Banking Law And Criminal Law Aspects Of Sustainable Finance Spain

Introduction

Sustainable finance in Spain refers to the integration of environmental, social, and governance (ESG) considerations into financial decision-making, banking activities, investment processes, and corporate financing.

The development of sustainable finance has created new legal responsibilities for banks and financial institutions. Spanish banks are increasingly required to consider climate risks, environmental impacts, sustainability disclosures, and responsible lending practices when providing financing.

However, sustainable finance also creates important criminal-law issues. Financial institutions, directors, executives, and other market participants may face criminal liability where sustainability-related information is misleading, fraudulent, or used to obtain financial benefits through deception.

Criminal law aspects of sustainable finance mainly concern:

• Greenwashing.

• Fraudulent ESG disclosures.

• Misrepresentation of sustainable investments.

• Corruption in environmental projects.

• Market manipulation.

• Misuse of climate-related financial information.

• Breach of directors’ duties.

Spain’s sustainable-finance framework operates within European Union financial regulation, including the EU Sustainable Finance Disclosure Regulation (SFDR), EU Taxonomy Regulation, Corporate Sustainability Reporting Directive (CSRD), and banking supervisory standards.

The main objectives are:

• Promoting responsible investment.

• Preventing environmental financial fraud.

• Protecting investors.

• Improving transparency.

• Ensuring accountability of financial institutions.

1. Legal And Regulatory Framework

Sustainable finance regulation in Spain is based on Spanish law and European Union financial legislation.

Important legal sources include:

• Spanish Criminal Code.

• Spanish Securities Market legislation.

• Banking supervision rules.

• EU Sustainable Finance Disclosure Regulation (SFDR).

• EU Taxonomy Regulation.

• Corporate Sustainability Reporting Directive (CSRD).

• European Central Bank climate-risk supervisory expectations.

• European Banking Authority (EBA) sustainability guidelines.

These rules require financial institutions to disclose information regarding:

• Environmental risks.

• Sustainability characteristics of investments.

• Climate-related financial risks.

• ESG policies.

• Governance arrangements.

The purpose is to ensure that investors and customers receive accurate sustainability information.

2. Concept Of Sustainable Finance In Banking Law

Sustainable finance involves directing financial resources toward activities that contribute to:

• Environmental protection.

• Climate transition.

• Social development.

• Responsible corporate governance.

Banks participate in sustainable finance through:

• Green loans.

• Sustainability-linked loans.

• Green bonds.

• Renewable energy financing.

• Climate-risk assessment.

• ESG investment products.

However, sustainable finance creates legal risks when financial institutions provide inaccurate information about the sustainability characteristics of products or projects.

3. Criminal Law Risks In Sustainable Finance

Criminal law becomes relevant where sustainability-related conduct involves intentional wrongdoing.

Major criminal risks include:

A. Greenwashing Fraud

Greenwashing occurs when companies or financial institutions falsely present products, investments, or projects as environmentally sustainable.

Examples include:

• False claims about carbon neutrality.

• Misleading statements regarding renewable projects.

• Incorrect ESG ratings.

• False sustainability reports.

Where investors suffer losses due to deceptive information, criminal fraud provisions may apply.

B. Fraud In Sustainable Investment Products

Financial institutions may face criminal liability where they:

• Misrepresent investment risks.

• Provide false ESG information.

• Hide environmental problems.

• Encourage investment through misleading sustainability claims.

Spanish criminal fraud provisions may apply where deception causes economic damage.

C. False Corporate Reporting

Companies and banks increasingly publish sustainability reports.

Criminal liability may arise if reports contain:

• Intentionally false information.

• Material omissions.

• Misleading statements affecting investors.

Directors and executives may become responsible where they approve inaccurate disclosures.

D. Corruption In Green Projects

Large sustainable-finance projects often involve:

• Renewable energy infrastructure.

• Public subsidies.

• Government contracts.

• Carbon-credit systems.

Corruption risks include:

• Improper payments.

• Manipulation of permits.

• Fraudulent allocation of environmental funds.

4. ESG Disclosure Obligations And Criminal Responsibility

Spanish banks and companies must provide accurate sustainability information.

Disclosure obligations require:

• Transparency.

• Reliability.

• Consistency.

• Verification.

False ESG disclosures may create liability under:

• Fraud offences.

• Corporate crimes.

• Market-abuse rules.

• Accounting-related offences.

The importance of accurate disclosure has increased because investors increasingly rely on ESG information when making financial decisions.

5. Climate Risk And Banking Governance

Climate-related financial risk has become a major governance responsibility for Spanish banks.

Banks must consider:

• Physical climate risks.

• Transition risks.

• Regulatory changes.

• Environmental liabilities.

Board responsibilities include:

• Approving ESG strategies.

• Monitoring climate risks.

• Ensuring accurate disclosures.

• Maintaining compliance systems.

Governance failures may occur when directors:

• Ignore climate-related risks.

• Approve misleading sustainability claims.

• Fail to establish proper controls.

6. Sustainable Finance And Money Laundering Risks

Sustainable finance products may also create AML risks.

Examples include:

• Misuse of green investment funds.

• Fraudulent carbon-credit transactions.

• Concealment of illegal environmental activities.

Banks must apply:

• Customer due diligence.

• Transaction monitoring.

• Risk-based controls.

• Internal compliance systems.

7. Criminal Liability Of Banks And Directors

Spanish law may impose responsibility on:

Banks

Banks may face consequences where they:

• Commit financial fraud.

• Mislead customers.

• Fail to comply with regulatory obligations.

Directors And Executives

Executives may face personal liability where they:

• Approve false reports.

• Hide material risks.

• Manipulate sustainability information.

• Breach fiduciary duties.

Corporate governance therefore plays a central role in preventing ESG-related criminal offences.

8. Role Of Supervisory Authorities

Several institutions supervise sustainable-finance activities.

Bank Of Spain

Responsible for banking supervision and financial stability.

CNMV

Supervises securities markets and investment disclosures.

European Central Bank

Supervises significant Spanish banks and climate-risk management.

European Supervisory Authorities

Develop ESG disclosure and risk-management standards.

Supervisors focus on:

• Transparency.

• Risk management.

• Consumer protection.

• Market integrity.

9. Sustainable Finance And Market Abuse

ESG information can affect financial markets.

Criminal and regulatory concerns arise where:

• False climate information influences share prices.

• Companies manipulate ESG ratings.

• Insiders misuse sustainability information.

Market-abuse rules apply where ESG information becomes material information for investors.

10. Green Bonds And Criminal Risks

Green bonds are financial instruments used to fund environmentally beneficial projects.

Spanish banks participate in green-bond markets through:

• Issuance.

• Underwriting.

• Investment.

Criminal risks include:

• Misuse of proceeds.

• False environmental claims.

• Failure to complete promised projects.

Investors depend on accurate information regarding the environmental use of funds.

11. Sustainable Finance And Corporate Criminal Liability

Under Spanish corporate criminal liability rules, companies may be responsible for offences committed:

• By managers.

• By representatives.

• Due to inadequate compliance systems.

Banks and financial institutions therefore require:

• ESG compliance programs.

• Internal investigations.

• Employee training.

• Whistleblowing systems.

12. Compliance Systems And Prevention

Effective compliance systems help prevent sustainable-finance crimes.

Important measures include:

• ESG risk assessments.

• Internal controls.

• Audit procedures.

• Verification of sustainability claims.

• Employee education.

• Monitoring of environmental projects.

A strong compliance culture reduces criminal and regulatory risks.
