The Book takes the approach of a critique of the prevailing international environmental law-making processes and their systemic shortcomings. It aims to partly redesign the current international environmental law-making system in order to promote further legislation and more effectively protect the natural environment and public health.

Through case studies and doctrinal analyses, an array of initial questions guides the reader through a variety of factors influencing the development of International Environmental Law. After a historical analysis, commencing from the Platonic philosophy up to present, the Book holds that some of the most decisive factors that could create an optimized law-making framework include, among others: progressive voting processes, science-based secondary international environmental legislation, new procedural rules, that enhance the participation in the law-making process by both experts and the public and also review the implementation, compliance and validity of the science-base of the laws.

The international community should develop new law-making procedures that include expert opinion. Current scientific uncertainties can be resolved either by policy choices or by referring to the so-called "sound science." In formulating a new framework for environmental lawmaking processes, it is essential to re-shape the rules of procedure, so that experts have greater participation in those, in order to improve the quality of International Environmental Law faster than the traditional processes that mainly embrace political priorities generated by the States. Science serves as one of the main tools that will create the next generation of International Environmental Law and help the world transition to a smart, inclusive, sustainable future.
