Balancing Growth and Sustainability: The Impact of International Trade Law on the Environment

Abstract

The rapid expansion of international trade since the mid twentieth century has been a key driver of global economic growth. At the same time, this expansion has intensified environmental degradation, giving rise to complex legal and policy challenges at the intersection of trade liberalisation and environmental protection. This paper critically examines how international trade law, particularly under the framework of the General Agreement on Tariffs and Trade and the World Trade Organization, impacts environmental governance and sustainable development. It analyses the inherent tension between the objectives of free trade and the need for environmental conservation, focusing on the role of exceptions such as Article XX of GATT and the evolving jurisprudence of the WTO dispute settlement mechanism. The study explores the growing relevance of Multilateral Environmental Agreements and their interaction with trade obligations, highlighting how inconsistencies and enforcement gaps often undermine environmental objectives. Through an examination of landmark disputes and unilateral trade measures adopted for environmental protection, the paper evaluates whether existing legal frameworks effectively balance economic growth with ecological sustainability. Special attention is given to issues such as resource exploitation, hazardous waste trade, eco labelling, and process based trade restrictions. The research adopts a doctrinal and analytical approach, drawing from international treaties, case law, and scholarly literature to assess the adequacy of current mechanisms. It argues that while international trade law has gradually acknowledged environmental concerns, significant structural and institutional limitations remain. The paper concludes by emphasising the need for greater coherence between trade and environmental regimes, stronger enforcement of environmental commitments, and reforms aimed at integrating sustainable development as a central objective of global trade governance.
