For sustainability, markets alone do not suffice – governance is also needed. Governance is a broader notion than government. Both words can be traced back to the Greek word ‘kyberbes’, which means a ‘helmsman’, whose skill involves knowing where to go, making decisions about a course to get there, and taking the actions needed to stay on that course. Government refers to the state, which has the authority to take decisions on behalf of the entire community. Governance refers also to the myriad other organisations and institutions involved in steering society. In Part III we are going to look, in Chapter 10, at sustainable development as destination, the policy objectives intended to get society and economy there, and, in Chapter 11, at policy instruments for pursuing these objectives.
