Coastal Communities Win Five-Year Battle Against Oil Giant's Seismic Survey Plans

Six coastal communities along South Africa’s Wild Coast waited five years for an answer. In mid-August 2026, the country’s Constitutional Court gave them one: Shell and Impact Africa cannot proceed with seismic surveys in the waters off their shores.

The ruling is the first climate case ever to reach South Africa’s highest court. It began in 2021 when those six communities, alongside NGOs and environmental justice organisations, challenged Shell’s exploration plans in a lower court. Their core argument was simple. They had not been consulted. The dispute moved through two courts before the Constitutional Court, the final arbiter under South African law, took it up and ruled against the exploration right entirely.

The court found serious flaws in the government’s decision to grant that right. Consultation with the coastal communities had been inadequate. Environmental and climate concerns had not been properly weighed. The seismic surveys themselves posed concrete risks: the powerful sound waves used to map underground rock formations raise concerns about harm to marine species and the ecosystems these communities depend on for their livelihoods, cultural practices and spiritual connections to the ocean.

What made this case historic was not only the threat to marine life. A central legal question was whether the climate impacts of new oil and gas exploration had been properly considered at all.

The court’s answer reshaped how South African law treats that question. Climate change, the court stated plainly, has moved from the margins to the centre of legal accountability. Section 24 of South Africa’s constitution guarantees everyone the right to an environment that is not harmful to their health or well-being, and requires that the environment be protected for present and future generations. Government cannot treat environmental protection as secondary to economic development. When deciding whether to approve a mine, oil project, road or any other development, it must weigh both benefits and harms to people and the environment, fairly, for those living today and those not yet born.

This reasoning carries particular weight in South Africa, where centuries of colonialism and apartheid created deep social and economic inequalities. New environmental damage compounds existing harm.

The judgment rests on five dimensions of justice. Procedural justice asks who gets a say. The court was direct: consultation is not an administrative box to tick. Public participation affirms dignity by giving affected people a seat at the table, recognising communities as participants rather than obstacles. Recognition justice asks whose identities, histories and relationships with nature count in government decisions. The coastal communities’ concerns involved livelihoods, cultural and spiritual practices, and connections with ancestors and the ocean. The court placed these within the longer history of dispossession affecting those communities.

Distributive justice asks who receives the benefits of development and who bears its costs. The court questioned assumptions that all oil and gas projects create jobs and pressed on who actually receives those jobs. Its words were unambiguous: “Investment without benefit to those who are most vulnerable and most affected is not in the public interest.” Inter-generational justice asks what today’s decisions mean for people not yet born. The court connected sustainable development and international climate obligations to the foreseeable effects of emissions on future generations. The judgment also creates space for thinking about justice beyond humans, inviting a broader understanding that includes ecosystems and other species.

Meanwhile, the court grounded its reasoning in international climate law. It noted that climate change transcends borders, with diffuse causes and uneven consequences requiring inherently international governance. Decisions made in South Africa contribute to climate impacts elsewhere, just as South Africa is affected by emissions from other countries. The court examined recent climate advisory opinions from the International Court of Justice, the International Tribunal for the Law of the Sea and the Inter-American Court of Human Rights. Those opinions establish that governments carry legal duties to prevent serious environmental harm caused by climate change. Citing the International Court of Justice’s 2025 climate advisory opinion specifically, the court stated that South Africa must prevent significant environmental harm, exercise due diligence and consider the foreseeable effects of emissions on present and future generations.

The judgment sets a precedent that connects South African constitutional law to a growing global body of climate law focused on legal accountability, human rights and justice. The harder question now is how future governments will weigh those obligations when the next exploration right lands on their desk.
