Scope 3 Emissions Reporting refers to the mandatory disclosure of indirect greenhouse gas emissions generated throughout the entire value chain of a company’s products or services, as defined under the Carbon Border Adjustment Mechanism (CBAM) established by Regulation (EU) 2023/956. These emissions include all upstream and downstream activities not directly controlled by the reporting company but linked to its operations, such as raw material extraction, transportation, product use, and end-of-life disposal. The reporting obligation aims to ensure transparency and accountability in carbon-intensive supply chains, enabling the EU to implement effective carbon pricing and border adjustment policies in line with the European Green Deal objectives.
Scope 3 Emissions Reporting Compliance under the Carbon Border Adjustment Mechanism
The Scope 3 Emissions Reporting requirement applies primarily to importers of goods covered by the Carbon Border Adjustment Mechanism (CBAM), which targets carbon-intensive products entering the European Union market. The CBAM, introduced by Regulation (EU) 2023/956 and published in the Official Journal on 15 May 2023, mandates that importers report the embedded emissions of their imported goods, including indirect emissions from their entire supply chain (Scope 3), to ensure a level playing field with EU producers subject to the EU Emissions Trading System (ETS).
Companies subject to this obligation must calculate, verify, and report their Scope 3 emissions annually, starting from the transitional reporting phase on 1 January 2026. Failure to comply with these requirements may result in penalties of up to 5% of the company’s global annual turnover, as stipulated in Article 30 of the regulation.
Who Must Comply with Scope 3 Emissions Reporting?
The Scope 3 emissions reporting obligation under the CBAM applies to:
- Importers of goods listed in Annex I of Regulation (EU) 2023/956, including cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen.
- Companies with an annual import volume exceeding 10,000 tonnes CO2 equivalent embedded emissions in the EU market.
- Entities registered in the EU or third-country exporters whose goods are imported into the EU through registered importers.
Notably, the reporting obligation covers all indirect emissions in the supply chain, including upstream activities such as raw material extraction, manufacturing processes, and transportation, as well as downstream activities like product use and disposal.
Exact Obligations for Scope 3 Emissions Reporting
Under Regulation (EU) 2023/956, importers must:
- Calculate the embedded Scope 3 emissions associated with each product imported into the EU, using standardized methodologies outlined in the delegated acts accompanying the CBAM regulation.
- Submit an annual emissions report to the European Commission via the CBAM registry, detailing the total Scope 3 emissions per product category.
- Ensure third-party verification of emissions data by accredited verifiers to guarantee accuracy and compliance.
- Maintain comprehensive documentation of emissions calculations, data sources, and verification reports for audit purposes for at least 10 years.
Importers must also update their emissions data annually by 31 March for the previous calendar year, starting with the reporting year 2026.

Scope 3 Emissions Reporting vs. Scope 1 and 2: Key Differences
| Emission Scope | Definition | Reporting Responsibility | Examples |
|---|---|---|---|
| Scope 1 | Direct emissions from owned or controlled sources. | Company itself. | Fuel combustion on-site, company vehicles. |
| Scope 2 | Indirect emissions from purchased electricity, heat, or steam. | Company itself. | Electricity used in manufacturing facilities. |
| Scope 3 | All other indirect emissions in the value chain. | Importers under CBAM for imported goods. | Raw material extraction, transportation, product use, disposal. |
Practical Compliance Checklist for Scope 3 Emissions Reporting
- Identify all relevant upstream and downstream activities contributing to Scope 3 emissions for each imported product.
- Gather accurate data from suppliers, logistics providers, and end-users to quantify emissions.
- Apply the standardized CBAM calculation methodologies as per delegated acts.
- Engage accredited third-party verifiers early to review emissions data and methodologies.
- Register in the CBAM registry before the first reporting deadline (31 March 2027).
- Submit verified annual emissions reports on time via the CBAM registry.
- Maintain detailed records and verification reports for audit and compliance purposes.
- Prepare for purchasing CBAM certificates starting 1 January 2027 based on reported emissions.
Truth Anchor: According to Article 30 of Regulation (EU) 2023/956, non-compliance with Scope 3 emissions reporting can lead to penalties of up to 5% of the company’s global annual turnover and suspension of import rights, emphasizing the critical importance of timely and accurate reporting.
Frequently Asked Questions
What exactly are Scope 3 emissions under the CBAM?
Scope 3 emissions include all indirect greenhouse gas emissions in a company’s value chain that are not owned or directly controlled by the company. Under the CBAM, this means emissions from raw material extraction, manufacturing, transportation, product use, and disposal related to imported goods.
Who is required to report Scope 3 emissions?
Importers of goods listed in Annex I of Regulation (EU) 2023/956 with embedded emissions exceeding 10,000 tonnes CO2 equivalent annually must report Scope 3 emissions starting from the 2026 reporting year.
How do I calculate Scope 3 emissions for my imported products?
Calculations must follow the methodologies specified in the CBAM delegated acts, which require gathering data from all upstream and downstream processes and applying standardized emission factors to quantify total indirect emissions.
What are the deadlines for submitting Scope 3 emissions reports?
The first mandatory report covering the 2026 calendar year must be submitted by 31 March 2027. Annual reports are due by 31 March each year thereafter.
What penalties apply if I fail to comply with Scope 3 emissions reporting?
Penalties include fines up to 5% of global annual turnover, suspension of import rights, and reputational damage, as per Article 30 of Regulation (EU) 2023/956.
