This paper reviews the literature on environmental innovation (EI) and systematizes it by means of an original methodology identifying the main directions in which the literature on EI has developed over time. In order to do so, two algorithms are adopted and used to analyse a citation network of journal articles and books. The main path analysis reveals that this literature revolves around the following topics: i) determinants of EI; ii) economic effects of EI; iii) environmental effects of EI and iv) policy inducement of EI. Each of these topics is discussed and implications from the main findings as well as possible future research extensions are outlined
Eco-innovation plays a crucial role in reducing carbon emissions. Exploiting the consolidated IPAT/STIRPAT framework, this paper studies whether a relationship exists between green technological change (measured as stock of green patent) and both CO2 emissions and emission efficiency (CO2/VA). To investigate this relation, a rich panel covering 95 Italian provinces from 1990 to 2010 is exploited. The main regression results suggest that green technology has not yet played a significant role in promoting environmental protection, although it improved significantly environmental productivity. Notably, this result is not driven by regional differences, and the main evidence is consistent among different areas of the country

The main path analysis reveals that this literature revolves around the following topics: i) determinants of EI; ii) economic effects of EI; iii) environmental effects of EI; and iv) policy inducement in EI.

Innovation is a key element behind the achievement of desired environmental and economic performances. Regarding CO 2, mitigation strategies would require cuts in emissions of around 80-90% with respect to 1990. We investigate whether complementarity, namely integration, between the adoption of environmental innovation measures and other technological and organizational innovations is a factor that has supported reduction in CO 2 emissions per value added, that is environmental productivity. We merge new EU CIS and WIOD meso level data to assess the innovation effects on sector CO 2 performances at a wide EU level. We find that jointly adopting different innovations is not a significant factor to increase environmental productivity, neither for the entire economy nor for manufacturing or narrower ETS sectors. The only case where a complementarity arises is for Northern EU manufacturing sectors that integrate eco innovations with product and process innovations to support environmental productivity. We believe that the lack of integrated innovation adoption behind environmental productivity performance is a signal of the current weaknesses economies face in tackling climate change and green economy challenges. Incremental rather than more radical strategies have predominated so far; this is probably insufficient when we look at long-term economic and environmental goals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
