Trends in Green Innovation and Energy Efficiency: A Bibliometric Analysis

Green innovation and energy efficiency are fundamental pillars for society to achieve environmental sustainability, thereby generating an impact at organisational, economic and regulatory levels. A bibliometric analysis of scientific production in the Scopus database was carried out, using the PRISMA statement to identify 292 documents that met the inclusion criteria and using tools such as VOSviewer and Bibliometrix. The results show an exponential growth in scientific output equivalent to 24.8% of the annual growth rate, with the most cited keywords being green innovation, energy management, sustainability policies and circular economy. In addition, China stands out for research contributions to the topic of study and The United Kingdom and Switzerland exhibited a significant number of publications in the field, with notable contributions to scientific discourse. It was concluded that green innovation and energy efficiency are fundamental for sustainable development and that the main challenges are regarding the implementation of regulatory policies to reduce the effects of climate change. The evaluation of the effectiveness of regulatory regulation and its impact on sustainability promoted by countries was identified as a future line of research.
