Over time, the range of sustainability objectives has developed from relatively simple issues of environmental protection to encompass international and national social, economic and ecological issues. A closer examination of the evolving range of sustainability issues, and the involved changes within governments and businesses, reveals a complex process. Related to this complexity are the benefits of a collaborative stakeholder approach in achieving objectives of sustainable development. The aim of this study is investigating these change processes in the public and the private sector and analysing the potential benefits of a collaborative stakeholder approach.
