Against the backdrop of COP28, this chapter examines the fiscal allocations for the green economy in India across sectors for adaptation and its budget credibility. There is a significant deviation between what is announced and what is realised in green budgets across sectors. Using Detailed Demand for Grants data, the chapter analyses the sources of errors and partitions the errors into random or bias. Although the forecasting errors related to green economy allocations are predominantly due to random factors, there are sectors in which the errors are due to policy bias. Revisiting the assumptions and forecasting models are significant to minimise such errors. The link between fiscal transition and energy transition to tackle climate change crisis is not just confined to India. Fiscal Councils are the institutions which look into budget transparency and budget credibility issues reflected in fiscal marksmanship analysis in a few countries, though in India Fiscal Councils are yet to be constituted.
