Institute for Free Enterprise (IFE) — Formerly Berlin Manhattan Institute
The Institute for Free Enterprise (IFE), which briefly went under the name Berlin Manhattan Institute for Free Enterprise from 2010 until 2012, is a registered charity in Berlin. 
According to the Institute for Free Enterprise, Germany's “vast potential can be unlocked … with the right set of policies” including “Unhampered market forces, proper application of the rule of law, and sacrosanct civil liberties rather than centrally administered government planning.” 
According to an archived version of their website (Berlinmanhattan.org, no longer appears to be in operation), the Berlin Manhattan Institute described itself as “Germany's free market think tank and successor to the Institute for Free Enterprise (IUF).” It returned to become the Institute for Free Enterprise in 2012. The BMI “advocates policies that promote entrepreneurial initiative, creativity, innovation and competition.” 
The Institute for Free Enterprise and the Berlin Manhattan Institute have both regularly hosted conferences inviting climate change skeptics from across the world including representatives from the The Heartland Institute, European Institute for Climate and Energy (EIKE), Science and Public Policy Institute, and others.
