This glossary has been developed to establish a shared conceptual foundation for all stakeholders operating in the fields of impact investing and the impact economy.

Impact investing, impact measurement and management, outcomes-based financing, and related concepts—which are increasingly used across finance, public policy, entrepreneurship, and social impact—are explained with reference to international frameworks while taking the Turkish context into account.

The aim is to create a consistent terminology across disciplines, reduce conceptual ambiguity encountered in practice, and support the wider adoption of impact-oriented approaches.
