Who is credited with coining the term "Triple Bottom Line"?

The term "Triple Bottom Line" was coined by John Elkington in the 1990s. This concept emphasizes the importance of three key dimensions of sustainability: social, environmental, and economic. By advocating for these three 'bottom lines,' Elkington sought to encourage businesses to expand their focus beyond just financial profits to include their impact on people and the planet. The model is widely recognized and used to help organizations assess their sustainability performance and encourage responsible business practices.

The contributions of the other individuals mentioned are significant in their respective fields, such as Dr. Karl-Henrik Robèrt's work on sustainability frameworks and Garrett Hardin's insights on environmental ethics, but it is Elkington who is specifically recognized for formulating the "Triple Bottom Line" concept.
