From Market Shield to Ocean Stewardship: Rethinking EU Trade Remedies and Subsidy Control in the Blue Economy

Kolawole Afuwape^[1]*

Abstract

This paper reconsiders the trade remedies and subsidy control regimes of the European Union (EU) through the lens of “ocean stewardship”. It claims the EU's economic instruments exhibit a profound normative shift from the role of shield for defensive market regulation to sustainability governance in a proactive form. Historically the function of trade remedies and state aid disciplines has been to provide a shield for market stability, with competitive neutrality and counteracting unfair behaviour at the cornerstone of their objectives. However, under the developing framework of the European Green Deal, the Blue Economy Strategy, and the Trade and Sustainable Development (TSD) agenda, the emphasis of these instruments, or their application, has increasingly pivoted toward ecological responsibility and conservation of the oceans. This study contextualizes the EU trade and subsidy control regimes within a broader regime of normative power, where fairness in economics, environmental integrity, and governance of the ocean is constitutive rather than separate policy arenas. This normative reassessment of the regimes presents a unique instance of “sustainable market governance” and positions the EU as the global standard setter to promote climate justice and protect the oceans through trade regulation. However, this paper also questions the possible tensions of this approach and highlights the risks of green protectionism, extraterritoriality, and fragmentation between trade and environmental regimes. It notes that the EU's legitimacy as a leader depends on developing a coherent, transparent, and collaborative governance approach that balances competitiveness and stewardship while embedding sustainability into the principles of international economic order. Ultimately, the paper develops a critical vision of how trade defence and subsidy control, once vehicles of market insulation, can become regulatory conduits for ocean sustainability and global environmental governance.

1. INTRODUCTION

The trade remedies and subsidy control regimes of the European Union have traditionally been market protection tools, which are meant to protect the domestic industries against unfair competition by use of anti-dumping duties, countervailing duties, and safeguard actions.^[2] These measures result in fair competition and integrity on the market and are codified in Council Regulation (EU) 2016/1036 (Anti-Dumping) and Council Regulation (EU) 2016/1037 (Countervailing Measures) and are based on the WTO Anti-Dumping and SCM Agreements.^[3] In a similar vein, subsidy control, which is regulated by Articles 107-109 TFEU, but is now enhanced by the EU Foreign Subsidy Regulation (2022), also does not allow the distorting financial contribution of subsidies to be made against the Single Market.^[4]

This traditional economic structure has been changed with the recent developments in international environmental law and EU policy. Fisheries, aquaculture, shipping, offshore renewable energy, and marine biotechnology have become a strategic sector at the interface of economic growth, ecological stewardship, and global competitiveness, and are known as the blue economy.^[5] Sustainability aims are increasingly being pursued in EU law in terms of trade remedies and subsidy control, in commitments to the United Nations Convention on the Laws of the Sea (UNCLOS), the Paris Agreement, and the Convention on Biological Diversity, and the 2022 WTO Fisheries Subsidies Agreement, which in effect forbids subsidies that lead to overfishing in overexploited stocks.^[6] The convergence poses an underlying question: how can the EU integrate market protection and sustainability requirements in managing the blue economy? The doctrinal and operational tension is the one. The trade remedies and subsidy controls would have to navigate between the legal systems of the EU internal market, the WTO commitments, and the international environmental standards and targets, and encourage sustainable economic operations in ocean-based sectors.

An examination of the problem exposes the difficulties as well as opportunities. The EU law should be doctrinally aligned to protect the market and the environment, and sustainable and internationally accountable, and operationally, it needs to have a strong verification and monitoring system. Examples of fisheries subsidies, shipping decarbonization, and offshore renewable energy case studies show the empirical challenges of making trade remedies and subsidy control compatible with ecological requirements.

The system of the trade law of the EU is experiencing a paradigm shift: the giving of tools of normative leadership in ocean stewardship is replacing the instruments aimed exclusively at economic protection. With the inclusion of sustainability in trade remedies and subsidy disciplines, the EU is taking a step to prove that it can find ways to harmonize economic, environmental, and legal requirements and promote a consistent and proactive view of the blue economy.^[7] This background makes the current research the basis of the critical analysis of the doctrinal, practical, and policy aspects of harmonizing EU trade and subsidy law and the marine sustainability goals.

