Abstract: The article addresses the pressing issue of integrating digital technologies into green entrepreneurship as a key factor for sustainable development and environmental security. Modern economic challenges require businesses not only to increase production efficiency but also to incorporate ecological aspects, which necessitates the combination of digital transformation with the greening of entrepreneurial activities. The study emphasizes that digital technologies-such as the Internet of Things (IoT), big data, artificial intelligence, blockchain, and cloud services-open new opportunities for resource optimization, emission reduction, and the creation of transparent supply chains. The paper analyzes scientific publications that highlight the impact of digitalization on the development of environmentally friendly business models, including works by both Ukrainian and international researchers. At the same time, it identifies that comprehensive research on the integration of digital solutions into green entrepreneurship, particularly in small and medium-sized businesses, remains insufficiently explored. This defines the novelty and practical relevance of the presented study. The research methodology is based on the analysis of scientific literature, statistical data, content analysis of EU strategic documents, and economic methods of evaluating the effectiveness of digital investments in eco-innovations. The findings outline the main directions of applying digital technologies in green entrepreneurship: reducing the ecological footprint, advancing energy efficiency and renewable energy sources, implementing circular economy principles, creating innovative business models, and strengthening corporate social responsibility. The author highlights key barriers that hinder the digitalization of environmentally oriented businesses: high initial costs, the need for skilled specialists, difficulties in integrating technologies into existing production processes, and cybersecurity risks. Based on this, practical recommendations are formulated to stimulate investments in digital solutions, develop unified emission management standards, enhance training programs, and expand international cooperation in the field of digital greening of businesses. The conclusions emphasize that digital technologies are becoming a decisive tool in shaping environmentally responsible entrepreneurship, ensuring not only increased economic efficiency but also fostering a new business culture oriented toward sustainable development.
