
Meeting Global Buyer ESG Requirements
Beyond the EU, brand owners and retailers ask suppliers for carbon disclosure, science-based targets and decarbonization roadmaps. A verified organizational inventory is the foundation for SBTi target setting (commit, develop, submit, announce, disclose) and for responding to customer ESG questionnaires without rework.
Steps to Get Export-Ready
First, define your organizational boundary and collect activity data for energy, materials and logistics. Second, quantify emissions in CO2e using recognized factors. Third, commission independent verification under ISO 14064-3. Fourth, prepare product-level studies for CBAM-covered goods under ISO 14067. Finally, maintain annual re-verification so your data stays current for every shipment.
Common Export Questions
Q: Does CBAM apply to all exports to the EU?
A: No. CBAM currently covers only the six named sectors (cement, aluminium, fertilisers, iron and steel, hydrogen and electricity). Other products are not in scope, but buyers across all sectors may still request carbon data voluntarily.
Q: Can I use estimated or self-declared emissions for CBAM?
A: Embedded emissions used for CBAM must be verified. Self-declared or unverified estimates do not meet the requirement, and importers carry the compliance risk if the underlying data is not defensible.
Q: How should a small exporter start?
A: Start with an ISO 14064-1 organizational inventory for your main site. It builds the data and process you need for product studies and CBAM later, and it answers the majority of buyer requests at the lowest cost.
