Editing Triple bottom line (section)

==Subsequent development==
{{norefs|section|date=January 2024}}
Following the initial publication of the triple bottom line concept, students and practitioners have sought greater detail in how the pillars can be evaluated. The ''people'' concept, for example, can be viewed into three dimensions – organisational needs, individual needs, and community issues.

Equally, ''profit'' is a function of both a healthy sales stream, which needs a high focus on customer service, coupled with the adoption of a strategy to develop new customers to replace those that die away, and ''planet'' can be divided into a multitude of subdivisions, although [[Waste hierarchy|reduce, reuse and recycle]] is a succinct way of steering through this division.

The initial understanding is now supplanted by thinking beyond TBL: added to the TBL concept of economics, ethics and environment is the idea of thinking of the environment as a mantel that the other pillars hold up, and add to  Economics and Ethics, the notions of Energy, and Health or the 4 E's.
