Residents of the Niger Delta have sued multinational oil and gas company Shell for environmental harm and human rights violations. Netherlands-based advocacy organisations support the affected residents in their endeavour, together with local civil society. Within this transnational justice alliance multiple ideas and narratives of the harm experienced and what should be done about it interact, through dynamic processes which have been conceptualised in social movement and human rights scholarship as travel, translation and transformation. What implications do these processes have for the environmental justice agenda of different stakeholders and their chances of achieving meaningful redress? And how can strategic transnational litigation contribute to, or hinder the kinds of conversations that are needed to transform the complex legacy of oil in the Niger Delta?
