Lists of international environmental treaties, conventions, and other agreements with links to text, membership, performance data,
secretariat, and summary statistics.
Over 1100 multilaterals, 1500 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

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.
View Performance Data
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.
View Coded Agreements
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.

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.