The main argument of this paper is that the EU’s conventional trade remedies and subsidy control mechanisms originally created as market protectors should be recalibrated to promote ocean stewardship to fit the emerging blue economy’s environmental, economic, and social objectives. The paper argues that the EU's current trade tools, including anti-dumping, countervailing duties, and state aid, stem from historical, industrial-based approaches that emphasize competitive neutrality and domestic market protection. However, they now exist in a changed global environment where marine resources, sustainable fisheries, and ocean-based industries are central priorities for a resilient EU green Deal and global climate targets.

The paper posits that applying traditional market adjustment tools to ocean-based industries without environmental and sustainability norms will sustain resource exploitation and create or sustain a carbon-intensive economy. Thus, the shift away from a "market shield" system and toward an "ocean stewardship" system needs to occur. This means collaborating blue economy outcomes such as marine biodiversity conservation, low-carbon transformations, and socially-just coastal communities within the EU's trade and subsidy governance.

The paper also argues that reconceiving EU trade assistance from a sustainability perspective demands three mutually supportive transformations: (1) redefining injury and benefit in trade law to take on ecological and social externalities; (2) introducing blue sustainability indicators into state aid and subsidy assessments; and (3) strengthening coherence between EU trade law, environmental law, and international ocean governance frameworks such as UNCLOS, WTO Fisheries Subsidies Agreement, and in relation to the European Green Deal.

1. SUBSTANTIVE AND NORMATIVE ANALYSIS

At its essence, this paper makes the case that the EU trade defence and trade policy instruments (for example, dumping duties, countervailing measures, and subsidies) may be transformed from a means of protectionism to a means of environmental stewardship.^[8] Historically they have primarily focused on protecting EU industry from an injury perspective of unfair competition or distortions of markets. In a blue economy context, which includes ocean-based industries and the sustainability agenda, they can be adjusted to internalize environmental and social costs.

From a sustainability perspective this rethinking fundamentally challenges how we define and think of “injury,” “benefit,” and “public interest” are perceived and defined in trade law. Instead of just viewing examples of environmental degradation, over-fishing, carbon emissions, and loss of marine biodiversity as injury with economic consequences. Thus, sustainable practices such as low-carbon innovation, circular marine production, and conservation-based entrepreneurship, that warrant protection and incentivizing. Moving away from sanctions for injurious instabilities, this normative categorization would transform trade remedies into policy mechanisms that incentivize and value sustainability.

The EU’s policy architecture is changing, driven by the European Green Deal, the Blue Economy Strategy, and recent reforms to state aid and carbon border adjustment measures.^[9] These developments demonstrate how trade and environmental law can come together. The EU has shown, for example, that trade defence instruments can be used to support systemic ecological transition, not just as a barrier to trade liberalization, by embedding sustainability criteria into subsidy control^[10] (e.g., reducing harmful fisheries subsidies while promoting green technologies).

TRADE REMEDIES AND SUBSIDY CONTROL IN EU AND WTO LAW

Overview and scope

The core of a classical confrontation in international economic law is a wish to guarantee the integrity of the market and a level playing field, and the sovereign freedom of states to seek industrial, social, or environmental policy goals using fiscal measures.^[11] This tension has, since the late twentieth century, been made complex by the global sustainability agenda. Ocean health, marine biodiversity, and the so-called blue economy form new conditions, where subsidies and remedies are not only economic tools, but also tools with far-reaching effects on the environment.^[12] The legal problem is thus promotional (how to interpret/adjust EU, WTO, and treaty text) and implemented.^[13]

History and purposes of EU trade-defence instruments.

The EU trade remedies were written to apply in the external relations of the Union. GATT/WTO provisions on unfair trade.^[14] The Anti-Dumping Agreement is a realization of Article VI GATT and establishes procedures and substantive tests on anti-dumping duties; the SCM (Subsidies and Countervailing Measures) Agreement is a regulation of subsidies and countervailing actions against them.^[15] The WTO disciplines are operationalized at the EU level through Union Regulations, where the principal regulation is Council Regulation (EU) 2016/1036 on protection against dumped imports and Council Regulation (EU) 2016/1037 on protection against subsidized imports provide the formulas of remedies as well as the procedures and the evidentiary tests of the investigations to be conducted by the Commission and Member States.^[16]

