Definitions

What are International Environmental Agreements ?

The IEADB defines an international environmental agreement (IEA) as an intergovernmental document intended as legally binding with a primary stated purpose of preventing or managing human impacts on natural resources.

Defining "international"

Although "international" can have broader meanings, the IEADB narrowly defines international agreements as intergovernmental agreements. The IEADB includes only agreements to which governments of two or more states have (or are allowed to) become parties. It excludes instruments between single governments and non-governmental organizations (NGOs), between single governments and international organizations, and between or among corporations, NGOs, or international organizations.

Defining "environmental"

The IEADB defines agreements as environmental if they seek, as a primary purpose, to manage or prevent human impacts on natural resources; plant and animal species (including in agriculture); the atmosphere; oceans; rivers; lakes; terrestrial habitats; and other elements of the natural world that provide ecosystem services (Daily 1997). 

The definition intentionally errs in being too broad (assuming those with narrower definitions can more readily discard included agreements then identify excluded ones) while trying to avoid including agreements most scholars and practitioners would not classify as environmental.

Importantly, this definition does not consider the actual effect of a treaty. It might be the case that some IEAs included in the dataset have harmful consequences on environmental protection and other treaties not included in the IEADB positively contribute to environmental protection. A definition of IEAs based on their environmental effects would diverge significantly from common usage. It would also have the analytic drawback of requiring that agreement effects be identified before they can be categorized as environmental. If used literally, it would precludes analysis of why some environmental agreements fail (because those that have no environmental effects would be defined as not environmental). The more restrictive, purpose-based definition used here skirts these problems and allows analysis of how, if at all, agreements intended to address environmental degradation differ from those intended to address other topics of international concern. 

Agreements addressing human health; conflict; cultural preservation; trade; uses of oceans, lakes, and rivers; outer space, nuclear radiation, transportation, weather, labor, and similar issues were not included unless those agreements addressed environmental issues as a primary concern.

An agreement's "primary purpose" was operationalized by searching for terms corresponding to this conception in agreement titles, preambles, or articles specifically designating agreement goals [search terms delineated in various tables below].

Defining "agreements"

The IEADB considers any treaty, regardless of its designation, as a agreement. It includes agreements designated as conventions, accords, charters, understandings, acts, arrangements, protocols, and their non-English equivalents.

The 1969 Vienna Convention on the Law of Treaties' defines a treaty as "an international agreement concluded between States in written form and governed by international law" in which states express a "consent to be bound" [Articles 2(1)(a) and 11 through 17].

When the legally-binding nature of text is unclear, the IEADB considers reliable sources of opinion, such as a secretariat, UNEP, or published legal analysis. 

The IEADB provides a historical record of signed agreements. It is not limited to agreements in force, since it includes agreements that never entered into force and others that have been terminated. 

Amendments to agreements are considered as agreements for the purpose of the IEADB. 

The IEADB does not include action plans, agreed measures, codes of conduct, declarations, resolutions, and similar soft law instruments. It also excludes European Union directives because they are distinct in several important ways from other international agreements (Burns 2002; Burhenne and Jahnke 1993; Brown Weiss 1997).

inclusion

The variable "inclusion" in the dataset provides a three-letter code for each instrument listed. The first letter is either B (bilateral), M (multilateral), or O (others, such as transnational institutions). The second letter is either E (environmental), N (non-environmental), or U (uncertain). The third letter is either A (agreement) or N (non-agreement).

Key variables

Mitch-ID

Mitch IDs are unique identification numbers assigned to thousands of documents, including some that are excluded from the dataset because they do not fit the definition (to leave a trace for the reason of their exclusion). There is no particular order to the Mitch-ID. Related datasets use to the Mitch-IDs as a key to make these datasets interoperational with the IEADB. 

Bilateral (BEA) or multilateral (MEA) agreements

An agreement is considered as multilateral if it has three parties or more. 

Lineage 

A lineage is any set of legally-related agreements that are linked by the fact that they modify, replace, extend or otherwise constitute agreements that have a legal relationship to each other. The lineage concept is intended to help scholars and practitioners see the legal development of an issue area in ways that are not usually readily apparent. 

For example, the marine pollution (MARPOL) lineage includes the original 1954 OILPOL agreement; the 1962, 1969, and 1971 amendments to that agreement; the 1973 MARPOL agreement that replaced the 1954 agreement; the 1978 Protocol to the MARPOL agreement; and numerous amendments of the 1973/78 MARPOL agreement as well as several separate related conventions. 

The Sequence Number for a lineage is a numbering system devised to show the legal sequence of agreements, using the following conventions:

  • Hundreds are used to designate agreements (e.g., 100.00 is the first agreement in a lineage, 200.00 is the second agreement in a lineage, 300.00 is the third agreement in a lineage).
  • Units are used to designate protocols (e.g., 601.00 is the first protocol to the sixth agreement in a lineage, 307.00 is the seventh protocol to the third agreement in a lineage). 
  • Decimals are used to designate amendments (e.g., 103.01 is the first amendment to the third protocol of the first agreement in a lineage, 205.04 is the fourth amendment to the fifth protocol of the second agreement in a lineage).

Freshwater resources

This category and subcategories seeks to capture agreements related to regulation of lakes and rivers. In most cases, agreements to protect freshwater resources are designated by the name of the relevant water body with little specificity in the title as to what environmental aspect is being protected. I have assumed the word "protection" of a river or lake involves environmental protection. In other cases, however, I have used the preamble in an attempt to distinguish environmental protection of freshwater resources from those agreements respecting rivers or lakes that only target navigation.
