In the 2010 environmental performance index (EPI) produced by researchers at Yale University, which benchmarks implementation of environmental policy against national governments’ goals, only three EU Member States figure among the top 10 (out of a total of 163) best performing countries.
Saskaņā ar vides raksturlielumu indeksu ( EPI — „environmental performance index”) 2010. gadā, ko izstrādāja Jeilas universitātes zinātnieki un ar kuru nosaka valstu valdību vides politikas jomā noteikto mērķu sasniegšanas sekmīgumu, starp labākajām 10 (no 163 valstīm) tikai trīs ir ES dalībvalstis.