This study reconceptualizes the EU trade remedies, and state aid rule through this environmental–economic connection. Historically, these tools and measures were meant to provide a safety net for domestic sectors from unfair competitive practices driven by simply commercials. However, the EU’s principle of integration and the site more broadly of the Green Deal requires just this realignment: where trade and subsidy governance internalizes environmental costs and positively supports marine sustainability.^[17] The EU's ban on harmful fisheries subsidies and conditional approval on green state aid have signaled an effort to shift a focus from a strictly economic objective to a more ecological intention via the state's own Guidelines on State Aid for Climate, Environmental Protection, and Energy.^[18] Trade remedies can similarly be aligned with sustainability criteria or consider that environmental degradation and/or depletion of resources are essentially forms of 'unfair advantage', therefore expanding the notion of 'injury' to include ecological injury.^[19]

Goals and dogmatic restrictions

The three aspects of the objectives laid down in the canons are (i) to discourage and correct harmful, unfair competition, (ii) to maintain the integrity of the internal market, and (iii) to implement measures in a manner that is WTO-consistent (i.e., proportionate, grounded in evidence, non-discriminatory). The tools of the EU are thus a complex of technical economic tests (dumping margins, injury causation, subsidy benefit) and procedural safeguards, which should survive the challenges of WTO dispute settlement.^[20] Ideally, the EU's trade remedy regime plays a distributive (sheltering domestic industry) and normative (implementing fair trade) role.^[21]

WTO subsidy and fisheries disciplines (such as the 2022 Fisheries Subsidies Agreement)

According to the WTO SCM Agreement, a subsidy is governmental financial aid that provides a benefit (Article 1) and subsidies (prohibited, actionable, specific).^[22] It specifies the remedial instruments one can use to cure Members (countervailing duties, consultations, and dispute settlement) and provides restrictions as to how much government assistance could be used to prevent trade-distorting outcomes.^[23] Thus, the Agreement is the main multilateral tool that limits the use of subsidies by states in such a way that it distorts international trade.

Article XX jurisdiction space and environmental dimensions.

General exceptions of WTO (Article XX GATT), more so, in sub-paragraph (g) on conservation of exhaustible natural resources, have historically offered a legal loophole to Members to be able to justify otherwise WTO inconsistent environmental action.^[24] Appellate Body and panels (e.g., Shrimp-Turtle, Brazil - Retreaded Tyres) have gone on to establish a jurisprudence that allows conservation-oriented measures provided they meet the chapeau and are not a masqueraded restriction.^[25] The present jurisprudence applies in cases in which trade remedies or subsidy regulations overlap with environmental objectives, and interventions aimed at protecting marine life can be justified by Article XX.

Critical commentary and Analysis.

Friction in doctrine SCM vs. TFEU/FSR.

One of the fundamental doctrinal conflicts is between the normative logic of the subsidy law of the WTO and the internal law of the EU. The SCM is concerned with trade distortion, remedies.^[26] Article 107 TFEU is concerned with intra-EU competition and compatibility. The FSR has now superimposed extraterritorial control that reaches the support of foreign states. This practically establishes three interactive regimes, including (i) the WTO multilateral constraints (including an express environmental Fisheries Agreement), (ii) the internal state-aid compatibility doctrine in the EU (capable of condoning the environmental purpose), and (iii) enforcement of the Commission against distorting foreign subsidies. It is legally complex to coordinate these regimes, particularly when a subsidy is promoted towards an environmental goal (e.g., benefits on offshore renewables).

Normative opportunity and legal risk.

The EU is especially well placed to internalize sustainability into its trade-defence policy. The CJEU jurisprudence has allowed the use of environmental considerations in compatibility tests^[27]; the Foreign Subsidies Regulation (FSR) has allowed the Commission to enforce distortive foreign support using the Fisheries Agreement of the WTO^[28]; and the sustainability-based subsidy discipline is multilaterally acceptable.^[29]

Trade remedies and subsidy control are ceasing to be merely an instrument of market defence, and are becoming an instrument of environmental control, as well as strategic industrial policy.^[30] The Fisheries Subsidies Agreement of the WTO institutionalizes the environmental turn of the multilateral level^[31]; the FSR of the EU and the case law that is emerging based on Article 107 TFEU operationalizes a unique European model that tries to bind the market integrity with sustainability.^[32] The doctrinal challenge, and the policy challenge, will be to come up with investigative, evidentiary, and remedial standards that are not only WTO-conformant but also strong enough to discourage harmful subsidies, as well as to encourage sustainable blue-economy practices without teetering on disguised protectionism. It is the balancing act that the EU could take.

