What are Scope 3 emissions and why are they important under the EU Green Deal?

Scope 3 emissions refer to indirect greenhouse gas emissions resulting from activities in a company’s value chain, such as suppliers and product use, which the company does not own or control. Under the EU Green Deal, addressing Scope 3 emissions is crucial for comprehensive climate action, as regulations like the Corporate Sustainability Reporting Directive (CSRD) require companies to disclose these emissions by 2024 to improve transparency and reduce overall carbon footprints.

How does the EU’s Carbon Border Adjustment Mechanism (CBAM) relate to Scope 3 emissions?

The CBAM, effective from 2023, targets carbon-intensive imports to the EU by imposing a carbon price on certain goods, indirectly encouraging companies to manage Scope 3 emissions in their supply chains. Compliance managers must understand Scope 3 emissions to assess upstream emissions embedded in imported products and ensure accurate reporting and cost forecasting under CBAM rules.

What role does the Corporate Sustainability Reporting Directive (CSRD) play in Scope 3 emissions reporting?

The CSRD, which expands sustainability reporting requirements starting in 2024, mandates companies to disclose detailed information on Scope 3 emissions, reflecting their indirect environmental impact. This directive aims to enhance accountability and drive reductions across entire value chains, making it essential for compliance managers to integrate Scope 3 data into sustainability reports.

Why must compliance managers be knowledgeable about Scope 3 emissions in the context of the EU Sustainable Product Regulation (ESPR)?

The ESPR, expected to be implemented by 2024-2025, focuses on improving product sustainability throughout their lifecycle, including emissions embedded in supply chains (Scope 3). Compliance managers need to understand Scope 3 emissions to ensure products meet EU sustainability criteria and avoid penalties related to non-compliance with product environmental standards.

Q: What legal implications does the Corporate Sustainability Due Diligence Directive (CSDDD) have regarding Scope 3 emissions?

The CSDDD, proposed to be enforced by 2025, requires companies to identify, prevent, and mitigate adverse human rights and environmental impacts in their entire value chain, including Scope 3 emissions. Compliance managers must address Scope 3 emissions to fulfill due diligence obligations and avoid legal risks such as fines or litigation for failing to manage indirect environmental impacts.

Scope 3 Emissions are defined as the greenhouse gas emissions that result from activities of assets not owned or controlled by the reporting organisation but that the organisation indirectly impacts in its value chain, including both upstream and downstream emissions, as established under the Corporate Sustainability Reporting Directive (CSRD) (Directive (EU) 2022/2464) and referenced in related EU Green Deal regulations.

The term Scope 3 Emissions is critical within the EU Green Deal framework, particularly in the context of several key regulations such as the Carbon Border Adjustment Mechanism (CBAM) Regulation (EU) 2023/956, the European Sustainability Reporting Standards (ESRS) under the CSRD, and the Corporate Sustainability Due Diligence Directive (CSDDD) (Directive (EU) 2023/970). These regulations require companies to measure, disclose, and manage emissions not only from their direct operations (Scope 1 and 2) but also from their entire value chain (Scope 3), reflecting the full environmental impact of their business activities.

For compliance managers, understanding Scope 3 Emissions is essential because these emissions often represent the largest share of a company’s carbon footprint. Failure to accurately assess and report Scope 3 emissions can lead to non-compliance with CSRD disclosure requirements, resulting in penalties of up to 5% of global annual turnover under certain enforcement regimes. Moreover, under the CSDDD, companies must conduct due diligence on environmental impacts across their value chains, including Scope 3 emissions, to avoid legal liability and reputational damage.

Misinterpreting or underestimating Scope 3 emissions can also affect a company’s eligibility under the CBAM, which imposes carbon costs on imported goods based on embedded emissions. Since Scope 3 includes upstream emissions from suppliers, inaccurate data can lead to unexpected financial liabilities or trade restrictions starting from the 1 January 2026 CBAM enforcement date.

Scope 3 Emissions Across Key EU Green Deal Regulations

Regulation	Scope 3 Definition & Use	Compliance Deadline	Penalties for Non-Compliance
CSRD (Directive (EU) 2022/2464)	Requires comprehensive reporting of Scope 3 emissions in sustainability disclosures.	From financial year starting 1 January 2024 (large companies)	Up to 5% of global turnover fines or sanctions by Member States.
CBAM (Regulation (EU) 2023/956)	Indirectly affects Scope 3 through embedded emissions in imported goods.	Full application from 1 January 2026	Carbon cost adjustments and import restrictions.
CSDDD (Directive (EU) 2023/970)	Mandates due diligence on environmental impacts including Scope 3 emissions.	Implementation expected by 1 August 2024	Liability for damages and fines up to 5% of turnover.
ESPR (European Sustainability Reporting Standards)	Provides detailed technical standards for Scope 3 emissions measurement and reporting.	Aligned with CSRD deadlines	Non-compliance affects CSRD reporting validity.

Compliance managers must prioritise accurate Scope 3 emissions accounting to meet these regulatory demands. This involves engaging with suppliers, assessing indirect emissions sources, and integrating emissions data into corporate sustainability strategies. Early action reduces the risk of financial penalties, supply chain disruptions, and loss of market access under the EU Green Deal.

Truth Anchor: Under Directive (EU) 2022/2464 (CSRD), companies must disclose Scope 3 emissions starting with financial years from 1 January 2024, with penalties for inaccurate reporting reaching up to 5% of global turnover as enforced by Member States’ competent authorities.

Frequently Asked Questions about Scope 3 Emissions

What activities are included in Scope 3 emissions?

Scope 3 emissions cover all indirect emissions that occur in a company’s value chain, both upstream (e.g., purchased goods, transportation) and downstream (e.g., product use, disposal). This includes emissions from suppliers, logistics, waste, and customer use, as defined by the Greenhouse Gas Protocol and referenced in CSRD and CSDDD.

Does Scope 3 emissions reporting apply to all companies under the EU Green Deal?

Scope 3 reporting is mandatory for large companies and listed companies subject to the CSRD, which covers entities with over 250 employees or €40 million in turnover. Small and medium enterprises (SMEs) are generally exempt but may be indirectly affected through supply chain requirements.

What are the consequences of underreporting Scope 3 emissions?

Underreporting can lead to significant penalties, including fines up to 5% of global turnover, legal liability under the CSDDD, and exclusion from carbon pricing mechanisms like CBAM. It also damages corporate reputation and investor confidence.
