The typology framework is composed of four chapters: objective, scope, operations, and governance that are the main foundational elements of a sustainability initiative. Each chapter is broken down into differentiators, which are building blocks based on value neutral characteristics that can provide comprehensive assessments of the broad landscape of sustainability initiatives as well as facilitate differentiation between groupings of initiatives. The typology currently consists of 18 differentiators. For each differentiator, potential attributes are introduced and defined.
Two practical principles concerning the typology framework are important to bear in mind.
Although the typology is designed as a comprehensive framework, it necessarily comes with simplifications. In particular, there may be various interlinkages and interdependencies across chapters, differentiators, and attributes which the typology does not explicitly account for.
Potential attributes of a differentiator are not necessarily exclusive. For instance, the facilitation objective of a sustainability initiative could consist in providing at once guidance, tools, and capacity building, even though these are all captured by distinct attributes in the typology.
Figure 2.1 on the following page provides a graphical representation of the typology framework. The remainder of Section 2 lists and defines all chapters, differentiators, and attributes.
