The quadruple and quintuple helix framework can be described in term s of the models of knowledge that it extends and by five subsystems
(helices) that it incorporates; in a quintuple helix-driven model, knowledge and know-how are created and transformed, and circulate as
inputs and outputs in a way that affects the natural environment. Socio-ecological interactions via the quadruple and quintuple helices
can be utilized to define opportunities for the knowledge society and knowledge economy, such as innovation to address sustainable development, including climate change.
