What is Triple Bottom Line Plus One (TBL+1).

The Triple Bottom Line was created by John Elkington in the late 1990’s. The three dimensions are
- The environment,
- Social & Cultural, and
- Economic.

At GS@RMIT we have added Governance, as the fourth significant dimension.

We call it The Triple Bottom Line Plus One (TBL+1).

The four dimensions of the TBL+1 have been developed into Doorways to Global Sustainability providing a range of tools for us to understand and take action on these often cutting edge issues. Doorways to Global Sustainability include concepts, theories and sometimes methodologies or practices. All of them indicate areas of change, which need to be understood and addressed from a corporate, government or civil society perspective.

This material is background information. It is geared to be practical and to help develop working models of global sustainability be they very small or very large.

This is a living site. It will evolve and grow over time. Because global sustainability is so new and so diverse it is necessary to focus on the most significant issues.

The “History of an Idea” and “Descriptions of Global Sustainability” have been collected from all sorts of sources. They provide insight into the forces, ideas and events around the world that have put Global Sustainability Institute stage in the 21st Century.
