I. Introduction

International environmental law is an ever-changing, constantly expanding, and intriguing topic for international legal research.  When decisions and collaborations occur between nations across international boundaries and treaties or agreements are made to cooperate for environmental concerns, disputes inevitably transpire because of trade implications for the respective nations, safety concerns and cleanliness of environmental resources among shared borders, or problems with enforcement mechanisms for liability under agreements or treaty provisions relating to the environment.  The vastness of this area of international law includes the environmental sub-issues of population, biodiversity, global climate change, ozone depletion, preserving the Antarctic regions, movement of toxic and hazardous substances, land or vessel-based pollution, dumping, conservation of marine living resources, trans-boundary air and water pollution, desertification, and nuclear damage, among others.  To begin research in international environmental law, a researcher should have a basic understanding of international law and authority: for example, knowledge of treaty research and an awareness of the types of international agreements and their effect in nations of the world as result of reservations, understandings, or declarations.  As noted in this research guide, the number of international environmental treaties is manageable by sub-topic, so identification of the appropriate sub-topic or category of international environmental law is essential to narrowly tailor research and avoid getting bogged down in the wealth of information.  Like many areas of international law, regulation and implementation of the treaty terms are at the national level.  Thus, some knowledge and research of foreign laws in the countries of focus for a research problem is necessary for thorough research and analysis.  This guide will provide an overview of the key terms, general starting points by sub-topic of international environmental law and correlating treaties and agreements, a summary of the essential websites and secondary sources for international environmental legal research, and an approach for researching the primary law of foreign jurisdictions for this topic.  Finally, an overview of the prominent international organizations and correlating documentation produced for international environmental law and blogs for current awareness in this field will be provided for a comprehensive overview.  For other specialized topics in international environmental law research, please consult the GlobaLex guides on International Marine Environmental Law by Arundhati Ashok Satkalmi, Kyoto Protocol by Deborah Paulus-Jagrič, Sustainable Development Law by Gary Yessin, and Transboundary Freshwater: Research Guide on Transboundary Freshwater Treaties and Other Resources by Barbara H. Bean.    


II. General Starting Points and Key Abbreviations

Like other areas of specialized international law, international environmental law follows the same sources and categories of law as primary authority under Article 38 of  the Statute of the I.C.J.  Those include treaties, custom, general principles recognized among nations, decisions, and other secondary authority such as the writings of prominent scholars in the field.  Therefore, a researcher should start with identifying the applicable treaties in force and analyzing those nations which are parties to the agreement.  After determining all applicable treaties based on the facts of the research question, then the researcher can uncover national laws, which might accordingly follow the treaty terms or deviate.  Because foreign legal research can be difficult, it is often wise to consult a comprehensive secondary source on the topic, such as a treatise or law journal article.  Before even approaching the treaties, though, it is helpful to decipher the tricky acronyms that emerge when studying international environmental law, especially in the context of the treaties and agreements.  Historically, the timeline of treaties that are often identified as monumental in the formation of international environmental law include: the Stockholm Conference (1972), UN Convention on the Law of the Sea (“UNCLOS”) (1982), World Conference on Environment and Development (1987), UN Conference on Environment and Development (1992), and the World Summit on Sustainable Development (2002).  A helpful overview of international environmental law is provided in International Environmental Law in a Nutshell by Lakshman D. Guruswamy (West 2003) for those researchers unfamiliar with this area of international law.  As discussed below, there are also many sub-categories of treaties based on the type of environmental concern or prevention of certain types of deterioration or liabilities for pollution.  Here are some of the most commonly-used abbreviations and acronyms for treaty research in international environmental law (however, keep in mind that it is not a comprehensive list):



III. Treaty Research

A. Sub-Topics for International Environmental Law

Because of the many possible sub-topics available for international environmental law, it is helpful to have a table of categories and correlating agreements.  The following table is a table of agreements and websites for research based on the eight sub-topics of hazardous waste, nuclear waste, ocean and marine sources, ozone and protection of the atmosphere, pollution, protection of species and wildlife, sustainable development, and trade and the environment.  When available, I have linked to sources of the original .pdf document available online.

B. Essential Indexes and Finding Aids for Treaty Research

There are numerous treaty indexes for historical U.S. treaties, as well as world treaty series.  In some instances, these treaty indexes are available in print and online.  For international environmental law, it is most helpful to consult indexes containing world treaties, such as the United Nations Treaty Series or the European Treaty Series, and other unique online collections of world treaties.  In the United States and depending on other jurisdictions for research, a researcher would also need to consult Treaties in Force, Treaty Actions, and the Department of State’s website for international agreements reported under the Case-Zablocki Act.  The following list of indexes and helpful online collections is not exhaustive, but includes comprehensive portals for research:



IV. Finding the National Laws of Foreign Nations

In addition to locating the appropriate treaties and agreements for research in international environmental law, a researcher then needs to uncover any national laws of the foreign nations involved in a research question.  Therefore, the following sources can help provide background information about the legal systems of countries of the world or links to the national laws of foreign nations.  The following list provides essential resources for uncovering national laws for international environmental law:



V.  Searching Library Catalogs and Finding Print Resources

Before researching primary law, such as treaties and agreements and laws of the nations of the world, researchers might also consult their library catalog to uncover helpful treatises, books, or nutshells and basic background texts to better understand this area of international law.  The following search terms and Library of Congress subject headings are successful when researching library catalogs:


Climatic Changes—Government Policy (Library of Congress)

Environmental Degradation—United States (Library of Congress)

Environmental Economics (Library of Congress)

Environmental Ethics (Library of Congress)

Environmental Impact Analysis (Library of Congress)

Environmental Law—Europe (Library of Congress)

Environmental Law, International (Library of Congress)

Environmental Law, International—Sources (Library of Congress)

Environmental Law, Periodicals (Library of Congress)

Environmental Management—International Cooperation (Library of Congress)

Environmental Policy (Library of Congress)

Environmental Protection (Library of Congress)

Global Warming –Law and legislation (Library of Congress)

Global Warming—Government Policy (Library of Congress)

Greenhouse gases—Law and legislation (Library of Congress)

International Relations—Environmental Aspects (Library of Congress)

Law of the Sea (Library of Congress)

Marine Resources Conservation—Environmental Aspects (Library of Congress)

Liability for Environmental Damages, European Union (Library of Congress)

Sustainable Development—(Country of Research) (Library of Congress)

United Nations Convention on Climate Change (Library of Congress)


In addition to the above categories, which are not comprehensive but give the researcher a head-start, it is useful to search terms in the title of the international environmental agreement of focus or also search sub-topics of international environmental law.  To begin, a researcher could use terms from any of the sub-topics listed above in Section III.A: “Hazardous Waste,” “Nuclear Waste,” “Ocean and Marine Sources,” “Ozone and Protection of the Atmosphere,” “Pollution,” “Protection of Species and Wildlife,” “Sustainable Development,” and “Trade and the Environment.”  It would be essential, though, to brainstorm search terms that are relevant for the sub-topic of research and issues involved in the facts of the research problem.