The EU legal infrastructure builds on and, in some ways, goes beyond WTO norms by incorporating environmental principles in Articles 11 and 191 of the TFEU. EU measures for trade remedies, anti-dumping, anti-subsidy, and safeguard measures have typically reflected WTO standards but are now increasingly affected by the European Green Deal, EU Sustainable Trade Policy, and Blue Economy Strategy.^[33] State aid and subsidy control will also begin to incorporate sustainability conditions permitting environmentally brown subsidies and removing potentially harmful subsidies, especially in fisheries, maritime transport, and renewable marine energy.^[34] This sequence denotes the EU's shift from market protection to a mode of stewardship-oriented governance in trade.

1. THE BLUE ECONOMY AND MARINE CONSERVATION IN EU LAW
2. The meaning of the Blue Economy: Sectors and Scope.

The Blue economy includes the economic and international activities associated with the sea, oceans, and coastal areas, committed to the sustainable development of the area without interfering with marine ecosystems.^[35] This is conceptually applicable in both traditional industries of fisheries, shipping, and coastal tourism, and in new businesses, such as offshore renewable energy, marine biotechnology, and aquaculture, in the EU. These industries help in having economic growth, employment, and innovations in the coastal and marine areas.

1. EU Sustainability Obligations: Art. 3(5) and 21 TEU.

Article 3(5) of the Treaty on European Union (TEU) requires that the EU should strive to ensure the sustainable development of the Earth to enhance environmental protection and combat climate change.^[36] Article 21 TEU also encompasses this commitment, whereby the EU is established to be able to build relations with third nations and international organizations to enhance sustainable development and ensure the preservation of natural resources.^[37] These clauses form the foundation of the external activities of the EU, such as the maritime policies and international activities.

1. UNCLOS and International Obligations on Marine Biodiversity.

The UNCLOS is the main international law that regulates the utilization and protection of marine resources.^[38] It sets rules on how oceans and seas should be managed in a way that balances the rights of the coastal states and the requirement to collaborate globally. According to UNCLOS, the EU has undertaken international agreements to preserve marine biodiversity, such as the Convention on Biological Diversity and the Convention on International Trade in Endangered Species of Wild Fauna and Flora.^[39]

The Advocate General Opinion and Court Judgment

Within the framework of the Blue Economy and environmental conservation, the CJEU has dealt with the intersection of the two in several rulings.^[40] In other cases, involving state support of maritime industries, the Advocate General has suggested that such support should be in line with the EU environmental goals, which would not allow the economic activities to harm marine conservation. The Court has supported these views and stressed the notion that economic growth in the Blue Economy must be in line with the sustainability undertakings in the EU.^[41

Analysis and Commentary

The conceptual consistency between the Blue Economy and Marine Conservation in EU Law is found within the evolution of EU legal and policy frameworks that have transitioned from endorsing sectoral maritime growth to institutionalizing sustainability as a foundational principle of ocean governance. The Blue Economy, presented in the EU Blue Growth Strategy and reiterated under the European Green Deal, acknowledges the ocean as a lever of economic development by means of fisheries, shipping, aquaculture, coastal tourism and marine biotechnology. However, the EU law, particularly under TFEU Articles 11, 191, and 192, imposes the requirement that such a scheme of economic activity must respect and restore marine ecosystems.^[42] This paper enshrines the principles of sustainable development goals (SDG), precautions, and integration of environmental objectives. Therefore, a commitment to both economic productivity and ecological management establishes the normative basis which is to reposition EU trade remedies as a form of sustainability and not simply defence of the internal market.

1. TENSIONS BETWEEN MARKET PROTECTION AND OCEAN STEWARDSHIP

The changing dynamics between trade defence policies and environmental sustainability is a complex issue under international law and policy.^[43] Although, the Trade Defence Instruments (TDIs) are used to protect domestic industries against unfair competition, its use in the environmentally sensitive sectors may unintentionally run counter to global sustainability goals.^[44] This discussion explores these tensions and how market protection and ocean stewardship can be considered in the context of EU law, the agreement of the WTO, and the international conventions, including the UNCLOS.

• 1. Trade Defence Measures vs. Ecological Sustainability Goals.

Anti-dumping, anti-subsidy measures, and others are all TDIs that aim at protecting the EU industries against unfair trade practices.^[45] Though their use in other industries, such as fisheries, shipping, and offshore wind energy, can have unintended ecological effects. As an example, fishing capacity-enhancing subsidies could be against the goals of the WTO Agreement on Fisheries Subsidies, which aims at ending subsidies that lead to overfishing and overcapacity. Likewise, trade defence in the shipping sector will act as an obstacle to the decarbonization of maritime transport, which is contrary to the aims of the EU Green Deal.^[46]

• 1. The Peril of Regulatory Fragmentation: WTO, UNCLOS, and EU Law.

