This thesis examines approaches consultants use to assist organizational leaders in moving strategically towards sustainability. The Framework for Strategic Sustainable Development (FSSD), is examined to understand how one can overcome and address the complex challenges that consultants face in assisting leaders to develop appropriate leadership skills and sustainability knowledge that will allow them to lead their organizations strategically towards sustainability. Two consulting firms located in London are reviewed. From this research, an ideal way of using the FSSD called the Strategic Leadership Training Framework (SLTF) is proposed as a tool to guide and supplement current approaches used by consulting firms to improve their leadership training programs. A gap analysis compares the SLTF and the current approaches used by consultants. The SLTF can be used as a tool to assist consultants to find the gaps between the approaches they use and the SLTF. Finally, emotional intelligence and a definition of sustainability are found to be a key factor for a leader to be successful when moving their organization strategically towards sustainability.
