Domestic courts enjoy generous attention in international political and legal climate change literature. As a result of the reluctance of national governments to pursue climate protection measures, courts are called on to enforce international climate goals. This article assesses two domestic climate change cases (the Thabametsi Case and the Vienna Airport Case) in the light of Anthea Roberts’ functional understanding of the role of domestic courts in international law. It argues that domestic courts play a pivotal role in linking international obligations of conduct with national obligations of result. This role depends on domestic contexts and, therefore, requires a comparative approach.