The presence of various legal regimes, such as the WTO, UNCLOS, and EU law, may contribute to the problem of fragmentation of regulations, making it difficult to implement consistent policies.^[47] Although, the UNCLOS offers a detailed approach to conservation of the ocean, its terms and conditions can conflict with WTO regulations, especially with subsidies and trade restrictions aspects.^[48] The EU internal policies, e.g., the Common Fisheries Policy, will have to navigate through these complexities to balance between the trade and environmental goals. The controversies that come because of such regulatory overlap drive the need to have combined strategies that harmonize trade interests in line with ocean stewardship. In the maritime industries regarding state aid, the Advocate General has given an opinion that the aid should support the environmental interests of the EU, so that the economic activities will not be against the marine conservation programmes.^[49] These views have been maintained by the Court, which strengthens the idea that economic growth must be in line with sustainability obligations.

This paper posits that EU trade remedies and subsidy control frameworks must be adapted to reduce, not amplify, this tension. By incorporating ecological considerations including carbon intensity, biodiversity implications, and sustainability standards into the measuring of “injury,” “public interest,” and “state aid eligibility,” the EU can convert tools of market protection into tools of ecological governance. For example, the EU Regulation on Foreign Subsidies Distorting the Internal Market and the Fisheries Subsidies Regulation illustrate how trade-related tools can satisfy competitiveness and sustainability aims, in effect enabling the ethos of stewardship in economic governance.

This shift requires a conceptual change in fairness in trade, that is, fairness is not simply the absence of a level playing field but the presence of environmental stewardship. This reframing neutralizes the perceived opposition of market protection and stewardship by arguing that sustainable competition, which is based on responsible sourcing and use of resources, is the only legitimate form of market protection in the Blue Economy. Nevertheless, this point also highlights a structural tension, because unilateral EU measures will not exist without friction if a multilateral trading system is a priority when environmental designations are secondary to trade liberalization. Consequentially, the EU must lead by example by facilitating a stewardship-based model of trade that reconciles internal ecological legitimacy and external economic legitimacy.

1. TOWARDS A COHERENT FRAMEWORK

The EU is in a dire situation on how to balance its established market protection tools with the need to ensure ecological sustainability. The mechanisms that regulate trade remedies and subsidy controls, the two pillars of EU economic policy, have traditionally focused on the protection of domestic industries.^[50] Nevertheless, the advent of the blue economy, combined with the global environmental demands, requires a paradigm shift. The concept of sustainability in trade remedy studies and harmonizing subsidy regulation and environmental state aid with the provisions of the WTO legal regime, and the EU legal regime, are all important as a way of attaining a sustainable, resilient, and a legal framework that is consistent.^[51]

• 1. The inclusion of the concept of Sustainability in the EU Trade Remedy Investigations.

The EU trade remedy procedures, such as anti-dumping, countervailing, and safeguard proceedings, typically concentrate on shielding local businesses against unfair competition.^[52] Nevertheless, where ecological effects are not considered, enforcing these instruments on such sectors as fisheries, shipping, and offshore renewable energy may compromise ecological goals.

Fisheries: Anti-subsidy policies have the side effect of encouraging overfishing by not considering the ecosystem effects. Trade protection and marine conservation can coexist by incorporating the sustainability criteria in investigations, evaluating the effects of the stock health, bycatch, and habitat.^[53]

Shipping/Offshore Energy: Trade remedies in maritime transport and offshore wind sectors need to evaluate emissions of greenhouse gases, effects of marine biodiversity, and constraints to renewable energy development.^[54] The trade investigation needs to incorporate environmental assessment frameworks, which could be established through compulsory environmental impact assessment (EIAs) or ecological sustainability scoring, so that protecting the markets does not involve a cost to ocean protection.

1. Balance Subsidy Control and Environmental State Aid with Green Industrial Policy.

The control of EU subsidies is regulated by the TFEU, state aid provisions, and sectoral provisions. In the past, subsidies were used to enhance the competitiveness of industries, at times contradicting environmental goals.^[55]

Environmental State Aid: The European Commission has already issued Guidelines on State Aid on Environmental Protection and Energy (EEAG), which offer guidelines on the way to promote sustainable industrial practices.^[56] By matching the trade subsidies with the principles of EEAG, we make sure that the subsidies will promote sustainable production and reduce the negative impact on marine ecosystems.

