In its flagship report, the German Advisory Council on Global Change (WBGU) elaborates explicitly on the fact that the technological potential for comprehensive decarbonisation is available, outlines business and financing models for the transition, and points out that the political instruments needed for a climatefriendly transformation are widely known. The council also describes how the requisite transformation encompasses profound changes to infrastructures, production processes, regulation systems and lifestyles, and extends to a new kind of interaction between politics, society, science and the economy. Various multilevel path dependencies and obstacles must be overcome. Furthermore, the transformation can only succeed if nation states put global cooperation mechanisms before their own shortterm oriented interests, in order to make a trend reversal, particularly as far as the global economy is concerned, towards climatefriendliness and sustainability possible. And not least, from a global perspective, this is also about issues of fairness – issues that need resolving.
