1. Introduction

“Green Industrial Policy Banking” in Spain can be understood as the interaction between banking regulation, sustainable finance, industrial policy, climate-transition law, and public/private financing used to move industrial activity toward lower-carbon and environmentally sustainable production.

Spain does not have one statute formally called a “Green Industrial Policy Banking Act.” Instead, the legal framework is spread across Spanish banking legislation, Law 7/2021 on Climate Change and Energy Transition, sustainable-finance rules, EU banking law, EU State-aid law, environmental regulation, and EU sustainable-finance legislation. The Banco de España currently identifies Law 2/2011 on Sustainable Economy and Law 7/2021 among the principal Spanish sustainable-finance laws.

The basic idea is simple: banks remain commercial financial institutions, but climate and environmental risks increasingly form part of the legal and prudential framework within which they decide how industrial projects are financed.

2. Meaning of Green Industrial Policy Banking

Green industrial policy seeks to encourage economic activities such as:

• renewable-energy manufacturing;
• industrial energy efficiency;
• clean transportation;
• low-carbon manufacturing;
• electricity-grid infrastructure;
• building renovation;
• circular-economy projects;
• industrial decarbonisation;
• clean technologies; and
• environmentally sustainable infrastructure.

Banks become important because industrial transformation normally requires substantial long-term capital.

For example, suppose a Spanish manufacturer wants to replace an emissions-intensive production system with lower-carbon technology. The project may require a bank loan, syndicated financing, guarantees, public financing or bond-market funding.

Banking law determines matters such as the bank's risk management, capital requirements and supervision. Climate legislation adds another dimension: the bank may have to evaluate how climate-transition risks affect its loan and investment portfolios.

3. Law 7/2021 on Climate Change and Energy Transition

The Ley 7/2021, de cambio climático y transición energética is particularly important.

Its structure expressly connects climate policy with financial resources, public procurement and the financial system. Title VII contains provisions dealing with public resources, public procurement, integration of climate risk by credit institutions and integration of climate risk into the financial system.

This creates a legal connection between:

industrial transition → financing → banks → climate-risk management.

The law therefore does more than regulate industrial emissions directly. It also addresses how climate transition affects financial institutions.

4. Climate Risk as a Banking Risk

Article 32 of Law 7/2021 is especially important for banks.

Spanish credit institutions and consolidated banking groups covered by the provision must include an annual assessment of the financial impact of climate-related risks within their prudentially relevant information. This includes risks resulting from the transition toward a sustainable economy.

Consequently, an industrial loan cannot always be analysed exclusively through conventional factors such as:

profitability + collateral + borrower creditworthiness.

Climate-related factors may also matter, including:

transition risk + physical climate risk + regulatory change + technological change + carbon exposure.

For industrial banking, this is significant because sectors undergoing rapid decarbonisation can present material transition risks.

5. Decarbonisation of Bank Portfolios

Law 7/2021 goes further.

Article 32 provides that credit institutions must publish specific decarbonisation objectives for their lending and investment portfolios aligned with the Paris Agreement, applicable from 2023.

This does not mean Spanish law simply prohibits banks from lending to every carbon-intensive business.

Rather, it creates a framework in which banks increasingly need to understand and disclose the climate characteristics and transition exposure of their portfolios.

For industrial policy, this can influence capital allocation over time. Financing may increasingly distinguish between:

• an industrial company with a credible transition strategy;
• a company investing in cleaner production;
• a project already aligned with low-carbon technologies; and
• an industrial borrower whose business model faces substantial transition risk.

6. Prudential Regulation

Green industrial lending remains subject to ordinary banking law.

Spanish banks cannot disregard prudential standards simply because a project has environmental benefits. A green industrial loan remains a credit exposure.

Banks therefore continue to consider:

• probability of default;
• expected losses;
• collateral;
• concentration risk;
• liquidity;
• maturity;
• borrower cash flows;
• capital adequacy; and
• governance.