Green Industrial Policy: The offshore renewable energy, sustainable aquaculture, and marine biotechnology subsidies must balance economic growth and environmental protection.^[57] Coherence between trade policy and industrial development can be maintained using mechanisms like conditional aid, performance-based incentives, environmental compliance clauses, etc.

1. Coherence in policy and Dispute resolution: WTO-UNCLOS-EU interfaces.

WTO/UNCLOS/EU Law Coherence: WTO/UNCLOS/EU coherence has opportunities and challenges to its intersection:

The Agreement on Subsidies and Countervailing Measures (ASCM) and the Fisheries Subsidies Agreement disciplines in the WTO contain restrictions on harmful subsidies.^[58] WTO rules should be followed in EU measures such that environmental objectives are incorporated without causing any kind of disputes.

UNCLOS: regulates the application, protection, and biodiversity of marine resources. EU trade remedies and subsidies in the marine sectors should not violate the principles of the UNCLOS, like sustainable use and preservation of the marine ecosystems.

EU Law: EU’s legislations, such as the Common Fisheries Policy and the Green Deal, as well as state aid frameworks, are being encouraged to navigate the WTO commitments as well as those of the UNCLOS.^[59] The regulatory fragmentation threats can be addressed by providing systematic alignment of policies, equivalence of assessment standards, and advanced dispute resolution systems.

1. REIMAGINING EU NORMATIVE LEADERSHIP: TRADE, SUSTAINABILITY, AND OCEAN GOVERNANCE

Figure 2 illustrates Reimagining EU Normative Leadership: Trade, Sustainability, and Ocean Governance.

An attempt to refocus global economic governance around the concepts of ecological integrity, social responsibility, and marine sustainability. Traditionally, trade remedies and subsidy control instruments in the EU anti-dumping duties, countervailing measures, and state aid rules were principally designed as market shields to promote competitive neutrality and protect domestic industries against perceived unfair foreign practices.^[81] However, with environmental and ocean governance elevated to strategic significance under the European Green Deal, EU Blue Economy Strategy and Sustainable Trade Policy Review, etc., these instruments began to serve a dual normative purpose to protect fair play in the market and to advance sustainability objectives.^[82]

This reformulation is emblematic of the EU's own image of itself as a "normative power" in the global system, exercising influence not through coercion but through diffusion of values, standards, and regulatory models. By embedding sustainability, marine protection and climate neutrality into its trade and competition law regime, the EU is taking the logic of internal regulation to the global regulatory space for itself as a laboratory of integrated governance.^[83] This coherence is clearly illustrated in regulations like the Foreign Subsidies Regulation, which evaluates foreign government support not only on its distorting impact on competition but on broader sustainability effects^[84], and the State Aid Guidelines for Climate, Environmental Protection and Energy, which conditioned financial support on demonstrable green outcomes.^[85] Collectively, these tools represent an innovation of EU regulation; they are mobilizing economic instruments as tools of ecological governance. In the arena of ocean governance, this normative reorientation suggests trade and subsidy policies should not be neutral to environmental degradation, but should reward marine conservation, discourage harmful subsidies and support sustainable uses of ocean resources in a Blue Economy.

CONCLUSION

The changing attitude of the European Union towards trade remedies and subsidy control illustrates a paradigmatic change in traditionally protective market mechanisms to an ecological stewardship component of the blue economy. Environmentally, the anti-dumping, countervailing, and safeguard instruments used by EU trade defence are now able to include environmental and sustainability issues, meaning that the economic protection should not interfere with marine biodiversity, fisheries sustainability, or offshore energy industry development. At the same time, EU subsidy regimes are gradually setting the rules of such kinds of financial support in such a manner that adherence to environmental goals is obligatory, maintaining a balance between industrial competitiveness and environmental requirements.

Although the issues of enforceability remain (through incompatibility with WTO, inability to measure ecological impact, and internal opposition), the transformative potential is immense. The EU can be seen as a global leader in responsible economic governance by inserting the concept of sustainability into FTAs, trade remedies, and subsidy control, and aligning the internal EU law with those of the UNCLOS and WTO.

Prospective observations support the significance of harmonization, strict monitoring, and accountability systems to facilitate sustainability goals are coherently put in place. In the end, the EU model demonstrates that market protection and ocean stewardship should not be mutually exclusive; instead, it can be mutually reinforcing, developing a strong structure that will resist a blue economy and normative world leadership in the sea.
