The world is facing dramatic challenges related to environmental sustainability at an accelerating pace. In this context, the field of economic geography (EG) has been playing an important role in understanding both the socioeconomic and technological dimensions of these challenges, as it deals with a variety of complementary notions and perspectives. Departing from this lens, our aim is to explore a conceptual framework that can help us to understand environmental changes relating to multi-dimensional territorial development, notably in economic contexts where inequality is high, and stratification based on hierarchies regulate social and economic life. Based on the territory concept, we propose the original notion of a hierarchical regional innovation system (HRIS) that emphasises the pervasive role of hierarchies (powers) in regional innovation systems and illustrate its value with evidence and case studies from extant literature on sustainability transitions. The HRIS can help us understand and promote development paths considering the contribution of inclusive eco-innovations (another original conceptual amalgam). Through some empirical cases from other studies in low-carbon transitions, we show the application of the HRIS (and inclusive eco-innovation) framework. In conclusion, we provide incentives to explore new regional innovation systems, alongside the HRIS, adapted to different regions worldwide and centred on the inclusiveness of people and places.}
