During the 1990s, 50% of the reduction of CO2 emissions occurred thanks to the restructuring of the East German economy following reunification (Eichhammer et al, 2001, Weidner and Mez, 2008). Inefficient heavy industries located in the new Ldnder collapsed, inducing a reduction by 44% of C02 emissions in that region (OECD, 2001). Outsourcing of manufacturing industries to eastern European countries as well as an increasing import penetration probably also contributed.
