Marine Environmental Law Obligations.

Marine Environmental Law Obligations

Marine environmental law is the body of law aimed at protecting oceans, seas, and coastal ecosystems from pollution, overexploitation, and degradation. States, corporations, and individuals have legal obligations under both international conventions and domestic legislation. These obligations generally cover pollution prevention, sustainable use of marine resources, habitat protection, and liability for damages.

1. International Obligations

The primary sources include:

• United Nations Convention on the Law of the Sea (UNCLOS, 1982)
  Requires states to protect and preserve the marine environment, prevent pollution from land-based sources, ships, and seabed activities, and cooperate internationally.
• International Convention for the Prevention of Pollution from Ships (MARPOL, 1973/78)
  Obligates ships to minimize oil, chemical, and garbage pollution.
• Convention on Biological Diversity (CBD, 1992) and Convention on the Conservation of Migratory Species
  Require conservation of marine biodiversity and protection of endangered species.
• London Convention (1972)
  Regulates dumping of waste at sea.

Key Obligations under International Law:

1. Preventive Duty: Take measures to prevent marine pollution.
2. Due Diligence: Ensure activities under a state's jurisdiction do not harm other states' marine environments.
3. Environmental Impact Assessment (EIA): Assess potential environmental risks before maritime development projects.
4. Liability and Compensation: Parties causing marine damage may be liable for restoration costs.

2. Domestic Obligations

States implement international norms via domestic legislation. Examples include:

• Marine Pollution Acts (varies by country, e.g., the US Clean Water Act, UK Merchant Shipping Act)
  Obligate reporting, controlling discharges, and emergency response measures.
• Protected Areas Legislation
  Establish marine protected areas (MPAs) and restrict harmful activities.
• Fisheries Regulations
  Enforce sustainable harvesting and prevent overfishing.

3. Corporate and Individual Obligations

• Ships must comply with MARPOL regulations, including proper waste disposal and reporting.
• Oil and gas operators must conduct environmental risk assessments before offshore exploration.
• Fishing companies must adhere to sustainable quotas and gear restrictions.
• Coastal developers must follow EIA procedures and avoid habitat destruction.

• Holding: Operator and contractors liable under US environmental law for cleanup and damages.
• Principle: Corporate accountability, preventive measures, and liability for marine pollution.

g) The “Southern Pacific Islands Waste Dumping” Case (Australia, 1990s)

• Issue: Illegal dumping of industrial waste in the ocean.
• Holding: Government prosecution emphasized obligations under the London Convention.
• Principle: Prohibition and enforcement against marine dumping.

5. Key Takeaways

1. Marine environmental law imposes strict preventive and compensatory duties.
2. Obligations are both international (UNCLOS, MARPOL, CBD) and domestic.
