As climate change increasingly affects public infrastructure, agriculture, water systems and livelihoods, subnational governments are under growing pressure to integrate environmental sustainability into their fiscal frameworks. In India, where states are the key implementing units of public expenditure, climate-informed fiscal planning is essential to ensure both the efficiency of public investments and the achievement of long-term sustainability goals. This report addresses this imperative by developing a comprehensive Green Budget Framework for the state of Rajasthan and identifying concrete strategies for mobilizing green and climate finance to support its implementation. However, the typology is of Rajasthan but the approach to develop a green budget frame work can be adopted by other states too.
