The Access Initiative (TAI) has developed a unique methodology allowing users to assess implementation of several "access principles" as they relate to environmental decision-making - access to information, access to participation, access to justice, and capacity-building. Assessing Information, Participation and Justice for the Environment: A Guide contains the actual tools for this assessment, with accompanying instructional text. With the resources on this CD-ROM and web-based application, new TAI partners around the world will be able to score their countries' performance in providing access.
