The document proposes a Capability Maturity Framework for Sustainable ICT developed by the Innovation Value Institute. It aims to help organizations assess and improve their maturity in sustainable ICT practices. The framework evaluates capabilities across nine building blocks including strategy, processes, people and culture, and governance. Assessments provide insight into an organization's strengths and challenges to develop sustainable ICT. Increasing maturity involves systematically improving each of the nine building blocks over multiple levels from ad hoc to optimized practices.
