This policy brief examines the lack of gender diversity in international investment and trade dispute resolution in light of Sustainable Development Goal (SDG) 5. The primary objective of the brief is to link SDG 5 with the imperative of diversifying international adjudication bodies in the fields of trade and investment. The brief demonstrates that women continue to be under-represented as adjudicators in the fields of investment and trade, and proposes steps necessary to address persistent under-representation. In particular, the brief argues that further empirical research in these fields and a targeted gender strategy are necessary to achieve meaningful progress. In its analysis, the brief will focus on the investor-state tribunals under the framework of the International Centre for Settlement of Investment Disputes and the World Trade Organization panels.
