Technological innovation is essential to achieve simultaneously economic, environmental and social goals (i.e. the green growth). Indeed, many studies found that environmental innovation spurs overall innovation. However, this topic has not been investigated by taking into account the geographical context. Therefore, our paper seeks to investigate whether ‘green regions’, with an increased public and private commitment in environmental issues, are related to innovation of local firms. Using data on Spanish manufacturing firms and regions, we find that environmental technologies (especially in green energy), environmental investments, and environmental management at the level of regions are positively associated to local firms’ innovation.
