Although infrastructure in the transport and energy sector is highly relevant to society and economy and although global estimates show very high adaptation costs for infrastructure, the question of how utilities adapt to climate change has not been deeply investigated so far.The study analyses already taken efforts, future potentials and current problems concerning adaptation of utilities by applying a multi-method research design. It consists of a survey of German utilities, a series of stakeholder workshops with selected corporations, a qualitative analysis of the policy arena and a impact assessment. The first objective is to identify to what extent utilities have already started to adapt, and whether current activities are in an adequate range. Secondly, hypotheses about potential barriers to adaptation are evaluated.
