The book investigates the impact of the initiatives which have emerged in the absence of a dedicated international agreement, including Reducing Emissions from Deforestation and Forest Degradation (REDD+) and forest certification, which are assessed in the wider context of the development of international environmental law. It also considers the role of regional forest agreements in the international protection of forests. It assesses the challenges to the effectiveness of international law governing forests, in particular the disparate nature of the law as it stands, and posits that the solution can be found in existing regional agreements. It argues that a more specific international treaty, consistent with the recent decisions of international courts on environmental protection and building on the experience of regional legal instruments, may offer an effective path forward.
