Climate change has emerged as one of the most pressing global challenges, requiring immediate and innovative solutions. In this context, green technologies those designed to reduce environmental harm and promote sustainability play a crucial role. The protection and promotion of these technologies largely depend on the legal framework of Intellectual Property Rights (IPR). IPR not only safeguards the interests of inventors but also encourages innovation by granting exclusive rights, thereby stimulating research and development in eco-friendly technologies. This paper examines the vital relationship between IPR and environmental sustainability from a legal perspective. It explores how patents, copyrights, and technology licensing contribute to the development and diffusion of green technologies. The study further analyzes how international agreements such as the TRIPS Agreement and the Paris Agreement influence technology transfer between developed and developing nations. While IPR serves as a key incentive for innovation, it also creates barriers when excessive patent control limits access to affordable sustainable solutions. Through critical legal analysis, the paper highlights the need for a balanced approach, one that protects innovators while ensuring that environmentally beneficial technologies are mainly accessible for global use. The discussion also covers India’s efforts in aligning its patent laws and environmental policies with sustainable development goals. Finally, the paper suggests legal reforms and collaborative mechanisms that can promote equitable access to green innovations, ensuring that intellectual property serves as a tool for both innovation and environmental justice.
