This article systematically evaluates whether, how, and to what extent twelve prominent forestry and fisheries certification schemes address human rights in their standards. In line with the broader cross-fertilization of the fields of international human rights and environmental law and policy, our results demonstrate that human rights norms and considerations – primarily Indigenous, labour, and procedural rights – are increasingly reflected in the rulemaking of these schemes. At the same time, our analysis also demonstrates the mixed and underwhelming performance of certification standards in protecting human rights norms, including those relating to women, children, racialized and ethnic minorities, persons with disabilities, Indigenous peoples, workers, 2SLGBTQIA+ communities, and peasants and rural peoples. Through descriptive statistics, we also show that levels of human rights adherence vary significantly across schemes and that standards developed in the forestry sector tend to outperform those for fisheries. Our methodology and results add a new dimension to efforts to assess the stringency, equity, and legitimacy of private authority in the environmental field.
