Sustainability reporting is a vital tool to communicate an organisation’s sustainability performance to stakeholders. Sustainability reporting also allows an organisation to communicate its vision, goals and strategic plans. In order to be strategic towards sustainability, an organisation should have a vision of where it wants to go, and assess where it is today, so as to take the right initiatives towards its vision. This thesis focuses on how GRI sustainability reporting and strategic planning towards sustainability can be combined in an integrated process to help organisations move towards sustainability. The Integrated Process allows an organisation to gain a better understanding of its sustainability context; design resilient strategies in light of that context using a backcasting from Sustainability Principles approach; and report its sustainability performance and progress in bridging the gap towards sustainability, transparently to internal and external stakeholders.
