This study analyzes the role of innovation and entrepreneurship in the development of the green economy. The theoretical framework includes concepts such as the circular economy, eco-innovation, and sustainable entrepreneurship, while the methodology combines analysis of international policies (UN, OECD, EU), a comparative review of national strategies, and case studies. The results indicate that innovation not only reduces the environmental footprint of production but also enhances competitiveness and creates new jobs. The entrepreneurial sector serves as a key channel for commercializing sustainable technologies, yet it faces barriers such as limited access to finance and underdeveloped institutional support. The study concludes that the green economy is inseparable from systematic investment in innovation, entrepreneurial dynamics, and multidisciplinary cooperation among government, science, and industry.
