Global environmental regulation of offshore energy production: Searching for legal standards in ocean governance

Abstract

The international environmental regulation of all types of energy generation activities at sea is first and foremost anchored to the United Nations Convention on the Law of the Sea (UNCLOS). However, both at the global and regional levels, UNCLOS is complemented by an array of evolving environmental agreements. These normative developments can put flesh on the bare bones of the general (due diligence) obligation of States to protect the marine environment with regard to offshore energy activities. Parallel to binding obligations under environmental agreements, there are a variety of non‐binding instruments, which can also play a key role in enriching the content of prevention obligations. Depending on their source, their form and the procedure by which they are adopted, these non‐binding pronouncements may become legally relevant as interpretative guidance or standard of proof that a State has exercised due diligence. In this context, the article posits that synergies among environmental instruments and the interaction of non‐binding instruments with binding rules of international law can fill the current legal gaps and strengthen the international legal standards for the regulation of this environmentally sensitive sector.

The Development of Floating Nuclear Power Platforms: Special Marine Environmental Risks, Existing Regulatory Dilemmas, and Potential Solutions

“…Hence, to prevent the operation of FNPPs from harming the marine environment, the deployment state should implement an environmental impact assessment for FNPP deployment. The current international conventions involving FNPPs' marine environmental impact assessment can be divided into the following four main categories: (1) nuclear safety conventions; (2) UNCLOS; (3) conventions aiming to address pollution from ships; and (4) conventions concerning environmental impact assessment of transboundary harm [69]. However, under the existing international regulatory framework, FPNP-related marine environmental impact assessments may face difficulties in practical implementation.…”

Legal and Political Barriers and Enablers to the Deployment of Marine Renewable Energy

“…Networks such as OES and European Energy Research Alliance (EERA) have also been playing an important role in the advancement of the sector. Additionally, the international environmental regulation of all types of energy generation activities at sea is first and foremost anchored to the United Nations Convention on the Law of the Sea (UNCLOS) [38]. This establishes rules governing all uses of the world's oceans and seas including their resources.…”

A review on development of offshore wind energy conversion system

“…The following is a brief description: Impact on marine ecological environment: The deployment of offshore wind power is rapidly expanding globally. It is necessary to increase the research on the impact of wind farms on the ecological environment 123,124 . Studies have shown that offshore wind farms and their associated erosion protection have the ability to provide a certain amount of habitat through installation.…”
