The Sustainability Toolkit has been developed to address the lack of available practical guidance on how to implement sustainability in an organization. In essence, the Toolkit integrates globallyrecognized approaches to sustainability and systems-based management (ISO 14001, OHSAS 18001, and ISO 26000). The basis for the system-based approach is the Plans-Do-Check-Act (PDCA) process which breaks down initiatives into smaller manageable steps and leads to continual improvement. By integrating a management system framework into the social responsibility guidance defined by ISO 26000, the Toolkit is a practical and flexible approach to sustainability implementation that is applicable to all sizes of organizations across various industry sectors. This project will validate the tool by testing the 13-step approach to sustainability integration within SMEs across various sectors.
