IEA Database Home

The IEADB website is constantly revised and updated. Current count of include MEAs, BEAs, etc. can be found here. The dataset also includes over 100,000 state "membership actions" (dates of signature, ratification, or entry into force; release notes here).  A major thanks to Jorg Balsiger and Lorris Germann of the University of Geneva who identified over 650 BEAs and have provided the foundation for the IEADB to become a comprehensive list of both bilateral and multilateral environmental agreements (for a list of BEAs by decade check here).

Downloads of various IEADB data are now available here or via these links

Agreement Lists

Lists of international environmental treaties, conventions, and other agreements with links to text, membership, performance data, secretariat, and summary statistics. Over 1300 multilaterals, 2200 bilaterals, and 250 "other". Grouped by Date, Subject, and "Lineage" of legally-related agreements (e.g., those related to the Montreal Protocol). "Other" includes environmental agreements between governments and international organizations or non-state actors, rather than 2 or more governments.
NEW: Membership links in agreement lists now provide year-by-year status reports, and the same information in Stata format for data analysis.

Performance Data

Datasets of over 150 environmental indicators (from secretariats or scholars) linked to the IEAs trying to improve them, for use in assessing the influence/effectiveness of IEAs, e.g., whale harvest (1910-2005)acid rain emissions (1980-2005); and emissions of ozone depleting substances (1986-2005). Use the Performance Data link or the "Data" links in each Agreement list.

Coded Agreements
Compare provisions among over 150 multilateral environmental agreements (MEAs) that the IEA Database Project has coded. For example: agreements having withdrawal clauses can be selected; the membership or entry-into-force provisions of numerous agreements can be compared; or the implementation mechanisms of a range of agreements can be systematically evaluated.

Relevant Literature
Currently under development, this component seeks to identify 5 to 10 books, articles, or chapters related to specific IEAs or lineages as "starting points" for students and scholars.

Linked Treaty Datasets and Data Archives
The IEA Project began in Fall 2011, to provide a means to archive datasets related to environmental treaties that can no longer be readily housed elsewhere.
