Sustainability due diligence export finance

Sustainability due diligence export finance refers to the environmental, social and human rights reviews that condition officially supported export credits, and to overlapping corporate sustainability due diligence duties that large companies may owe across their operations and chains of activities.

Two institutional layers matter for bank and ECA desks. The OECD Recommendation on Common Approaches for Officially Supported Export Credits and Environmental and Social Due Diligence sets shared procedures for Adherents' export credit agency decision making. Separately, Directive (EU) 2024/1760 on corporate sustainability due diligence (CSDDD), as amended by the Omnibus I package including Directive (EU) 2026/470, imposes company level duties on in scope EU and non EU companies.

Sustainability due diligence export finance under the Common Approaches

The Common Approaches, updated by OECD Council adoption on 20 March 2024, require screening of applications for officially supported export credits, classification of in scope projects into Categories A, B and C, and environmental and social review benchmarked to international standards. The Adherent's share threshold of SDR 10 million, sensitive area location, and likelihood of severe project related human rights impacts determine how far review must go.

Category A projects require an ESIA. Reviews benchmark against IFC Performance Standards or, for sovereign obligors, World Bank Environmental and Social Standards, plus relevant EHS Guidelines, while always requiring host country legal compliance. Limited or non recourse project finance Category A transactions carry additional expectations on independent expertise. Category A impact information should be disclosed at least 30 calendar days before final commitment.

Those steps are due diligence for official support eligibility and conditioning. They sit beside financial term disciplines under the OECD Arrangement. An ECA such as UKEF applies national procedures that implement the Recommendation when exporters or lenders seek official cover or lending support for capital goods and services.

Corporate CSDDD duties

Directive (EU) 2024/1760 entered into force on 25 July 2024. The European Commission states that Omnibus I amendments, including Directive (EU) 2026/470 published on 26 February 2026 and in force from 18 March 2026, simplify and retarget the regime. Under the amended scope described by the Commission, large EU companies with at least 5,000 employees and EUR 1.5 billion net worldwide turnover, and large non EU companies with at least EUR 1.5 billion net turnover in the EU, fall in scope, including on a consolidated basis for ultimate parent companies of groups where the Directive so provides.

In scope companies must identify and address actual and potential adverse human rights and environmental impacts in their own operations, those of subsidiaries, and in their chains of activities, with complaints mechanisms, monitoring and public communication. Following Omnibus I, companies may focus on areas where impacts are most likely and most severe, based on reasonably available information. Member States must transpose CSDDD related Omnibus amendments by 26 July 2028 and apply them from 26 July 2029, except Article 16 reporting measures that apply for financial years starting on or after 1 January 2030.

Administrative supervision and civil liability under national law enforce the duty. The Commission states that the maximum limit for pecuniary penalties is set at 3 percent of the company's net worldwide turnover for the most serious violations.

CSDDD is company law due diligence. It is not an ECA product rule. Banks and exporters that are in scope entities must comply as companies. ECA Common Approaches still apply when official support is requested, regardless of whether the exporter is above CSDDD thresholds.

How the layers interact

Export finance transactions can therefore face parallel tracks. ECA support requires Common Approaches screening and, where applicable, classification and review of the project or existing operation. Corporate groups in CSDDD scope must run ongoing due diligence across chains of activities that may include the same export project, suppliers and downstream partners.

Standards overlap in substance: human rights, labour, environment and climate related impacts appear in both IFC aligned ECA reviews and CSDDD annexes of rights and prohibitions under the Directive. Process differs. Common Approaches are transaction gated for official support. CSDDD is an ongoing corporate duty with administrative and liability consequences under national transposition.

Neither framework replaces the other. Host country permits and criminal law remain independent. Private bank environmental and social policies on covered lending may add a third track when commercial banks fund ECA backed loans.

Bank roles on covered transactions

Commercial banks arranging buyer credit or supplier credit facilities with official support sit between ECA conditions and borrower covenants. Cover documents may require compliance with environmental and social action plans derived from the Common Approaches review. Facility agreements then carry those plans into drawstop, reporting and covenant breach mechanics for the lending syndicate. That transmission is contractual. It does not merge CSDDD corporate duties into the loan automatically.

Where the arranging bank or exporter is itself a CSDDD in scope company, internal sustainability due diligence programmes must still map severe impact risks across chains of activities that include the financed export. Information requests to SMEs in the chain are constrained under the Directive's burden limiting provisions as described by the Commission. ECA ESIA packages can supply useful project level information but do not discharge the company's ongoing duty.

Climate and human rights themes appear in both layers. Common Approaches reviews consider greenhouse gas and social impacts among environmental and social factors, and call for specific human rights due diligence where severe impacts are likely. CSDDD annexes catalogue rights and prohibitions that inform corporate identification of adverse impacts. Equivalence of outcome is not automatic: a project cleared for ECA support can still raise corporate due diligence issues elsewhere in a group's chain of activities, and vice versa.

Institutional summary

Sustainability due diligence export finance is the combined institutional practice of OECD Common Approaches reviews on officially supported export credits and corporate sustainability due diligence regimes such as the amended EU CSDDD. Credit and cover decisions still turn on ECA eligibility, Arrangement financial terms and bank credit analysis. Sustainability due diligence determines whether environmental and social risks have been identified, classified and conditioned to the standards each regime requires.