Spanish banking legislation also gives supervisory authorities tools for dealing with excessive risks. These can include requiring additional provisioning or particular treatment of assets, restricting activities creating excessive risks, and requiring institutions to reduce risks associated with their activities, products or systems.

Thus:

Green purpose does not eliminate prudential banking requirements.

7. Banco de España and Systemic Climate Risk

Article 33 of Law 7/2021 establishes another important mechanism.

The Banco de España, CNMV and Directorate-General for Insurance and Pension Funds are required jointly, every two years, to prepare an assessment concerning alignment with Paris Agreement and EU climate objectives and the risks that climate change and climate policies create for the Spanish financial system.

This demonstrates that climate change is not treated only as an environmental-policy issue.

It is also potentially a financial-stability issue.

For example, if a substantial part of bank lending were concentrated in industries whose assets rapidly lost value because of decarbonisation policies, the resulting losses could have implications beyond individual borrowers.

8. Public Development Banking and ICO

Spain's green industrial policy also involves public financial institutions, particularly the Instituto de Crédito Oficial (ICO).

Public development finance can complement commercial-bank financing through loans, guarantees, bond financing and other mechanisms supporting investment.

ICO's Green Bond Framework identifies activities connected with climate and sustainable investment and describes commitments including reducing portfolio carbon footprints, engaging customers in the transition toward a low-carbon economy, developing climate-impact methodologies and establishing portfolio-alignment objectives.

This illustrates how public banking and capital-market instruments can support Spain's broader industrial transition.

9. EU Law Is Essential

Spanish green industrial banking cannot be understood purely through Spanish legislation.

Spain operates within the EU legal and banking framework. Relevant areas include:

EU prudential banking law — governing bank capital, risk management and supervision.

EU sustainable-finance rules — helping identify and disclose environmentally sustainable economic activities.

EU disclosure legislation — requiring specified sustainability-related information.

EU State-aid rules — restricting selective economic advantages granted by Member States unless compatible with EU law.

EU competition law — relevant when industrial-financing arrangements affect competition.

This EU dimension is particularly important where the Spanish State financially supports particular industries or technologies.

Important Case Laws

There is limited Spanish jurisprudence dealing specifically with a legal category called “green industrial policy banking.” It would therefore be misleading to invent cases under that title.

The relevant jurisprudence instead comes from interconnected areas such as renewable-energy regulation, environmental policy, banking, taxation, State aid and investment protection.

10. Banco Santander and Santusa v Commission — T-12/15 and Joined Cases

General Court, judgment of 27 September 2023

This litigation concerned a Spanish tax measure allowing certain companies to amortise financial goodwill connected with acquisitions of shareholdings in foreign companies.

The European Commission regarded the relevant scheme as unlawful State aid and ordered recovery, generating extensive litigation concerning State aid, legal certainty and legitimate expectations. The General Court proceedings included Banco Santander and related applicants.

Relevance

Although this was not a green-finance case, it is highly relevant to the legal design of green industrial policy.

If Spain provides selective financial or fiscal advantages to particular industrial undertakings, technologies or investments, policymakers must consider EU State-aid law.

The broader lesson is:

Environmental objectives do not automatically remove State-aid constraints.

A green industrial financing programme must therefore be structured consistently with EU competition and State-aid requirements.

11. Asociación Nacional de Grandes Empresas de Distribución (ANGED) Cases

The CJEU considered several disputes concerning Spanish regional environmental taxes imposed on large retail establishments, including questions concerning whether exemptions could amount to State aid.

Relevance

These cases illustrate the difficult boundary between:

environmental taxation + industrial/economic policy + selective economic advantages + EU State-aid law.

The principle is relevant to green industrial banking because preferential financial treatment can also raise selectivity questions.

12. Asociación Española de la Industria Eléctrica (UNESA) and Related Energy-Tax Litigation

Spanish energy taxation has generated substantial litigation before national courts and the CJEU concerning taxes and charges imposed within the electricity sector.

Relevance

Electricity prices and energy taxation directly affect the economics of industrial decarbonisation.

