Striving for sustainability is an important task for governments and non-governmental organizations as well as business and civil society actors. It is an ongoing process that calls for a new mindset and new methods to succeed. Transition management is a multilevel mode of governance that helps societies incrementally transform their activities in order to achieve necessary sustainability levels. The process towards sustainability is accelerated with the aid of intermediaries. In this chapter, we discuss proactive law, a concept which encompasses enabling regulation and sustainability schemes, as well as proactive competences to provide feasible building blocks for transition management in this process. A special reference is made to the textile industry and to Finland–India trade.
