This study analyzes the effectiveness of government incentives in accelerating green finance within India's complex and rapidly evolving economic landscape. Using a mixed-methods approach combining quantitative analysis of financial flows and qualitative assessment of policy frameworks, it is evaluated data from Indian states and central government initiatives over the period 2015-2024. The findings indicate that credit enhancement mechanisms and targeted subsidies yield the highest return on investment, particularly in renewable energy and climate adaptation sectors. A positive correlation was identified(r = 0.67, p < 0.001) between policy stability and private capital mobilization, with significant implications for India's ambitious climate action goals
