The duty of states to prevent pollution highlights their active role in maintaining marine health. This obligation involves adopting legislative measures, enforcing regulations, and cooperating internationally to mitigate land-based and maritime sources of pollution. Such responsibilities reflect the shared nature of marine resources and the common interest in preserving them.

The principle of the common heritage of mankind underscores that the deep oceans and areas beyond national jurisdiction are a global element for humankind. It promotes equitable use, shared responsibilities, and the need for international cooperation in managing these resources sustainably. These core principles underpin the legal framework aimed at effective marine protection within public international law.

Sovereignty and Responsibility of Coastal States

Sovereignty of coastal states over their maritime zones grants them legal authority to regulate activities within their jurisdiction. This sovereignty is recognized under principles of international law and is fundamental to the protection of the marine environment within national waters.

However, sovereignty also entails responsibility for ensuring that their conduct does not harm the wider marine environment. Coastal states are obliged to prevent pollution and manage resources in a manner consistent with international commitments.

In fulfilling these obligations, coastal states must adhere to international legal frameworks, including treaties and conventions, which establish their duties. They are encouraged to enforce regulations effectively while cooperating with neighboring states to address transboundary marine issues.

Key responsibilities include:

• Managing pollution from land-based and sea-based sources, and
• Implementing marine conservation measures to protect biodiversity.
  This duality of sovereignty and responsibility emphasizes the importance of international cooperation in marine protection efforts.

Duty of States to Prevent Pollution

The duty of states to prevent pollution is a fundamental obligation under public international law that aims to safeguard the marine environment. States must take proactive measures to prevent pollutants from entering marine waters, ensuring the health of marine ecosystems.

This duty involves implementing national regulations consistent with international standards, monitoring pollution sources, and controlling activities that could cause harm. States are also responsible for ensuring that vessels operating within their jurisdiction comply with relevant pollution control laws.
