From Exception to Promotion: Re-Thinking the Relationship between International Trade and Environmental Law tells a new, unconventional story of the nexus between international trade and environmental law - a story in which the keyword is synergy rather than conflict, and where the trade regime was always meant for something greater than simply trade liberalization. This ‘something greater’ was peace in the first half of the 20th century. Today, it is sustainable development, environmental protection, and social inclusion. Environmental protection is therefore neither antithetical to the overarching purpose of the trading system nor simply a ‘non-trade’ issue to be incorporated within the trade regime, but rather part of its very nature and purpose. By telling this ‘untold’ story of the nexus, this book intends to raise historical awareness and open a constructive discussion on the future of the trade regime and of international economic law governance at large.
