Environmental Performance Index ← Knowledge Base Where is the EPI from 2019/2017/2015/2013/etc. ? Can I assemble the releases of the EPI into a time series or panel dataset? Are there any EPI reports before the 2006 EPI? What is the difference between the Pilot 2002 EPI and the Pilot 2006 EPI? Regarding the EPI 2010. Could you clarify if the EPI scores can be, in fact, taken as a percentage (%). What is the reason that an EPI was established as a complement to the ESI?
