The document presents the results of an environmental integration index assessment conducted in 6 Eastern Partnership countries in 2011-2012. It finds that Belarus has the best environmental situation overall, followed by Georgia and Moldova, while Ukraine has the worst. Key findings include: Belarus performs best on resource efficiency and environmental indicators; Ukraine lags due to heavy industry and conventional agriculture from the Soviet era; and all countries still lag the EU on areas like resource efficiency and environmental performance. Issues remain around strengthening administrative structures, environmental policy integration, access to information, and compliance with international agreements.