A bank financing an energy-intensive industrial facility must therefore consider regulatory risks associated with:

• electricity taxation;
• renewable-energy policy;
• carbon costs;
• energy-market reforms; and
• changes in environmental regulation.

The cases demonstrate how regulatory policy can alter the financial assumptions underlying industrial investments.

13. Elecdey Carcelen SA and Others v Comunidad Autónoma de Castilla-La Mancha — C-215/16 etc.

These CJEU proceedings concerned Spanish regional charges associated with wind-energy installations.

The litigation raised questions about the relationship between national environmental/energy measures and EU renewable-energy and fiscal legislation.

Relevance

Wind installations frequently require substantial project financing.

The case demonstrates an important principle for green banking:

A project may qualify as renewable or environmentally desirable while still being exposed to taxes, regulatory charges and changes in national or regional legislation.

Banks therefore need regulatory-risk analysis when financing renewable industrial infrastructure.

14. Eólica del Principado SA v Principado de Asturias — C-727/17

This dispute also concerned taxation affecting wind-energy activities in Spain.

Relevance

The judgment illustrates the interaction among renewable-energy investment, regional taxation and EU law.

For lenders, taxation can change:

project revenues → debt-service capacity → project valuation → credit risk.

Consequently, green project finance remains subject to ordinary financial-risk analysis.

15. Asociación Española de la Industria Eléctrica (UNESA) — C-80/18 to C-83/18

These joined proceedings involved Spanish measures concerning electricity production and environmental taxation.

Relevance

They are useful for understanding the broader legal environment surrounding the financing of electricity and industrial-energy infrastructure.

They demonstrate that green industrial investment exists inside a multilayered system consisting of:

EU law + national legislation + autonomous-community rules + taxation + energy regulation.

For banks, this regulatory complexity can become a component of credit and transition risk.

16. Infrastructure and Renewable-Energy Investment Arbitration — Charanne v Spain

Charanne B.V. and Construction Investments S.A.R.L. v Kingdom of Spain

This arbitration arose from changes Spain made to its renewable-energy support regime.

Investors argued that regulatory changes adversely affected investments in the photovoltaic sector.

The tribunal did not accept all of the investors' claims.

Banking relevance

The dispute became an important illustration of regulatory-change risk.

Suppose a bank finances a renewable-energy project based heavily on regulated tariffs. If those rules change, expected project revenues can change substantially.

Therefore lenders must evaluate:

regulatory stability → expected cash flow → debt-service capacity → creditworthiness.

17. Eiser Infrastructure Limited v Kingdom of Spain

This investment arbitration also arose from changes to Spain's renewable-energy regulatory framework.

Unlike Charanne, the tribunal originally found liability against Spain and awarded compensation, although the award was subsequently annulled.

Relevance

The history of the dispute illustrates why banks financing green infrastructure cannot assume that public-support arrangements will remain unchanged throughout a project's lifetime.

Regulatory and legal due diligence therefore becomes an important part of green industrial financing.

18. Green Industrial Lending Process

A Spanish bank considering financing for a green industrial project can conceptually analyse several layers.

Stage 1 — Borrower assessment

The bank examines:

• financial statements;
• leverage;
• cash flow;
• repayment ability;
• collateral; and
• management.

Stage 2 — Project assessment

It examines:

• technology;
• construction risks;
• operating costs;
• projected revenues; and
• project lifetime.

Stage 3 — Environmental and regulatory assessment

The lender may consider:

• environmental permits;
• climate-transition risks;
• emissions exposure;
• energy regulation;
• environmental liabilities; and
• expected regulatory changes.

Stage 4 — Sustainable-finance classification

Where relevant, the financing may need assessment against applicable EU sustainable-finance criteria.

Stage 5 — Prudential treatment

The bank determines the appropriate treatment of the credit exposure under applicable banking rules.

Stage 6 — Monitoring

Climate and transition risks can continue after the loan is granted. Banks therefore may need continuing information about the borrower's transition strategy and financial position.

19. Greenwashing Risk

Green industrial banking also creates greenwashing risk.

