Bridging the gap between circular economy and climate change mitigation policies through eco-innovations and Quintuple Helix Model

Climate change represents an increasing threat to society and demands collaborative actions for changing technologies, production methods, and consumption. The concept of Circular Economy (CE) emerged aiming to increase the resource use efficiency and minimize resource inputs, waste and emissions generation. However, the contribution of CE eco-innovations to climate change mitigation goals, pushed by the Quintuple Helix Model (QHM) actors, is still unknown. This analytical review intends to fulfil this gap by investigating the main elements of the QHM that contribute to CE eco-innovations, namely companies, government, society, academia, and the natural environment. An analytical framework and theoretical propositions for future research are proposed. Eco-innovation technologies from energy, waste, transportation, construction and manufacturing sectors are discussed. Practical recommendations and implications for policymakers associated with CE and climate change policies and their interrelationship in terms of eco-innovations are also provided.
