This research paper explores the shift from traditional capital systems to sustainable financing, focusing on green microfinance as a tool to support women-led micro-scale businesses in the energy sector. It emphasises the role of green financing in promoting financial inclusion and ecological conservation values. The study reviews literature on microfinance, gender mainstreaming, and sustainable finance, highlighting opportunities and challenges for women accessing green financing. Key recommendations include widespread awareness programs on green entrepreneurship, capacity building for women entrepreneurs in financial literacy and business proposal development, and government-led mentorship programs for micro-enterprises. The paper concludes that green financing can catalyze sustainable business models that integrate environmental stewardship and gender-sensitive approaches, fostering a more inclusive and resilient economic ecosystem.
