Embedded emissions are the greenhouse gases released across the production chain of a good — from raw material extraction through manufacturing — that are then "embedded" in the final product when it is shipped or sold. Verification refers to the procedures by which those emissions are quantified, documented by the producer, and checked by an accredited third party before being accepted by a regulator or buyer.
The concept has gained policy weight through carbon border measures. Under the EU's Carbon Border Adjustment Mechanism (CBAM), adopted in Regulation (EU) 2023/956, importers of cement, iron and steel, aluminium, fertilisers, electricity and hydrogen must report embedded emissions during a transitional phase that began on 1 October 2023, with financial obligations starting in 2026. From the definitive phase, those declarations must be verified by accredited verifiers using methodologies set out in implementing regulations.
Verification typically involves:
- Producer-level data collection at the installation where the good was made, covering direct (Scope 1) and, for some sectors, certain indirect (Scope 2) emissions.
- Application of a defined methodology, such as monitoring and reporting rules modelled on the EU Emissions Trading System.
- Independent audit by a body accredited under standards such as ISO 14065 or national equivalents, checking data quality, system boundaries, and calculation accuracy.
- Use of default values where verified primary data is unavailable, often set at conservative levels to discourage reliance on them.
Embedded emissions verification matters because carbon pricing only deters leakage if the emissions attributed to imports are credible. Without robust verification, exporters could under-report and undermine the level playing field that border adjustments aim to create. The same logic underpins emerging product carbon footprint rules, green public procurement standards, and voluntary schemes such as ResponsibleSteel and the IAI aluminium protocols. Developing-country exporters have raised concerns about the administrative cost and the availability of qualified verifiers in their jurisdictions.
Example
In 2024, Indian and Turkish steel exporters began contracting EU-accredited verifiers to certify embedded emissions data for shipments covered by the CBAM transitional reporting phase.
Frequently asked questions
Corporate reporting covers a company's overall footprint, often annually. Embedded emissions verification is product- or shipment-specific, attributing emissions to a defined good for trade or procurement purposes.