A loan or financial product should not be presented as environmentally sustainable merely because the borrower operates in an industry associated with the green transition.

The actual financed activity matters.

For example, financing a company that manufactures both conventional and low-carbon products raises questions about:

• use of proceeds;
• environmental objectives;
• performance indicators;
• disclosure;
• verification; and
• continuing compliance.

This is one reason sustainable-finance regulation increasingly emphasises reliable sustainability information.

20. Relationship with Public Procurement

Law 7/2021 also connects climate policy with Spanish public procurement. Its Title VII expressly includes both public procurement and financial-system climate-risk provisions.

This matters because government demand can stimulate green industries.

For example:

Government green procurement → increased demand for clean industrial products → new industrial investment → demand for bank financing.

Thus procurement policy and banking policy can reinforce one another without becoming the same legal regime.

21. Transition Risk and Physical Risk

Spanish green industrial banking should distinguish two important categories.

Physical climate risk concerns direct consequences of climate-related events, which may affect factories, infrastructure, collateral and supply chains.

Transition risk arises from the economic adjustment toward a lower-carbon economy, including regulatory changes, technological developments, carbon costs and changes in consumer or investor behaviour.

Law 7/2021 specifically requires covered credit institutions to assess climate-related financial risks, including risks arising from the transition toward a sustainable economy.

For industrial banks, transition risk may therefore become part of ordinary financial risk management rather than a separate corporate-social-responsibility exercise.

22. Supervisory Dimension

The modern framework can be represented as:

Environmental policy

↓

Industrial transition

↓

Need for capital

↓

Banks and capital markets

↓

Climate-risk assessment

↓

Prudential supervision

↓

Financial stability

Article 33 of Law 7/2021 reinforces this connection by requiring Spanish financial authorities to evaluate climate-related systemic financial risks.

23. Practical Example

Assume a Spanish steel manufacturer wants €500 million to convert part of its production system to lower-emission technology.

A bank cannot simply ask:

“Is this project green?”

It must also ask:

Credit: Can the company repay €500 million?

Technology: Will the new technology operate commercially?

Climate: Will the investment materially reduce transition exposure?

Regulation: Could environmental, energy or carbon rules change?

Competition: Does government financial assistance comply with EU State-aid requirements?

Disclosure: What sustainability information must the bank and borrower provide?

Prudential: How does the exposure affect the bank's risk profile and capital position?

This example shows why green industrial banking sits at the intersection of environmental law, banking law, industrial policy and EU economic law.

24. Importance of the Case Law

The cases discussed above collectively establish several useful principles rather than one single doctrine of “green industrial banking”:

1. Environmental objectives remain subject to EU law.
2. Government financial advantages can raise State-aid questions.
3. Renewable-energy investments remain exposed to regulatory and taxation risks.
4. Changes in public-support regimes can materially affect investment economics.
5. Banks must continue ordinary credit and prudential analysis for green projects.
6. Climate transition itself can generate financial risks that banking regulation increasingly requires institutions to identify and manage.

25. Conclusion

Banking Law and Green Industrial Policy Banking in Spain describes a developing legal framework through which finance supports Spain's transition toward cleaner industrial production while remaining subject to banking supervision, financial-stability requirements, environmental law and EU economic law.

The most important Spanish statutory connection is Law 7/2021 on Climate Change and Energy Transition. Article 32 brings climate-related financial risk directly into the framework applicable to covered credit institutions and requires portfolio decarbonisation objectives, while Article 33 establishes broader assessment of climate risks to Spain's financial system.

At the same time, green industrial policy does not replace traditional banking principles. Banks must still examine solvency, credit quality, collateral, capital, liquidity and regulatory risk. The Santander State-aid litigation and Spain's extensive renewable-energy cases and arbitrations further demonstrate that green industrial finance operates within wider rules concerning State aid, taxation, regulatory change, investment protection and EU law.

The resulting model can be summarized as:

Spanish industrial policy + climate legislation + EU sustainable-finance law + public development finance + private bank lending + prudential supervision = Spain's legal framework for green industrial banking.
